1.2.4 Power and Ground Connections

AC Power Connection
If your VC-2402 uses AC power, connect the AC power cord to the AC supply
socket on the front panel of the DSLAM, and plug the cord into the external power
source. The voltage must be 100 to 240 VAC (±10% tolerance).
DC Power Connection
The DC power interface is a 5-pin terminal block with polarity signs on the front
panel of the DSLAM.
The VC-2402-48 can be powered from two –48V DC power supply. The DC power
connector is a 5P terminal block; 2P is for accommodating one DC power input
and other 2P is for accommodating another DC power input. The center pin of the
terminal block is FGND. The DC power should be connected to a well-fused power
supply.
After completing chassis installation, please apply power to the fused power
distribution panel feeding the chassis. When using a DC voltmeter, please check for
proper voltage: -60V ~ -36V DC, and make sure that the polarity is correct.
Ensure that all power sources to the chassis (power distribution
panel) are turned off during the connection.
Warning
It is recommended that the -48VDC power be supplied directly and
independently by a power feeding system and also avoid having a
parallel or mutual connection with other -48VDC power supplier of
telecom equipment. This is to guarantee our products against inter-

ferences by other equipment while they are working.
