Mediant 8000
5.2 PS/DC/8K Power Supply Module
PS/DC/8K Power Supply modules convert DC input voltage (that may be between -40
and -60 VDC) into DC used for local power inside the chassis. Three PS/DC/8K Power
Supply modules are installed in the front of the chassis – below the board slots.
PS/DC/8K Power Supply modules are hot-swappable.

5.2.1 DC Input Power
DC power sources must meet the following requirements:

-48V SELV direct current power source

Power input between -40.5 and -57 VDC

Maximum allowable voltage should not exceed -60 VDC

Provide sufficient capacity for the average power consumption of Mediant 8000
chassis (see 'Electrical Requirements' on page
93)

Ensure that power supply complies with the safety requirements of CAN/CSA-
C22.2 No. 60950-00 and UL 60950, and EN 60950
