Main
Backplane
Covers
Electrical connector modules (ECM) are used for network interface cabling using
standard copper/coax cables and connectors. Three types of main backplane covers are
used (alarm and timing cover, power cover, and blank covers) to protect the main
backplane where ECMs are not plugged in.
Covers are removed from the Traverse shelf during installation and cabling activities.
Covers must be replaced after cabling is complete to ensure air cooling from shelf to
shelf and electromagnetic interference (EMI) protection during normal operation.
Each cover is removed from the shelf chassis using a flat blade screwdriver to remove
the screws.
Important:
Always wear a properly grounded Electrostatic Discharge
(ESD) wrist strap when removing back covers from the Traverse shelf as
there are static-sensitive components on the main backplane.
