9 Connecting Power
9.1 System Power Consumption
The maximum power consumption of the S9705-48D is 1466 watts. It is recommended
that enough power be reserved from the power distribution system in order to support the
proper function of the S9705-48D. Ensure that both PSUs have been properly installed before
powering up the switch, as the S9705-48D is designed to support 1 + 1 power redundancy
9.2 Connecting the AC Version PSU
9.2.1 Attaching the AC Power Cord
Locate the AC inlet connector on the PSU and plug the AC power cable (250Vac 15A,
IEC60320 C19) into the AC inlet connector.
9.2.2 Feeding AC Power
The PSU will immediately output 12V & 5VSB to the system with a 220V, AC power source.
The PSU has a built-in 15 amperes, fast acting fuse based on the PSU maximum capacity,
which will act as a second tier system protection in case the power distribution unit's fuse is
not functioning.
If only a 110V AC power source is available, the S9705-48D can still be powered with
both PSUs providing 1000 watts each for a total output of 2000 watts. However, in this
case, if one PSU stops functioning, the power output would be inefficient to sustain the
Note
switch's operation.
9.3 Connecting the DC Version PSU
9.3.1 Before Attaching the DC Power Cable
The UL 1015, 6 AWG DC power cable (not provided) must be attached to a two-hole lug
before connecting to the PSU. The following instructions are for connecting the DC Power
Cable to the lug:
1. Strip the insulation from a DC Power Cable, leaving 0.5" +/-0.02" (12.7mm +/-0.5mm) of
exposed cable.
2. Insert the exposed DC power cable into the heat shrink tubing, the length of heat shrink
tubing should not less than 38.5mm.
3. Insert the exposed DC power cable all the way into the hollow tube of the lug (provided
with switch package contents).
4. Using a crimping tool, firmly secure the DC power cable to the lug. It is recommended to
not crimp exceeding the lines indicated on the lug, which is also depicted as the cross-
section area in the picture on the below.
