Installation Instructions

Note:
Do not connect an AC and DC power supply in the same chassis. Load sharing may be
affected.
Important:
You can hot swap power supplies while the switch is operational. One power supply is
required for continued switch operation. PoE+ load reductions can occur if you remove
one power supply while the switch is operating with dual power supplies.
Power supply power specifications for the VSP 4450GSX series
switches
The VSP 4450GSX series switches support two external field replaceable AC and DC power
supplies. One power supply ships with the chassis. You can install a secondary power supply to
provide redundancy, load sharing, and to add Power over Ethernet Plus (PoE+) power budget on
PWR+ models.
AC power supply power specifications
The VSP 4450GSX-PWR+, including the TAA compliant version, supports dual 54V 1000W Power
over Ethernet Plus (PoE+) AC power supplies.
Important:
Ensure that you use only 1000W power supplies (both primary and secondary) on VSP 4000
PWR+ models.

Connector
The 1000W AC power supply uses an IEC 60320 C16 AC power cord connector. The AC power
cord is in close proximity to the hot air exhaust, and supports high operating temperatures.
