Planning Loop Configuration
Follow these guidelines when you plan your fibre channel loop:
1. Determine the devices (storage and servers) in the loop and their physical location.
2. Make sure that the necessary cables and MIAs are on hand. Make sure that the
cabling is the correct length and type (copper or fiber optic) for the storage and
servers. Note the following:
•
If you plan to cascade two hubs, make sure you have the cascade cable.
•
It is a good idea to label the ends of the cables that are to be connected to the
hub with the device names, or an appropriate indication of them.
•
For the connection between the hub and the console terminal or PC, use only
the serial cable and adapters included with the hub.
3. Determine the order in which you want to cable devices to the hub. You can skip
ports when you attach cables to the hub.
Fibre Channel Hub ports are numbered as shown on the front panel, with ports 5
and 10 on the rear; see Figure 2-1.
LEDs on the front panel show activity for the eight ports on the front panel and the
two ports on the rear panel; see Figure 2-7.
