Power Cord Requirements
The design of the switch is such that the power supplies are in a 2+2 redundancy.
Because there are four power supplies, this means that two power supplies must be
fully functional for the switch to be operational. Typically, line power is provided
from two sources, A and B. Configure the switch with A source feeding power
supplies 0 and 1, and B source feeding power supplies 2 and 3.
Your switch shipping kit should contain four power cords that are specific to your
country or application. The following table describes the power cords available.
Caution –
Only install and route power cabling in a matter that complies to federal,
state, and local electrical codes.
