CAUTION
Risk of service loss
Before seating or unseating an FP in a sparing
configuration, ensure that all the cables on the faceplate
are disconnected. Seating a cabled FP can cause a traffic
loss on the other FPs in the sparing configuration.
CAUTION
Risk of service loss
Whenever you install an FP that uses a control cable in a
sparing configuration, you must always seat the FP into
a slot on the shelf before you connect the control cable.
If you connect the control cable between the FP and the
termination or sparing panel before you insert the FP in
the shelf, you can disrupt service to the other FPs in the
sparing configuration.
• If the FP is an HSSI or V.11, you must first set the DIP switches
according to "Setting DIP switches on a V.11 function processor"
(page 520) or "Setting DIP switches on a HSSI function processor"
(page 518).
• For initial installations, ensure that each FP type will be inserted into the
slot that has been or will be configured for that FP. The hardware
configuration must match the software configuration for the slot.
• The bottom of a Nortel Networks Multiservice Switch 7400 FP is
typically where the status LED is located.
• Follow "Avoiding damage from static electricity" (page 208) to protect
the card from damage by ESD or from transferring ESD to other
hardware.
1 Hold the FP in front of the shelf assembly so that:
• you do not touch the copper-colored metal EMI gasket at the edge of
the card
• its faceplate faces you
