Part 1: Mount the Switch
1. Attach the grounding strap to your bare wrist and to the ESD point on the chassis.
2. Ensure that the rack is properly secured to the building in its permanent location.
NOTE: To mount multiple units on the rack, mount the heaviest unit at the bottom of the
rack and mount the others from bottom to top in order of decreasing weight.
3. With 8 mounting screws—and cage nuts and washers if your rack requires
them—install front and rear mounting brackets on the left side of the rack in the
lowest position that has 14 U space for the chassis (15 U if you install the power cord
tray).
4. With 6 bracket screws, connect the front and rear brackets.
5. Repeat Steps 3 and 4 for the front and rear brackets on the right side of the rack.
6. (Optional) With 4 mounting screws—and cage nuts and washers if required—attach
the power cord tray to the rack.
7. Using a mechanical lift, position the switch in the rack onto the mounting brackets you
installed in the rack, and align the bracket holes with the rack holes.
8. Install a mounting screw—and a cage nut and washer if required—in each of the
24 front-mounting bracket holes.
Part 2: Connect the Switch to Earth Ground
1. Connect one end of the grounding cable to a proper earth ground, such as the rack in
which the switch is mounted.
2. Place the grounding lug attached to the grounding cable over the protective earthing
terminal on the left side of the chassis, and secure the lug to the terminal with the
screws and washers.
Part 3: Connect Power to the Switch
Power supplies come preinstalled in the chassis. For each power supply:
.
1. Ensure that the power supply is fully inserted and latched securely in the chassis.
2. Flip the Enable switch to the Standby position.
3. Squeeze the sides of the cord retainer clip. Insert the L-shaped clip ends into the
bracket holes on each side of the AC appliance inlet.
4. Insert the coupler end of the jumper cord into the AC appliance inlet.
5. Push the jumper cord into the slot in the adjustment nut. Turn the nut until it is against
the base of the coupler and the slot in the nut is turned 90° from the top of the switch.
6. If the AC power source outlet has a power switch, set it to the OFF (0) position.
7. Insert the jumper cord plug into the power source outlet.
8. If the AC power source outlet has a power switch, set it to the ON (|) position.
