AC Power Connection
If your VX-MD4024 uses AC power, connect the AC power cord to the AC supply socket on the
front panel of the DSLAM (refer to Figure 1-8), and plug the cord into the external power source.
The voltage must be 100 to 240 V (±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 VX-MD4024 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.
