Installing the Redundant Power Supply (RPS)
The Redundant Power Supply (RPS) is designed to conform to the wattage requirements of D-
Link’s Ethernet and
Gigabit switches. It is an external RPS unit enclosed in solid metal case with sockets to connect AC or DC power
sources on 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.
CAUTION:
Do not connect the RPS to AC power before the DC power cable is connected. This might
damage the internal power supply.
CAUTION:
Leave at least 15 cm (6 inches) of space at the rear of the Switch when an RPS is installed
to prevent cable damage.
DPS-500 Series Redundant Power Supply Unit
This RPS (
DPS-500A
and
DPS-500DC
)
can be connected to the Switch’s RPS port using a 14
-pin DC power cable. A
standard, three-pronged AC power cable connects the RPS to the main power source.
