Enclosure

Enclosure
The ESU consists of a standard 19-inch rack-mountable, sheet metal enclosure.
Your shipping container contains a mounting kit to mount the switch in a standard
19-inch electronic equipment rack.
Cooling fans and air vents are located on the sides and the back panel of the
enclosure. When mounting the switch, ensure that these cooling fans and vents are
not blocked. In addition, you should allow sufficient airflow to prevent the switch
from overheating.

Power supply

The Metro ESU 1800 Power LED is located on the unit front panel. It indicates
whether the power supply is functioning properly.

Cooling fans

The Metro ESU 1800 contains three cooling fans. Two are located along the
right-side panel; the third is located on the left-side panel. One air intake vent is
located on the unit rear panel. When installing or mounting the switch in a wiring
cabinet or equipment rack, ensure that these fans and the air intake vent are not
blocked.
