Cooling; Ethernet Switch - Avaya Media Processing Server 1000 Hardware Installation And Maintenance

The DC circuit breaker provides breaker protection at the equipment interface. The output of the
circuit breaker panel connects to the input of the fuse panel. The input of the circuit breaker
connects to the DC PDU.

The position of the circuit breaker and fuse panel within the cabinet is dependant on system
configuration. Circuit breaker and fuse panels can be installed at the top or bottom of the cabinet,
however the most common location is at the top.

Cooling

An MPS processor cabinet with 24 servers can produce a high amount of heat. Each server can
produce 750 BTU/Hr, this equals a total of 18,000 BTU/Hr for the servers alone, plus the combined
output of all other devices. Therefore, the cabinet is equipped with special doors and cooling fans.
The front is a ventilated door, and the back door has six 6-inch fans to remove the air from the
cabinet. The fans are wired as two separate circuits, one containing two fans and one containing
four.

Ethernet Switch

An Ethernet switch is used to provide connectivity between the internal cabinet devices. The
standard setup is as a private LAN and is not normally incorporated as part of a Avaya server
subnet (formerly named CLAN). MPS 1000 supports Ethernet Switch ERS 4850GTS.
Note:
Refer to your System Definition Package (SDP) for the internal LAN configuration of your
system.
