4.2 Power connections
If the unit is rack-mounted in a slide assembly, leave enough cable to form a service
loop approximately 40 to 46 cm (16 to 18 in.). See section 4.3 for details on creating
service loops.
Procedure 4-2 To connect to power
1 Ensure that the power switch is in the Off position.
2 Connect the power cord to the ac receptacle at the back of the unit (see Figure 4-3).
If the unit is mounted in a slide drawer, secure the power cord as described in
section 4.3.
3 Plug the other end of the power cord into an unswitched ac outlet.
4 Turn on the unit power switch.
The LEDs on the faceplate and rear panel run through their startup diagnostic
patterns. See section 4.4 for more information on startup diagnostics.
