Power
Two versions of the Hotwire 8610 DSLAM chassis are available: an
AC power version and a DC power version.
The AC version can be connected to a DC source to provide power AC.
With the DC version, two separate DC sources may be employed to
provide power redundancy.
The AC version accepts AC power (100–250V, 50–60 Hz) and converts
it to DC power. The maximum current draw is 2.5 amps, or 75 watts @
100 VAC. At maximum configuration with 3 DSL cards, the system will
not exceed 125 watts of power dissipation. The current draw with no
cards is 20 watts.
The Hotwire 8610 DSLAM chassis DC version operates from a DC
–48 VDC power supply (–40.0 to – 60.0 VDC). The maximum current
draw is 2 amps. At maximum configuration with 3 DSL cards, the
system will not exceed 100 watts of power dissipation.
Each power version distributes –48 VDC power from the power source
to individual cards via the backplane.
Grounding
A ground lug is located on the right rear of the Hotwire 8610 DSLAM. It
accepts 14 AWG wire.
A noninsulated banana jack is located at the left front of the
8610 DSLAM providing a ground for the ESD wrist strap plug.
Cooling and
Air Handling
The internal fan module is installed in the chassis to provide cooling.
A built-in feature shuts off power to the circuit cards if a chassis
overheats because of fan failure. If the temperature in the chassis
reaches 70
°
C, power to the cards in the chassis is turned off
automatically. Power is turned on when the temperature drops below
60
°
C.
