Grounding

553-3121-210

Standard 3.0

Do not staple fiber optic cable or bend it beyond a minimum 35 mm

bend radius (90° soft bend).

Incorrectly connected fiber optic cables may cause the following

– a series of repetitive fault indicating messages

– a complete failure of the expansion cabinet

If fault indicating messages appear, check the fiber optic cable

connections.

Since messages are stored in a buffer, they may continue to be

displayed until the buffer is empty. After checking the cable

connections, wait a couple of minutes for the messages to stop.

Grounding for the expansion cabinet is provided by a #6 AWG ground wire

installed between the main and expansion cabinets.

Note: It is preferable that all cabinets on a site be powered from the same

power panel.

For more information on grounding, refer to

Each cabinet requires a dedicated outlet. All outlets should, if possible, be

connected to the same power panel. Refer to

for more information about power requirements.
