Chapter 4 Removal and Replacement Procedures
Step 4 Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power
supply
Step 5 Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according
to local and national installation requirements. Use only copper wire.

(Figure 4-47).
6000 W power supplies ship with AWG #4 lugs with 45-degree angled, 2-hole compression lug
for both power and ground wiring. Additional lugs for different wire size should be purchased
separately.
The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts
are centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you
use an appropriately sized industry standard 45 degree angled, 2-hole, standard barrel
compression lug for both power and ground lugs (for example, on AWG #4 wires, Panduit part
number LCC4-14AWH-L or equivalent). The power supply ground studs, located beside the
terminal block.
For 6000 W power supplies, use fine-stranded copper conductors rated for 90-degrees Celsius
for North American installations.
The 6000 W DC-input power supply provides voltages of 2800 W, 4500 W, or 6000 W. Select
2800 W by wiring any two positive (+)/negative (-) terminal pairs in any sequence. Select
4500 W by wiring any three positive (+)/negative (-) terminal pairs in any sequence. Select
6000 W by wiring all four terminals. The Cisco IOS software detects the wired inputs and sets
the proper system power.
If you are wiring for 2800 W for a single power supply, proceed to Step 7; if you are wiring
2800 W for a redundant power supply, proceed to Step 7 and then Step 10. In either case, proceed
to step 14 upon completion.
If you are wiring for 4500 W for a single power supply, proceed to Step 8; if you are wiring
4500 W for a redundant power supply, proceed to Step 8 and then Step 11. In either case, proceed
to step 14 upon completion.
If you are wiring for 6000 W for a single power supply, proceed to Step 9; if you are wiring
6000 W for a redundant power supply, proceed to Step 9 and then Step 12. In either case, proceed
to step 14 upon completion.
