Summit 350 W AC Power Supplies
Summit 350 W AC power supplies are available in the following models:
• 350 W AC PSU-FB (models XN-ACPWR-350W-FB and 10953)—AC power supply with front-to-back
ventilation airflow
• 350 W AC PSU-BF (Model 10954)—AC power supply with back-to-front ventilation airflow
Both power supplies are compatible with X460-G2 PoE switch models that have the same airflow
direction as the power supply.
The Summit 350 W AC PSU-FB (models XN-ACPWR-350W-FB and 10953) is compatible with the
X465-24S, X465-24XE, and X465-48T switch models that have the same airflow direction as the power
supply.
These power supplies have a keyed power inlet (C16) that requires a notched (C15) power cord.
The Summit 350 W AC power supplies have the status LEDs listed in Table 49.

• 550 W DC PSU-FB (Part number 10926)—DC power supply with front-to-back ventilation airflow
• 550 W AC PSU-BF (Part number 10927)—AC power supply with back-to-front ventilation airflow
• 550 W DC PSU-BF (Part number 10928)—DC power supply with back-to-front ventilation airflow
These power supplies are compatible with the following switch models:
• X670-G2 switches (all 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.
