Ethernet Ferrite Choke Installation
If NEBS compliance is required, install the ferrite chokes included in the NEBS
Compliance Upgrade, Feature Number 4200-F4-000. The smaller of the two ferrite
chokes must be installed on the alarm cable, if used. (See Alarm Interface on
page 2-10.) The larger of the two ferrite chokes must be installed on any Ethernet
cables used:
Procedure
1. Open the ferrite choke. Lay any cable connected to the 10/100BaseT ports or
1000BaseT port in the ferrite choke.
2. Snap the ferrite choke shut around the cables and slide it as close as possible
to the chassis.
3. Secure the ferrite choke in place with a cable tie.
