AS920 Serial console pinout

some genius at Cisco decided that i would be a good idea to implement the serial console port (usually a RJ45 or DB9 connector) as USB-A connector. :-(

I have some of these boxes implemented in fiber POPs and like to implement Console-servers for Out-of-band management purposes in these fiber distribution sites. As long as i don't find any specific "Cisco-ASR920 to worldwide common RJ45" cables i think that i have to build these by my own.

i tried the pinout as described in this Cisco community article (https://community.cisco.com/t5/networking-documents/asr-920-series-routers-console-port/ta-p/3754675), but this doesn't work for me.

has anybody successfully crafted such a cable and can provide me the layout how he connected the pins?

 Hello Everyone,

 

I am a 20+-year veteran user of Cisco routers and switches but I am fairly new to the ASR 920 series. Recently, I purchased 4 asr920’s for a specialized project. Imagine my surprise when I went to set them up and found that the console port was USB only! Well, no big deal. Since I have hundreds of console cables lying around, I did not order one in this purchase. So, I followed the instructions in the installation manual. I found a type-a   -to-  type-a cable and connected my laptop. I downloaded Cisco’s ‘driver’ and installed it.No good. It did not work. I uninstalled and re-installed a few times but still nothing. I grabbed another computer and tried it. I also got another cable. Still nothing.

 

I google-researched the issue and learned that, low and behold, the ‘USB’ port is not USB at all, but is plain old rs232. Some dummy (fire this guy!) decided to get creative and use a USB chassis connector for the rs232 serial port. Since I had an immediate need, I researched the pin-outs of the connectors and systems involved. I took a usb cable and cut one end off. The I got a light-blue Cisco console cable and cut the RJ45 end off. I then spliced the two cut ends together. After fiddling with it for a few minutes I had it working. I was able to get ip addresses on each of my four routers and get them connected to my lab network for further configuration.

 

Now I won’t go into why they would use a usb connector for an rs232 port, or why the installation guide says to connect it to your pc usb port or why they have you install a driver when it is not needed….  Those are thoughts for another day. My purpose here is to share with everyone a simple way to make yourself a console cable for the asr920 that will work and is a bit more elegant than my ‘McGiver’ cable.

 

The easiest thing to do is take a usb cable, cut one end off, and crimp on a RJ45 mod plug. With this cable, one can then use a cheapo RJ45 inline coupler to couple this new cable to the end of a ‘standard’ Cisco console cable. If you don’t have a crimp tool, then you could simply use a biscuit jack on the end of the usb cable instead of the modular plug.

 

Now bear in mind that most usb cables have a wire color standard but I’m sure there are some out there that use different colors. The color doesn’t really matter; it is what wire connects to what pin that is important. It is advisable to use an ohmmeter to verify the pin-out if necessary.

 

The correct cable pin-out is shown below. Just connect a mod plug on the end of a usb cable, couple this with a regular console cable and you’ll be in business!!

 

usb                                             8-pos mod plug

cable pin#                                   (rj45 pin #)

---                                                ---------------------

1              red (+5v)                           2

2              white (data-)                     3

3              green (data+)                    6

4              black (ground)                   4

Just finished installing a ASR920 tonight... I had the same issue, just order 6 of those console kits.... This is really annoying...

My rack mount brackets don't look like that...

Some changes from Cisco Norm for the ASR920
- No RJ45 console port, very disappointing
- The power plug for AC is a C15 not a normal C13
- Services Instances are 1-4000 not 4096. We usually keep the service instance id and the stag the same. You couldn't add another 96 service instances.
- Interface layout on the switch would have been nice if it was like cisco switch top left is the first port, but on the asr920 it's the bottom right is port G0/0/0.
- interface number start with 0 like a router, instead of 1 like the ME3800's
- Management Interface vrf name is forced to Mgmt-intf, you can't change it.
- It's weird that the power supplies stick out a 1/4" inch

Power on the Device

After the device is mounted, perform these tasks to complete the installation:

  • Power on the device.
  • Connect the front-panel ports.

Connect SFP Modules

Before you begin this task, ensure that you have read and understood the safety warnings in the Safety Precautions for Module Installation and Removal section of the Safety Warnings chapter.

Use only Cisco SFP modules on a Cisco device. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP modules meet the requirements of the device.


Caution

We recommend that you wait for 30 seconds between the removal and insertion of an SFP module from the device. The wait period allows the transceiver software to initialize and synchronize with the device. Changing an SFP before this wait period could result in transceiver initialization issues that disable the SFP.


This section provides procedures for installing and connecting SFP modules. Also, it provides the procedure for removing SFP modules.

Install SFP Modules

The figure below shows an SFP module that has a bale-clasp latch.


Caution

We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.




To insert an SFP module into the module slot, follow these steps:

SUMMARY STEPS

  1. Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
  2. If the SFP module that you are using has the markings, use them to identify the top side of the module.
  3. Align the SFP module in front of the slot opening.
  4. Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear of the slot.
  5. Insert the cable connector into the SFP module:

DETAILED STEPS


Step 1

Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Some SFP modules identify the top side of the module with send (TX) and receive (RX) markings or arrows that show the direction of the connection.

Step 2

If the SFP module that you are using has the markings, use them to identify the top side of the module.

Step 3

Align the SFP module in front of the slot opening.

Step 4

Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear of the slot.



Caution 

Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light. Store the dust plugs for later use.

Step 5

Insert the cable connector into the SFP module:

  • For fiber-optic SFP modules, insert the LC cable into the SFP module.
  • For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.

Remove SFP Modules

To remove an SFP module from a module receptacle, follow these steps:

SUMMARY STEPS

  1. Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
  2. Disconnect the cable from the SFP module, and insert a dust plug into the cable end.
  3. Unlock and remove the SFP module, as shown in the following figure.
  4. Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.
  5. For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.
  6. Place the removed SFP module in an antistatic bag or other protective environment.

DETAILED STEPS


Step 1

Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2

Disconnect the cable from the SFP module, and insert a dust plug into the cable end.

Tip 

For reattachment, note which cable connector plug is send (TX) and which is receive (RX).

Step 3

Unlock and remove the SFP module, as shown in the following figure.

If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch.



Step 4

Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.

Step 5

For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.

Step 6

Place the removed SFP module in an antistatic bag or other protective environment.


Connect Gigabit Ethernet Ports

You can choose to connect either a copper or a fiber cable in the Gigabit Ethernet ports.


Note

The device 10/100/1000 ports configure themselves to operate at the speed of devices to which they are attached. Autonegotiation is enabled by default in the chassis. You can manually set the speed and the duplex parameters. If the device to which the ports are attached, does not autonegotiate, low performance or no linkage may result.

To maximize performance, choose one of these methods for configuring Ethernet ports:

  • Have ports autonegotiate both speed and duplex.
  • Set the port speed and duplex parameters on both ends of the connection.

Note

You can use the mdix auto command in interface configuration mode in CLI to enable automatic media-dependent interface with crossover detection. After you enable, the device detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connecting to a copper 10/100/1000 port. If the mdix auto command is not enabled, connect the cable through SFP module.

SUMMARY STEPS

  1. Connect to workstations, servers, and devices, connect a straight-through cable to an RJ-45 connector on the front panel. When connecting to devices or repeaters, use a crossover cable.
  2. Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both the device and the connected device have established a link.
  3. Reconfigure and reboot the connected device if necessary.
  4. Repeat Steps 1 to 3 for each device that is to be connected.

DETAILED STEPS


Step 1

Connect to workstations, servers, and devices, connect a straight-through cable to an RJ-45 connector on the front panel. When connecting to devices or repeaters, use a crossover cable.

Step 2

Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both the device and the connected device have established a link.

If the port LED does not turn on, check whether the device at the other end is turned on or whether there is any failure.

Note  On user network interface (UNI) ports, the port LED turns green after the link is established.
Step 3

Reconfigure and reboot the connected device if necessary.

Step 4

Repeat Steps 1 to 3 for each device that is to be connected.


Connect to SFP Modules

This section describes how to connect to SFP modules.

Connect Fiber Optic SFP Modules


Caution

Do not remove the rubber plugs from the SFP module port or from the fiber optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.


Procedure

Step 1

Remove the rubber plugs from the module port and fiber optic cable, and store them for future use.

Step 2

Insert one end of the fiber optic cable into the SFP module port.

Step 3

Insert the other end into a fiber optic connector at a target device.

Step 4

Observe the port's LED status.

The LED turns green when the device and the target device establish a link.

If the LED is off, check whether the target device is turned on, or whether there is any failure in the target device.

Step 5

If necessary, reconfigure and restart the device or target device.


Install the Chassis Ground Connection

Before you connect the power or turn on the power to the router, you must provide an adequate chassis ground (earth) connection to your router.

This section describes how to ground the router chassis. The grounding lug location is on the back panel of the router.

Warning

This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045


Guidelines for DC-Powered Systems

Basic guidelines for DC-powered systems include the following:

  • Each chassis power supply has its own dedicated input power source. The source must comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, and IEC 60950 standards.
  • Protect the circuit by a dedicated two-pole circuit breaker. Ensure that the circuit breaker is sized according to the power supply input rating and local or national code requirements.
  • The circuit breaker is considered as the disconnect device and is easily accessible.
  • The system ground is the power supply and chassis ground.
  • Use the grounding lug to attach a wrist strap for ESD protection during servicing.
  • Do not connect the DC return wire to the system frame or to the system-grounding equipment.
  • Ensure that the DC return is grounded at the source side.

Guidelines for AC-Powered Systems

Basic guidelines for AC-powered systems include the following:

  • Each chassis power supply has its own dedicated branch circuit.
  • Ensure that the circuit breaker is sized according to the power supply input rating and local or national code requirements.
  • The AC power receptacles that are used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles must connect to protective earth ground at the service equipment.

Prevent Power Loss

Use the following guidelines to prevent power loss to the device:

  • To prevent input power loss, ensure that the maximum load on each circuit supplying the power is within the current ratings of the wiring and breakers.
  • In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the device, which can have substantial current-draw fluctuations due to bursty data traffic patterns.

Determining power requirements is useful for planning the power distribution system to support the device.

Connect the USB Type A cable to the PC.

Step 3

To communicate with the router, start a terminal emulator application, such as Microsoft Windows HyperTerminal. This software should be configured with the following parameters:

  • 9600 baud

  • 8 data bits

  • no parity

  • 1 stop-bit

  • no flow control
