Installing the Redundant Power Supply (RPS)
An RPS is an external unit, enclosed in solid metal casing, with sockets to connect AC or DC-powered sources at one
end and to connect to a switch’s internal power supply on the other end. The RPS provides a low-cost, simple solution
to the problem of an inadvertent failure of the internal power supply of an Ethernet switch, which can result in the
shutdown of that switch, the devices attached to its ports, or an entire network.
Connecting the DPS-700 RPS to the Switch
The D-Link DPS-700 is the recommended RPS for the Switch. This RPS is designed to conform to the wattage
requirements of D-Link’s Ethernet and Gigabit switches and can be connected to the RPS port of the Switch using a
22-pin DC power cable. A standard, three-pronged AC power cable connects the RPS to the main power source.
CAUTION:
Do not connect the RPS to AC power before the DC power cable is connected. This might
damage the internal power supply.
ATTENTION:
Ne branchez pas le RPS sur le courant alternatif avant que le câble d'alimentation en
courant continu ne soit branché. Cela pourrait endommager l'alimentation électrique interne.
To connect the RPS to the Switch, remove the AC power cord from the AC power port of the Switch.
With a Phillips-head screwdriver, remove the RPS port cover by unscrewing the two screws that hold the RPS cover in
place.
Figure 3-11 Removing the RPS port cover
Insert one end of the 22-pin DC power cable into the RPS port on the switch and the other end into the RPS. Connect
the RPS to the main AC power source.
