Customer-provided cabinet requirements
If the Avaya MAS and MSS are to be installed in a rack-mount
configuration, the customer-provided cabinet must meet the following
requirements:
! The cabinet must contain a 4-post rack to support the weight of
the server.
! The cabinet must be secured to the floor before attempting to
mount any units.
! The sliding rails and extender brackets provided with each server
are designed for mounting in cabinets 22.5 to 32 inches in depth.
! The cabinet height must accommodate the number of units to be
mounted. It may also need to hold the MAS modems, UPS, and
optional equipment such as the KVM switch.
Power requirements
Table B-3 lists the power requirements for the S3400-family servers. The
AC power supply source must be a single phase 3-conductor (line,
neutral, and ground), with a 15 A circuit breaker for 100-127 Vac
installations or a 10 A circuit breaker for 200-240 Vac installations.
Consider the server connection to a branch circuit with regard to overload
or overcurrent protection. Verify the system ratings to ensure that,
together with other equipment connected to the same branch circuit, an
overcurrent or overload condition does not exist.
