Mitel MIVOICE OFFICE 250, Installation And Administration Manual

Page: 91 / 585

Specifications
63
• The UPS unit must be plugged into an isolated, dedicated circuit providing required voltage,
current, and grounding specifications.
• The power rating of the UPS unit must exceed the combined power ratings of all the equipment
the UPS supports. Table 4 provides an example of the wattage ratings in relation to the server
equipment used. This information applies only to Mitel equipment.
Component systems having power supplies include the MiVoice Office 250 server, Digital Expansion
Interface DEI(s), and the external voice processing systems. The systems plug into the battery
back-up unit, which
must
be plugged-in to an isolated, dedicated circuit having the power
specifications identified in “Power Supply” on page 1-61 .
Mitel recommends installing a backup power supply unit having the following characteristics:
• Sine wave output
• Transfer time of less than 20 msec
• Low AC line transfer voltage, or cutoff circuit, of 100 VAC, minimum
The ampere-hour rating of the battery determines the system back-up time. Also, even if the power
supply unit possesses the specifications listed in the preceding paragraph, it cannot be guaranteed
that it will work properly with the Mitel system.
UPS Monitoring
For correct operation, the UPS Monitoring feature requires compatible hardware and software, as
described in the following sections. For an expanded description of the UPS Monitoring feature and
settings associated with UPS Monitoring, refer to the
MiVoice Office 250 Features and Programming
Guide
. For installation instructions, see “Equipment to Support UPS Monitoring” on page 1-148 .
Compatible UPS Units
Three commercial UPS units were tested against the Release 2.2 software and passed UPS
Monitor-compliance testing for use with the MiVoice Office 250.
Monitoring capabilities of the following UPS units were found compatible at that time with the UPS
Monitoring feature:
• APC Smart-UPS® series (Universal Serial Bus [USB] connection)
• MGE Pulsar Evolution series (USB connection)
• ONEAC ON® Series® in advanced interface mode (To connect, you must use the USB cable
provided by the manufacturer.)
