Identifying a Line Card

ATM, packet-over-SONET, and 16-port 10/100 BASE-TX line cards are T-series line cards introduced with the 3.1 firmware release. The following Gigabit Ethernet line cards are also T-series line cards: SSR-GSX31-02, SSR-GLX39-02, and SSR-GTX32-02. Network administrators can also identify a T-series line card using the system console. The command “system show hardware” displays “(T-Series)” if the line card is a T-series line card.

Example 1:

ssr# system show hardware

:

:

Slot 13, Module: 16-10/100-TX (T-Series) Rev. 1.0

The example above shows the display for a T-series line card.

All “-AA” line cards can be identified by the “-AA” suffix in the part number on the module label. This is the easiest way to verify whether a line card is a “-AA” or “non-AA” line card. Network administrators can also identify a “-AA” line card using the system console. A chip ID register called the “Service String” is used to identify the component used on each line card. The command “system show hardware verbose” displays the “Service String” for each line card, which can be used to identify the version of the ASICs used. This command is available in firmware 2.2.0.1 and above.

In the “Service String” output, look at the revision numbers that immediately follow the letters “D” (or “G” for Gigabit Ethernet line cards), “I,” and “O.” Compare the revision numbers with the following to determine if the line card is a “non-AA” or “-AA” revision.
