Appendix G:
Replacing a Module
General
This appendix shows how to replace modules in the LDX00 chassis.
Tools
•
6-inch flat-tip screwdriver
•
6-inch posidrive screwdriver
•
Possibly a replacement Power Supply
Procedure
Network Module
The procedure for replacing a network module (Transponder, Mux, Demux, Management,
Service, 1+1, OADM, OA, ESCON, or GM2) of the LDx00 is as follows:
1. With a 6-inch posidrive screwdriver, undo the two Mounting Screws (
2. Push down the Handle/Ejector/Extractor, and slide out the module.
3. Holding
the
new
module by the panel, place it between the left and right rails in the slot.
Then slide it until its panel is
almost
level with the front panel of the LDx00. (This assures
that the module’s connector is inserted into place.) Pull up the handle/ejector/extractor to
lock the module in position.
4. Fasten the module with the two Mounting Screws using a 6-inch posidrive screwdriver.
Power Supply Module
The LD400 has no Power Supply module.
The procedure for replacing the Power Supply module of the LD800 is as follows:
1. Ensure
that
all
power to the LD800 is cut off. Specifically, disconnect all LD800 power
cords from the power line (mains).
2. With reference to
using a 6-inch posidrive screwdriver, loosen the
four mounting screws at the top and bottom of the module panel.
3. Holding the module by the handle with one hand and pressing against the LD800 chassis
with the other, pull out the module.
4. Check/replace the module.
5. Tighten the four mounting screws at the top and bottom of the module panel.
SFP Module
The procedure for replacing an SFP in a network module is as follows:
1. If the SFP module has a latching mechanism, while holding the SFP module with one
hand gently release the latch with the other hand. Usually, the latch handle is a wire
frame around the SFP module. To release the latch, swing down the wire frame.
2. Pull out the SFP module.
3. Swing up the latch handle around the SFP module and put it away.
4. Holding
the
new
SFP module with the right side up, slide it about half-way into the SFP
receptacle.
