_____________________ Caution _____________________
Static electricity can damage modules and electronic components.
We recommend using a grounded antistatic wrist strap and a
grounded work surface when handling modules.
For an installation, at a minimum, you have to:
1. Place the hub on an acceptable surface or install it in the rackmount.
2. Install one or more GBIC modules. Gently push the GBIC module into
an available port on the hub until you feel the GBIC module click into
place. The GBIC module has a built-in guide key that prevents you from
inserting it incorrectly. Do not use excessive force.
3. Connect the optical fiber cables. To do this, plug one end of an MMF
cable into one of the GBIC modules installed in the hub. Attach an
MMF cable for all active port connections. Unused ports or improperly
seated GBIC modules remain in loop bypass and do not affect the
operation of the loop.
4. Attach the other end of the MMF cable to either the KGPSA-CA adapter
or to the HSG80.
5. Connect power to the hub using a properly grounded outlet. Look at the
power indicator on the front of the hub to make sure that it powered on.
For more installation information, see the Fibre Channel Storage Hub 7
Installation Guide.
6.8.2.2 Determining the Hub Status
Because the DS-SWXHB-07 hub is not a manageable unit, examine the
status of the LED indicators to make sure that the hub is operating correctly.
The LED indicators will be particularly useful after you have connected the
hub to the KGPSA-CA host adapters and the HSG80 controller. However,
at this time you can use the LEDs to verify that the GBIC connectors are
installed correctly.
At power on, with no optical cables attached, the green and amber LEDs
should both be on, indicating that the port is active but that the connection
is invalid. The other possible LED states are as follows:
• Both off: Not active. Make sure that the GBIC is installed correctly.
• Solid green: Indicates presence and proper functionality of a GBIC.
• Green off: Indicates a fault condition (GBIC transmitter fault,
improperly seated GBIC, no GBIC installed, or other failed device). The
port is in bypass mode. This is the normal status for ports without
GBICs installed.
