Tip
Step 5
After you enter the required information for all cards in hardware survey worksheet, use
verify that each card is installed in a slot that supports that card type. You also need to verify that the
correct back cards are installed for the corresponding front cards.
Note
If any of the cards are installed incorrectly, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX
8950, Cisco MGX 8830, and Cisco MGX 8880 Hardware Installation Guide, Releases 2 Through 5 for
instructions on installing the cards correctly.

You can not run the dspcd command on the SRM itself, because all SRM card configuration is
done from the PXM card. Enter dspcd <SRM_slot_number> at the PXM to display information
about the SRM cards in your switch.
In the worksheet for your switch type, write down the following information for each card:
Upper back card type that appears in the Upper Card column of the Inserted Card row.
–
Lower back card type that appears in the Lower Card column of the Inserted Card row.
–
Another way to display a detailed report on a card is to enter the cc command to select the card,
then use the dspcd command without a slot number. However, the preferred method is to use the
dspcd command with a slot number because this method can display information on a card when
card errors prevent access through the cc command.
The locations where the upper and lower back cards are installed are also called bays. On a
Cisco MGX 8850 (PXM1E/PXM45) or Cisco MGX 8950 switch, each slot has an upper and a
lower bay for back cards.
