Installation Guide

The power supply must have the same airflow direction (front-to-back or back-to-front) as the switch
with which it is being used. In a redundant power configuration, the airflow direction must be the same
for both power supplies, and it must match the airflow direction of the fans in the switch.
The Summit 550 W power supplies (AC and DC) have the status LEDs listed in Table 86.
