Power Connections

The switch includes integrated hot-swap power supplies which support up to 6 load-shar-
ing 1000W. The slots for the power supply units (PSUs) are on the spine side. The left
side has odd numbered PSUs and the right side has even numbered PSUs. Each PSU has
a dedicated AC inlet. This design enables the optional use of separate main and backup
AC feeds. The input voltage is Autorange, 100-240 VAC, 50Hz or 60Hz. The output
voltage for the PSUs is 48V. The power cords should be standard 3-wire AC power cords
including a safety ground.
