Obtain a replacement as soon as possible.
Power Supplies
Depending on your Avid NEXIS model, the Engine or System Director Appliance has the following
number and type of power supply/cooling modules (PCMs) or power supply units (PSUs):
•
Two 764W PCMs with integrated fans—All 2U chassis
•
Four 580W PCMs with integrated fans—Avid NEXIS | E4
•
Two 2200W PSUs and five separate fans—Avid NEXIS | E5 and Avid NEXIS | E5 NL
The PCMs or PSUs are turned on when the power cord is plugged in and the power switch is on.
They operate as follows:
Chassis
Operation
Avid NEXIS | PRO,
Avid NEXIS | E2,
Avid NEXIS | E2 SSD,
System Director
Appliance
1+1 redundant configuration, meaning the system remains running even if one
PCM fails.
For maximum protection from power loss, both PCMs must be plugged in to
separate electrical circuits or separate UPS devices and turned on. With both
PCMs plugged in and turned on, the system balances its power needs between
them. If one PCM fails, the system can continue operating.
Avid NEXIS | E4
2+2 redundant configuration, meaning the system remains running even if any
two PCMs fail.
For maximum protection from power loss, each pair of PCMs must be plugged in
to separate electrical circuits or separate UPS devices (for example, two on circuit
A and two on circuit B), and all must be turned on. With all four PCMs plugged in
and turned on, the system balances its power needs among them.
Avid NEXIS | E5 and Avid
NEXIS | E5 NL
1+1 redundant configuration, meaning the system remains running even if one
PCM fails.
Engine can run with only two of the five fans.
Leave failed power supplies or fans in place until the replacement is ready to be
installed to maintain proper airflow and cooling.
