To remove a DC power supply:
1. Switch off the dedicated customer-site circuit breaker for the power supply being removed. Follow
your site's procedures for ESD.
2. Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance
that the cables might become active during the removal process.
3. Verify that the status LED on the power supply is not lit.
4. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on
the chassis.
5. Using a socket nutdriver, remove the nut from each of the DC power terminals (see
Figure 42 on page 131).
6. Remove the cable lugs from the terminals.
7. Carefully move the power cables out of the way.
8. Press the latch located on the left side of the DC power supply, to release it from the chassis.
9. Pull the power supply straight out of the chassis (see
Figure 42: Disconnecting the DC Power Cables
Figure 43 on page 132).
