Chapter 4 Preparing FRSM12 Cards and Lines for Communication
Managing Firmware Version Levels for FRSM12 Cards
Initializing FRSM12 Cards
Before a FRSM12 card can operate, it must be initialized in a switch slot. The initialization process
defines the FRSM12 runtime software version that will run on the card and identifies the slot in which
the card operates. To initialize an FRSM12 card, use the following procedure.
Note The PXM45 card supports a maximum of 99 lines on the switch. As you add FRSM12 cards, verify
that the line count for all AXSM and FRSM12 cards does not exceed this number.
Step 1 If you have not already done so, determine the software version number for the card by referring to the
Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E).
Tip If you have trouble locating the runtime firmware version level, use the filenames on the PXM45
hard disk to determine the level. For more information, see “Determining the Software Version
Number from Filenames,” in Chapter 7, “Switch Operating Procedures.”
Step 2 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 3 To set the firmware revision level for a card, enter the setrev command:
mgx8850a.7.PXM.a > setrev <slot> <version>
Note Each card should be initialized only once with the setrev command. The only other time you
should enter the setrev command is to initialize cards after the configuration has been cleared
with the clrallcnf, clrcnf, or clrsmcnf commands.
Replace <slot> with the card slot number and replace <version> with the software version number. For
example,
mgx8850a.7.PXM.a > setrev 4 3.0(0)
After you enter the setrev command, the system status LED blinks red until the firmware load is
complete, and then it changes to non-blinking green.
Step 4 To verify the activation of a card for which the status was previously listed as Failed/Empty, enter the
dspcds command. The status should change to Active/Active.
Verifying Card Firmware Version Levels
When you are having problems with your switch, or when you have taken delivery of a new switch but
delayed installation, it is wise to verify the firmware versions installed on the switch. If newer versions
of this firmware are available, installing the updated firmware can prevent switch problems.
