troubleshoot problems with your fibre loop switch:
•

General Maintenance Considerations

•

Connections

•

Temperature Control

General Maintenance Considerations

To protect the switch for longer use, we recommend that you:
•

Periodically vacuum the external surfaces of the switch to remove dust.

•

Do not drop fiber optic cable connectors onto hard surfaces. This can cause

internal glass fractures and intermittent signals.

•

Keep unused cable ends covered to prevent contamination from obscuring or

attenuating the light signals

•

Keep unused GBIC connections covered to prevent contamination from

obscuring or attenuating the light signals.

•

Always follow the GBIC manufacturer’s recommended procedures for

cleaning the GBIC. This is especially true of the type of solvent used for

cleaning optical surfaces.
