IPSI support for system maintenance
A TN2312BP IPSI placed in a G650 with a carrier address set to A acts as the serial bus master.
A TN2312BP IPSI can only be placed in a G650 with a carrier address set to A or B. Only a
TN2312BP IPSI in a G650 with a carrier address set to A can function as an serial bus master.
The TN2312BP IPSI also provides environmental maintenance for the G650. This includes:
● Power supply, cabinet, and ring generator maintenance
● External device alarm detection
● Emergency transfer control
● Customer-provided alarm device control
The TN2312BP IPSI and the 655A power supply provide the following information to the G650:
● Environment maintenance
- Inlet temperature of the G650
- Exhaust temperature of G650
- Hot Spot temperature status
- Voltage, +5, -5, or -48
- Fan speed
- Fan alarm
- Ring status
- Ring control
- Ringer Setting
- Ring Detection
- Input Power, AC or DC
● External device alarm detection
The external device alarm detection uses two external leads. External devices such as an
uninterruptible power supply (UPS) or voice messaging system can use these leads to
generate alarms. The external device uses the Avaya Communication Manager alarm
reporting capability. Ground potential on either of these leads results in an alarm being
generated. You can administer the alarm level, product ID, alternate name, and alarm
description for each lead. The alarm levels are major, minor, and warning.
● Emergency transfer control
Emergency transfer control provides -48 VDC to operate an external emergency transfer
panel. The Communication Manager controls the state of the emergency transfer. When the
emergency transfer is set to other than auto, an alarm is generated.
