DMS-3130 Series Layer 3 Stackable Managed Switch Hardware Installation Guide
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.
CAUTION: This unit has redundant power sources. Please disconnect all the power cords before
servicing.
DPS-500A Series Redundant Power Supply Unit
This RPS (DPS-500A) 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. Note this section only applies to DMS-3130-
30TS.
Remove the AC power cord from the AC power port of the Switch. Insert one end of the 14-pin DC power cable into
the port on the switch and the other end into the RPS. Using a standard AC power cable, connect the RPS to the main
AC power source. A green LED on the front of the RPS will glow to indicate a successful connection. Reconnect the
AC power cord to the AC power port of the Switch. The RPS LED indicator on the front panel of the Switch will
indicate that an RPS is present and now in operation. No software configuration is required.
NOTE: See the DPS-500A/DPS-500DC documentation for more information.
CAUTION: This equipment is to be connected only to PoE networks without routing to the outside
plant.
