Installing the EWDM Passive Optical System
Step 2
Gently push the OADM module or booster amplifier into the two-slot chassis. Ensure that you line up
the captive screws on the OADM module or booster amplifier with the screw holes on the two-slot
chassis.
Note
You may have CWDM and EWDM optical modules in the same chassis.
Step 3
Tighten the two captive screws with the Number 2 Phillips screwdriver. Do not overtighten.
Step 4
Do not remove the optical bore dust plugs at this time.
Step 5
If you are installing a MUX or OADM and will not be using it with a booster amplifier, connect the AMP
IN to the AMP OUT port of the EWDM module.
