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.
