power conversion module to the ON position (marked “–”).
11. Check the indicators on the power conversion module as the switch is
powered on to verify that the -48V LED indicating external power status is
on, and that the +12V LED indicating internal power conversion is on. If
not, recheck the power supply and power cable connections at the supply
source and at power conversion module.
12. If you have installed both a primary and redundant power conversion
module, verify that the LEDs on both modules are lit as indicated in the
preceding step.
CONNECTING AC POWER
When a universal AC power module is installed in the switch, external AC power
must be supplied to the module.
To connect the switch to a power source:
1. First verify that the external AC power supply can provide 100 to 240 VAC,
50-60 Hz, 2 A minimum.
2. Plug the power cable into a grounded, 3-pin, AC power source.
3. Insert the plug on the other end of the power cable directly into the
receptacle on the AC power module.
N OTE : For international use, you may need to change the AC line cord.
You must use a line cord set that has been approved for the receptacle
type in your country.
