Managing Cables; Verifying Correct Operation And Backing Up The Configuration - IBM SAN768B-2 Installation, Service And User Manual

Managing cables

Attention: The minimum bend radius should be no smaller than 10x the cable
radius. The minimum bend radius for a 50 micron cable is 5 cm (2 in.) under full
tensile load and 3 cm (1.2 in.) with no tensile load.
Note: Contact your IBM representative for options regarding different cable and
Cable management recommendations:
v Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to
v If ISL Trunking is in use, group the cables by trunking group. The ports are
v Use only hook-and-loop fasteners for securing optical cables. Do not use cable
v For easier maintenance, label the fiber optic cables and record the devices to
v Use the cable management fingers attached to the rack rails to organize the
v Keep LEDs visible by routing port cables and other cables away from the LEDs.
For the procedure to install the ICL cables see "Removing and replacing
inter-chassis link (QSFP) cables" on page 95.

Verifying correct operation and backing up the configuration

To verify correct operation and to back up the system, follow these steps.
1. Check the LEDs to verify that all components are functional. For information
2. If necessary, log on to the switch by Telnet, using the admin account.
3. Verify the correct operation of the system by entering the switchShow
4. Verify the correct operation of the SAN768B-2 in the fabric by entering the
