These power supplies are compatible with the following switch models:
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 Summit 550 W Power Supply LED Status Indications.
