DPS-500
Redundant Power Supply
Chassis-based Redundant Power Supply
Supported Devices
Power Supplies Stand-alone or Installed in Chassis
The DPS-200, DPS-300 and DPS-500 are redundant power supply designed for use with D-Link LAN switches. Each power
supply connects to a switch to provide redundant backup power to the built-in power supply units inside the switch. These RPS can
operate as stand-alone redundant power supply units, but they can also be installed in a DPS-800 or DPS-900 chassis. The DPS-
900 is an 8-slot standard rack-mount size chassis designed to accommodate up to 8 RPS. Using a DPS-900, you can deploy up to
8 redundant power supply units in a standard equipment rack to support a stack of 8 stackable D-Link switches mounted in the
same rack.
- DPS-200 redundant power supply: provides up to 60 watts output power.
- DPS-500 redundant power supply: provides up to 140 watts output power.
- DPS-800 2-slot chassis: allows 2 RPS to be deployed in a standard equipment rack.
- DPS-900 8-slot chassis: allows up to 8 RPS to be deployed in a standard equipment rack.
The DPS-200 redundant power supply supports the following D-Link devices:
DES-3326SR L3 stackable switch
DES-3350SR L3 stackable switch
The DPS-500 redundant power supply supports the following D-Link devices:
DGS-3224SR L2 stackable switch
DGS-3324SR L3 stackable switch
DGS-3324SRi L3 stackable switch
DPS-800 Chassis
This chassis is designed to hold 2 RPS for use with a stack of 2 stackable switches. The DPS-800 can be installed in a 19-inch
standard equipment rack.
DPS-900 Chassis
The DPS-900 is especially designed to hold 8 RPS for use with a stack of 8 stackable switches installed in an equipment rack.
Using this chassis, you can save space, while your cabling will look neat. The chassis comes with no power supply of its own. All
redundant power supply units installed in this chassis will connect directly to their AC power source.
All power supply units come with their own solid metal case housing and LED status indicators. They can be used as stand-alone
power supply units, or installed in the chassis. As they are independent units, they are hot-swappable when used with the chassis.
- DPS-300 redundant power supply: provides up to 90 watts output power.
The DPS-300 redundant power supply supports the following D-Link devices:
DGS-3224TGR L2 Gigabit Switch
DGS-3212SR L2 stacking master
DGS-3312SR L3 stacking master
