Replacing a Summit 550 W DC Power Supply

Summit 550 W power supply units (PSUs) are available with either front-to-back or back-to-front airflow. If you install two PSUs, both must have the same airflow direction.

Note

You cannot combine power supplies of different wattages in the same switch.

You need the following tools and materials to replace a 550 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)
