Removing/Replacing TRIM Cards
Introduction This section describes the removal and replacement of TRIM cards.
Caution
6500 cards and their components are sensitive to static discharge, which can damage
components. Use proper handling and grounding precautions, including the use of an
anti-static grounding strap, whenever you handle a card.
Before Removing
TRIM Cards Before removing the TRIM card from the Modulus enclosure, disconnect the LAN
cable and detach the TRIM rear filler panel from the TRIM card backplane.
Failure to do so could damage the LAN cable or the TRIM card. The following
caution label on the processor card is a reminder:
“REMOVE LAN I/O CABLE, REAR FASTENERS AND FRONT FILLERS
BEFORE REMOVING THIS CARD.”
Removing the
TRIM/Processor
Card Follow these steps to remove the TRIM/processor card from the nest:
Updating LAN Port
MAC Address The BIA (Burned In Address) is a unique LAN MAC address that is supplied by a
PROM chip on the TRIM card. The BIA is used as the LAN port MAC address if the
Port MAC Address parameter (in the Port configuration record) is set to a default
value of 00-00-00-00-00-00.
If you replace the TRIM card, reboot the node to reset the LAN port address to the
new BIA value contained on the replacement TRIM card. If, however, you want to
use the BIA address from the removed card, update the node configuration to ensure
that the older BIA address is used.
Step Action
1 Detach the LAN cable from the backplane.
2 Using a flat-head screwdriver, unscrew the captive hardware that
attaches the TRIM card rear filler panel to the TRIM card backplane.
3 Detach the two Modulus front filler panels that cover the TRIM card.
4 Pull out the TRIM/processor card. When detaching a TRIM card from
its processor card, follow the procedures in “Installing and Connecting
a TRIM Card” section on page 2-45 in reverse order.
