5. Tighten the screws to secure the mounting bracket to the chassis and
lock the power cord in place.
6. If you are using redundant power supply modules, repeat Step 1 on
page 461 through Step 5 to install a cord lock on the second AC power
cord.
7. Plug the supply end of each power cord into a separate AC branch circuit.
Note: If the AC supply outlet does not have a locking connector, make
sure you connect a permanent grounding wire to the power
supply bay (see Install the Grounding Wire).
Install the Grounding Wire
If the supply end of the power cord cannot be locked to prevent an
accidental disconnect, install a permanent grounding wire to connect the
library chassis to earth ground. A 10 foot (3 meter), 14 gauge coated
grounding wire, 10-32 screw, and star washer are supplied with the library.
1. Using the star washer and the 10-32 grounding screw, connect the
grounding wire to the PEM nut below one of the AC power cord
connectors.
2. Connect the free end of the wire to earth ground.
Figure 289 Secure the cord lock assembly to the chassis.
Figure 290 Connect the grounding wire.
