Replacing an OSC SFP Module
NOTICE
Service-disruption hazard
A card reseat is service impacting if the card is currently carrying services. To discover if
any services are currently carried over a card, perform the procedure “Checking for
Services
on a Port” (p. 3-10). If there are services currently carried over the card, it may
be
best to wait for a maintenance window before reseating the card.
Note: You must complete this entire replacement procedure within 5 minutes, or a
insert a blank after pulling the LD (ALPHG, AHPHG, AHPLG, ALPFGT, or OSCT
pack) from the slot in Step 3.
...................................................................................................................................................................................................
1
Ensure that all of the fibers connected to the LD are labeled.
...................................................................................................................................................................................................
2
Remove and cap all of the fibers connected to the LD pack.
...................................................................................................................................................................................................
3
Remove the LD from the shelf, the OSC SFP is mounted inside the pack.
...................................................................................................................................................................................................
4
Ensure that all of the OSC fibers connected to the OSC SFP module are labeled.
...................................................................................................................................................................................................
5
Remove and cap all of the fibers connected to the OSC SFP module.
...................................................................................................................................................................................................
6
Release the latch on the OSC SFP module. The latch used to secure the module in the
OSC SFP port may use either a lever or push-button locking mechanism:
• To release a lever latch, lift the latch 90 degrees so that it is perpendicular to the card
faceplate.
• To release a push button latch, depress the push button located on the side of the OSC
SFP module.
...................................................................................................................................................................................................
7
With the latch in the release position, grasp the OSC SFP module on both sides and
remove it from the OSC SFP slot.
...................................................................................................................................................................................................
8
Ensure that the specifications for the replacement OSC SFP module (protocol,
wavelength, and reach) match the specifications of the removed OSC SFP module.
