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.
