Power Supply of BES-53248 Series Switch
Equipped with two supply modules, the switch can operate with either one or two
power supply modules. If the switch uses two power supply modules, you can hot-swap
one of the PSU during the operations.
There are two types of PSU. Each plug retainer is color-coded to indicate its airflow
direction.
•
Red: indicates front-to-back airflow.
•
Blue: indicates back-to-front airflow.
The AC power connector is a standard three-pronged connector. The switch automatically
adjusts its power setting to any supply voltage in the range from 100~240 VAC at
50~60 Hz.
NOTE:
•
Verify that each module has the same airflow direction. Make sure the switch runs
with all of its power supply and fan tray modules taking in air from a cold aisle
and exhausting air to the hot aisle.
