Installing A Dc Power Supply - Avaya VSP 7200 Series Installing Manual

Danger:
Using power cords with a proper grounding path
Use only power cords that have a grounding path. Without a proper ground, a person who
touches the switch is in danger of receiving an electrical shock. Lack of a grounding path to the
switch can result in excessive emissions.

Installing a DC power supply

Important:
Avaya does not support installing a combination of AC-input and DC-input power supplies in the
same chassis.
The VSP 7200 Series Series supports two field-replaceable 800 W DC power supplies. One comes
with the switch and you can install a second power supply to provide redundancy and load sharing.
Both the VSP 7254XSQ (fiber switch) and the VSP 7254XTQ (copper switch) use the same DC
power supply model: EC8005001-E6 (front-to-back cooling).
There are two power supply slots (PSU1 on the left side and PSU2 on the right).
• If you only have one power supply, you can install it in either PSU1 or PSU2.
• If you install a second power supply, neither one acts as a primary power supply. The two
power supplies load share equally.
Before you begin
Remove the power cord before installing or removing the power supply.
Note:
The design of the latch mechanism that secures the power supply enforces this safety practice.
