•
Power failure
•
Ethernet port link break
•
Ping failure
•
Super ring failure
You can configure the fault relay settings in the ES7528 web user interface (

Attach the brackets to the ES7528 by using the screws provided in the rack mounting kit.
2.
Mount the ES7528 in a 19-inch rack by using the four rack-mounting screws provided in the kit.

Ground the chassis to earth ground
Temperature: Verify that the rack environment temperature conforms to the
specified operating temperature range. If necessary, refer to the Comtrol web site for
operating temperature ranges.
Mechanical Loading: Do not place any equipment on top of the switch. In a high
vibration environment, additional rack mounting protection is necessary.
Grounding: Rack-mounted equipment should be properly grounded. On the back
panel of the ES7528, there is one earth ground screw. Loosen the earth ground screw
with a screwdriver; then tighten the screw after earth ground wire is connected.
