Reset Button

Use the reset button with caution. The Reset button on the front panel of the switch resets the internal control microprocessor of the switch. Sometimes a reset clears a problem that appears to be the result of an unidentified error. Pushing the Reset button interrupts all traffic and forces re-initialization of the loop. The switch bypasses all ports and goes through normal power-on operations. Then the switch reconnects the network by initializing all the ports connected to active devices. Resetting the switch disrupts the network. This may affect performance, but does not corrupt data on disk drives attached to the switch. It does, however, erase any statistics and other management data that have been collected.

Connections

The following subsections describe the handling of GBICs and Fibre Channel cables.

Caution: GBICs are sensitive to static electricity. Static discharge from your clothing or other fixtures around you can cause damage. To prevent damage to the GBIC, wear a wrist strap or discharge leash to free yourself of static before touching it.

•Leave the device in its antistatic bag until ready to install it.

•Hold the GBIC by its edges and handle it carefully.

•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.

•Do not install any GBIC that appears physically damaged. This may result in permanent damage to the switch.
