Replacing a Summit 450 W or 550 W DC Power Supply

The Summit 550 W DC power supplies are compatible only with Summit X670 series switches. The 550
W DC power supplies are available in versions for switches with either front-to-back or back-to-front
airflow.
The Summit X480 and X670 switches have two bays for hot-swappable power supplies. In a redundant
power configuration, you can replace one Summit X480 DC power supply without powering down the
switch.
You need the following tools and materials to replace a Summit 450 W DC power supply:
•
#1 Phillips screwdriver
•
Torque screwdriver and wrench or torque driver with attachments for tightening screws and nuts
•
Thermal protective gloves (required for removal of a power supply)
Note
You cannot combine 450 W power supplies and 550 W power supplies in the same Summit
X670 series switch.
