Installation Guide, Second Edition - HP Integrity cx2620

NOTE: A hot-swappable device does not require interaction with the operating system before
the device is removed from or installed into the server. If the second power supply is functioning
correctly, you can power off and remove a power supply with no effect on server operations.
Installing a Hot-Swappable Power Supply
You can install a power supply while the server is installed in a rack.
To install a hot-swappable power supply, follow these steps:
1. If rack-mounted, you may need to extend a slide-mounted server out from the rack for better
access. If necessary, slide the server out to the fully extended position.
2. Orient the power supply such that the securing screws are aligned with the corresponding
holes in the server chassis. Gently push the power supply into position.

3. When the power supply is fully inserted into the server chassis, tighten the two mounting
screws to secure the power supply in place.
4. Press up on the two lower tabs on the terminal barrier strip cover to snap off the cover.
WARNING! Always check that the power cable is not connected to a power source before
attempting to connect the power cable to power supply terminals. Failure to observe this
warning can result in injury.
5. Connect the power cable leads to the power supply terminals (Figure 1-7).
