Replacing a Summit X850 W AC Power Supply
The Summit 850 W AC power supplies are compatible with the Summit X650 series switches. These
switches have two bays for hot-swappable power supplies. In a switch with a redundant power
configuration, you can replace one Summit AC power supply without powering down the switch.
You need the following tools and materials to replace a Summit X850 W AC power supply:
●
Thermal protective gloves
●
AC power cord, if you will not be re-using the cord from the removed power supply
An AC power cord is not included with the Summit X650 AC power supply. You must obtain a
power supply cord that meets the requirements listed under
“Console Connector Pinouts” on page 500
.
To replace a Summit X850 W AC power supply:
1 Disconnect the AC power cord from the wall outlet and from the power supply.
2 Note the orientation of the installed power supply, and the location of the latching tab at the right of
the unit.
3 Push the latching tab toward the power supply handle and pull outward on the handle to disengage
the power supply internal connectors (see
Figure 293 ).

4 Carefully slide the power supply the rest of the way out of the switch.
CAUTION
Power supplies may become very hot during operation. Wear thermal protective gloves when you
remove a power supply from an operating switch.
NOTE
If you are not installing a replacement power supply, install a cover over the unoccupied power supply
bay. Unoccupied bays must always be covered to maintain proper system ventilation and EMI levels.
5 Verify that the replacement power supply is oriented the same way as the unit you removed.
