Troubleshooting

This chapter provides information for troubleshooting problems on the Cisco ASR 903 Router.

BITS Port Pinout

The table below summarizes the BITS port pinout of the Front Panel “Building Integrated Timing Supply” RJ48 port.

8	—	—	Not used

GPS Port Pinout

The platform is capable of receiving or sourcing GPS signals of 1 PPS & 10 MHz. These interfaces are provided by two mini-coax 50-Ohm, 1.0/2.3 DIN series connector on the front panel. Similarly there are two mini-coax 50-Ohm connectors provided in the front panel to output this 1PPS and 10MHz.

The table below summarizes the GPS port pinouts.

Table 2. GPS Port Pinout
	10 Mhz (input and output)	1PPS (input and output)
Waveform	Input—Sine wave Output—Square wave	Input—Rectangular pulse Output—Rectangular pulse

Time of Day Port Pinout

The table below summarizes the TOD pinout for A900-RSP2A and A900-RSP3-3C-400 modules.

Note

This port requires the use of SHIELDED cable for GR-1089-core “Intra-Bldg lightning surge” protection. RS422 interface is per industry standard EIA-422 /RS422 specification.

Note

In order to comply with IEEE 1613.1-2013 the cables used to connect the 10MHz and 1PPS ports to other equipment must be less than 2 meters long in order to protect these ports from exposure to damaging transients.

Note

In order to comply with IEC 61850-3:2013 the 10MHz and 1PPS ports must be classified as Class 1 Reliability Level for Local Connection use in order to protect these ports from exposure to damaging transients.

Management Ethernet Port Pinout

A single management copper ENET port supporting 10/100/1000Base-T operation exists on each RSP. There is no direct access to the CPU of the other RSP. It uses a standard RJ45 jack.

Note

This is not a data plane port.

USB Console Port Pinout

Two individual Type-A USB connector are used for USB console and USB mass storage. One single USB 2.0 Type-A receptacle is provided on the RSP front panel for providing console access to ROMMON, IOS-XE and diagnostics. It operates as a USB peripheral only for connection to an external host PC. This requires the use of a Type-A to Type-A connector instead of a standard USB cable.

Note

The use of the USB console is mutually exclusive with the RS232 console/Aux port. While a USB cable is inserted, access is automatically switched to this port.

The other single USB 2.0 Type-A receptacle is provided on the RSP front panel for inserting external USB mass storage devices such as standard USB flash drives. It is used to load images, store configurations, write logs, etc. It supports operation up to 12Mbps.

The table below summarizes the USB console port pinout.

Fiber-Optic Specifications

The specification for optical fiber transmission defines two types of fiber: single-mode and multimode. Within the single-mode category, three transmission types are defined: short reach, intermediate reach, and long reach. Within the multimode category, only short reach is available. For information about optical SFP modules, see the documentation for the SFP module at:

http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html .

Cabling Guidelines

The guidelines are recommended during the installation of fiber cables:

Avoid the following actions that can stress the cable:
- Pulling or stretching beyond the specified pulling load rate
- Bending it beyond the specified bend radius
- Creating tension in the suspension runs
Do not touch the fiber tips of fiber cables.
Use single mode or multi-mode optical fiber cables as per the optical transceiver requirement.
Use fiber cleaner to clean the fiber tip as well as transceiver before inserting the fiber cable into the optical transceiver during installation.
To avoid excessive bending of fiber cable and efficient routing of cables, cable guides or cable brackets are recommended to be used with the chassis.

A900-RSP2 and A900-RSP3 LED Information

The PWR and STAT LEDs are available on the front panel. These LEDs provide power on the board (PWR) and overall router health (STAT) status. During power up state, these LEDs provide booting status and report errors.

Note

The digital code signing functionality validates the integrity and authenticity of the ROMMON image before booting it.

PWR LED State	STAT LED State	Indication	Comment
Light Green	Red	Power is OK and the field-programmable gate array (FPGA) is nfigured successfully, but FPGA image validation failed.	Image validation failed. System is in hung state.
Flashing Light Green and Green alternatively	Off	FPGA configured and core validated successfully. FPGA image passed the control to micro-loader to boot ROMMON.	System is up with ROMMON. Both the FPGA image is validated successfully, but the booted ROMMON (primary or secondary) is undetermined.
	Amber	The digital code signing functionality reported upgrade FPGA image validation error and is continuing with the FPGA image.	System is up with ROMMON. FPGA image is validated successfully, but the booted ROMMON (primary or secondary) is undetermined.
