system I/O card on the Cisco 6100 backplane.
b.
Disconnect the end of the cable that attaches to the transmit (J3) DS3 BNC connector on the
system I/O card on the Cisco 6100 backplane.

Disconnect the Subtended Network Configuration
If have a subtended network configuration and you need to prepare the rack to accommodate the fan
tray and install the thermal guard, you will need to complete the following steps to disconnect the
system I/O card on the subtending host chassis backplane and the DS3 subtending I/O card on the back
of each subtended node chassis backplane:
Step 1
Remove the coaxial cables from the two DS3 BNC connectors (J3 [TX] and J4 [RX]) for the
