I am wondering about Aux pwr from an IPSI/SIPI. I know you can get one pair of Aux pwr to support the console. I tried to hook up a second lead for a Univ 909, but it would not work. I have 47.8 volts on pairs 1,2 and 4, but am only able to make something work on pair 1 (bl)

If I put the Univ 909 on the first pair it worked, and if I moved the console to anoher pair it did not. Can the IPSI/SIPI only support one pair even though there is voltage on the other pairs?

Any help is appreciated. Thanks!

the DB9 is not suppose to provide power for anything other than an emergency transfer panel (ie. an 808A), the out current is insufficient.
pins 1&2 give -48V for emergency transfer
pins 4&5 are dry contacts for alarm bell light or indicator
pins 6&7 are for UPS major alarm
pins 8&3 are for UPS minor alarm

1. Connect 1 major (Brown-White and White-Brown) and 1 minor (Orange-White and
White-Orange) alarm input pair to the trunk/auxiliary field from the TN2312BP Adapter DB9
alarm connector. Alarms can be generated on adjunct equipment, sent to the Avaya
media gateway, and recorded and reported as "external alarms." The adjunct equipment
must provide an isolated contact closure across the alarm leads provided by the Avaya
media gateway. The contact must be rated at a minimum of 60 VDC with a current carrying
capacity of 5 mA minimum.
2. Connect an external alarm output (Green-White and White-Green).
3. Note which device connects to which alarm and give this information to your Avaya
representative for troubleshooting purposes.

Thanks a lot, that confirms what I found in the field. Now I know exactly what they are for. I called Avaya, but they could not find anything on the IPSI/SIPI (so that person said).
