Removing an FP
Remove an FP from a shelf to empty the slot.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You must identify from the description of the FP in 241-1501-200
Passport 15000, 20000 Hardware Description whether the faceplate has
small form pluggable (SFP) optical modules. When such an FP is
removed due to a failure, its SFPs are to be removed and kept for re-use.
When an FP that uses SFP modules is to be re-deployed, each optical
module socket (port) on the FP must be re-configured to match the
version of SFP that will be plugged into it.
• The FP to be removed must be locked in software.
• As each cable is disconnected between an electrical FP and its sparing
panel, software alarm 7054 0100 is generated.
Procedure steps
1 At the front of the Passport 15000 or 20000 switch, locate the FP to be
replaced. See the figure “Locations of FPs” (page 753).
2 Record the position of each cable connector relative to the label of the
connector on the faceplate. Each cable should already have been labeled
with port connection information that will enable you to quickly reconnect
the cables to appropriate ports.
3 For fiber optic cards with cable hoods on the faceplate of the card, release
the hood by turning the lower latching screw counter-clockwise a 1/4 turn
with a slotted screw driver. Turn the screw by hand, not a power tool. Lift
the hood upwards and hold it perpendicular to the faceplate.
CAUTION
Risk of service interruption
Unseating an FP while at least one traffic port cable is still
connected to the faceplate means that any PNNI links and
some services (for example, ATM) to that FP through that
port will be dropped and will not recover when a
replacement FP is returned to service. Always disconnect
all cables after locking a card and before unseating it.
