Multiport aggregate device power and grounding
requirements
The multiport aggregate device contains two dc power supplies. When both
power supplies are operational, they share power consumption for the device.
If one of the power supplies fails, the remaining power supply provides power
for the device.
The dc power source must be within the range of -36 to -72 V dc. Maximum
power consumption is 20 Watts. The dc power feeds into the system must be
protected with an external circuit breaker or fuse, with appropriate voltage
ratings and regulatory approvals. The disconnect device must be external to
the cabinet or rack and reside in the same room.
You must supply your own power cables. Power cables must be properly
grounded.
