Removal and Replacement Procedures<br />

Removing and Installing the DC-Input Power Supplies<br />

Step 4<br />

Step 5<br />

Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power<br />

supply (Figure 4-47).<br />

Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according<br />

to local and national installation requirements. Use only copper wire.<br />

Note<br />

6000 W power supplies ship with AWG #4 lugs with 45-degree angled, 2-hole compression lug<br />

for both power and ground wiring. Additional lugs for different wire size should be purchased<br />

separately.<br />

Note<br />

The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts<br />

are centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you<br />

use an appropriately sized industry standard 45 degree angled, 2-hole, standard barrel<br />

compression lug for both power and ground lugs (for example, on AWG #4 wires, Panduit part<br />

number LCC4-14AWH-L or equivalent). The power supply ground studs, located beside the<br />

terminal block.<br />

Note<br />

For 6000 W power supplies, use fine-stranded copper conductors rated for 90-degrees Celsius<br />

for North American installations.<br />

Note<br />

The 6000 W DC-input power supply provides voltages of 2800 W, 4500 W, or 6000 W. Select<br />

2800 W by wiring any two positive (+)/negative (-) terminal pairs in any sequence. Select<br />

4500 W by wiring any three positive (+)/negative (-) terminal pairs in any sequence. Select<br />

6000 W by wiring all four terminals. The Cisco IOS software detects the wired inputs and sets<br />

the proper system power.<br />

Note<br />

If you are wiring for 2800 W for a single power supply, proceed to Step 7; if you are wiring<br />

2800 W for a redundant power supply, proceed to Step 7 and then Step 10. In either case, proceed<br />

to step 14 upon completion.<br />

Note<br />

If you are wiring for 4500 W for a single power supply, proceed to Step 8; if you are wiring<br />

4500 W for a redundant power supply, proceed to Step 8 and then Step 11. In either case, proceed<br />

to step 14 upon completion.<br />

Note<br />

If you are wiring for 6000 W for a single power supply, proceed to Step 9; if you are wiring<br />

6000 W for a redundant power supply, proceed to Step 9 and then Step 12. In either case, proceed<br />

to step 14 upon completion.<br />
