Chapter 3: Fibre Channel Hub Setup and Cabling
Using Copper Cabling
Follow these steps to cable the servers and storage to the hub with copper cabling:
1.
Power off the servers and workstations (FC-AL nodes) that are to be connected to
the hub, following procedures in the manuals for those systems.
Note:
During normal hub operation, you can attach devices to the Fibre Channel
Hub without powering them off; however, powering off these devices is
recommended when you are setting up the hub connections for the first time.
2. Cable the servers, workstations, and storage to the hub ports. You need not cable to
adjacent hub ports; that is, you can skip ports when attaching cables.
3. Tighten the jackscrews on each DB-9 connector to ensure EMC emissions
compliance and proper system operation.
Using Fiber Optic Cabling
To connect devices to the hub with optical cabling, you must use MIAs. Follow these
steps to cable the servers and storage to the hub with fiber optic cabling:
1.
Power off the servers and workstations (FC-AL nodes) that are to be connected to
the hub, following procedures in the manuals for those systems.
Note:
This step is required for fiber optic cabling. Attaching the connectors before
applying power to the system confines all light within the fiber optic wave guide,
which practically eliminates any potential hazard.
2. Taking care not to touch the tips of the fiber optic cable connections, remove the
protective caps from each cable’s connectors and place an MIA on each connector.
This connection is keyed.
3. Attach an MIA to each end of each cable.
