Installing A Dc Power Supply - Avaya Virtual Services Platform 7200 Series Installation Manual

Country and Plug Specification
United Kingdom:
• BS1363 male plug with fuse
• Harmonized cord
Australia:
• AS3112-1981 male plug
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 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.
There are two power supply slots (PSU1 on the left side and PSU2 on the right).
Important:
Refer to the following part numbers to ensure that you install the correct power supplies in your
switch. Both the VSP 7254XSQ (fiber switch) and the VSP 7254XTQ (copper switch) use the
same DC power supply models:
• EC720500B-E6 — 800 W DC POWER SUPPLY BACK2FRONT COOLING
• EC8005001-E6 — 800 W DC POWER SUPPLY FRONT2BACK COOLING
• 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.
