XMU+ Installation and Maintenance Guide rev.07 17
Meeting System Requirements
Power Requirements
Depending on the number and types of line cards installed, the large chassis XMU+ can
consume as much as 220 Watts, while the small chassis XMU+ can consume as much as
50 Watts. See Chapter 11: XMU+ Technical Specifications and Approvals for more power
consumption information.
To meet XMU+ power requirements, ensure that the necessary power sockets (AC or DC)
are available, unoccupied, and have a protective earth/ground connection.
Note: Since the AC power cord is the disconnect for the XMU+, ensure that the AC receptacle is
near the unit. See XMU+ Approvals on page 143 for more information.

Specifications and Approvals.
If the operation on a UPS is required, ensure that the appropriate UPS requirements
(power and runtime) are determined.
 The power rating must be at least that of the XMU+ system. (See Chapter 11: XMU+
Technical Specifications and Approvals for specific XMU+ system ratings).
 The amount of runtime is up to the user.
For a large chassis XMU+, the dual Power Supply cards can be used to provide a degree of
power supply diversity. For example, two AC supplies could be used, each connected to a
different branch circuit.
PBX Requirements
The functionality of the XMU+ is dependent on the type of PBX (switch) with which it is
used. See Cabling XMU+ Line Cards on page 54 for more information. Before you begin to
install the XMU+ unit, you should identify your PBX and ensure that the information is
readily available by recording it below, as well as in The XMU+ Delivery Checklist on page
21.
