6.5 Replacing a Power Supply Module
CAUTION: Unplug the power before removing power supply modules.
To replace a power supply module, follow these steps:
1. Follow proper ESD procedures and ensure that you have grounded yourself to a common
ground point in the equipment rack (i.e., through a wrist strap or other grounding device).
2. Remove the terminal block (for DC models) or power cord (for AC models). Note that
exposed power leads present a shock hazard.
3. Carefully remove the power supply module from the slot. The module should immediately
be placed in an anti-static bag if it is going to be sent back to Canoga Perkins for repair.
4. Carefully insert the replacement power supply module into the slot, being sure to align the
module so it slides along the guide rails and mates securely with the backplane.
5. Screw in the thumb screw to secure the module to the enclosure.
6. Reconnect the terminal block (for DC models) or the power cord (for AC models).
