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.
