Electrical Requirements
105
If you do not create a separately derived power system, make sure the power outlets are from the same distribution
panel. This helps prevent the occurrence of ground loops that can be caused by plugging equipment into power
sources with different ground potentials.
If you run more than one power line because you have more than one UPS, make sure the power lines come from
the same distribution panel.
w
Have all the electrical work at your site done by a licensed electrician. All the electrical changes must meet
country, state, and local electrical codes.
As you choose the location for your Avid shared storage hardware, keep these electrical requirements in mind:
• Make sure there is adequate, dedicated power for the UPSs that are part of your Avid shared storage
workgroup.
n
Avid recommends the use of UPSs, appropriately sized for your Avid shared storage workgroup, or conditioned
power in your computer room environment. This provides protection against sudden power surges or losses that
could cause you to lose files or experience data corruption.
• Make sure your location is away from major electrical equipment such as motors, air conditioners, or
elevators.
• Make sure the location is not subject to electrostatic buildup.
• Plug only your Avid hardware into the power strips. Do not plug in coffee makers, radios, lights, or other
non-Avid devices.
The following table shows the electrical specifications for the Avid qualified and approved switches. Make sure
your site meets these specifications.

There are three load balancing power supplies in the ISIS | 7500 Engine. When powered up, they share the load
between all three supplies for a total of 1200W.
