Hello everyone,

I am doing a study of the thermal load of the data room at a company that has an Inter-Tel axxess version 4.4. It has two cabinets, each with the 550.0110 "9A power supply". My question is, does anyone have access to any data regarding either the wattage these systems consume, or better yet BTU output of these systems in a datacenter environment? I have the distinct feeling that the "9A" figure won't help figure this out, as I am guessing that is on the DC side and there are a selection of voltages. Thanks!

I've always calculated BTU based on the component wattage, as listed in the installation manual.

@DND ON - I would love to do so, but I do not have a copy of the installation manual. Can you by chance point me toward an online copy, or if you happen to have it handy, perhaps post or e-mail the matrix? Thank you!

The power requirements (in amps at 24 VDC) for each card are as follows:

DKSC-8 .64
DKSC-16 1.28
SLC-8 .75
SLC-16 .40
T1C .40
T1/E1/PRI .20
LSC or LGC .15
LSC-D or LGC-D .30
OPC .30
IPRC .34
IPRC-D .48

The CPC and EVMC are not specified, but the manual refers to 6 amps at 5VDC, so I’ve used that number.

Thank you. This is very helpful!
