PWR600 AC and DC Power Supplies

40
The x950 series switch supports the PWR600 AC and PWR600 DC power
supply units.
Here are power supply guidelines:
You can install either one or two power supplies in the switch.

A single power supply can power a fully equipped switch.

Installing two power supplies adds power redundancy.

You can install two PWR600 AC modules, two PWR600 DC

modules, or a combination of the PWR600 AC and PWR600 DC
modules on one switch.
The power supplies are installed in the PSU A and PSU B slots in

the rear panel of the chassis. If you are installing only one power
supply, Allied Telesis recommends installing it in PSU A slot
because that slot does not come with a blank slot cover.
The switch does not come with power supplies. They are

purchased separately.
The power supplies are field-replaceable and hot-swappable. If the

switch has two power supplies and one fails, you do not have to
power off the operational power supply to replace the failed unit.
