Key Features
Reduce the Impact of an Internal Supply Failure
An internal switch power-supply fault can disconnect every endpoint behind that switch. A supported redundant supply provides an additional power path, allowing the power system to respond when the internal supply fails. The switch and external supply must be a manufacturer-approved combination.
Match the Supply to the Exact Switch
The DPS-500A is intended for specific supported D-Link switch models and hardware revisions. Match the power requirements, RPS connector and required cable before installation. A similar connector or the same brand name alone is not enough to establish compatibility.
Plan the Available Power
The rated output is 140W for the supported redundant-power application. This is not a general-purpose desktop power adapter. Check the switch’s documented RPS requirement and keep the connection within the manufacturer’s supported configuration.
Keep the Rack Organised
The compact metal enclosure can be used separately or installed in the optional DPS-800 chassis. The chassis holds up to two compatible modules and is purchased separately. Leave clearance for cooling and route the DC cable without strain.
Specify the Correct Connection
The normal offer includes a 1 m DC cable. Some supported switch families require a different cable, so confirm the exact host and cable arrangement before ordering. Do not assume that every supported switch uses the same lead or that an optional extension is included.
Separate Redundancy From Battery Backup
This supply depends on AC mains power and does not contain a battery. It helps address an internal supply fault but does not keep the network running through a loss of all AC sources. Use a suitably sized UPS and a tested power design where mains-outage continuity is required.
Summary
The DPS-500A adds a planned redundant-power path to a supported D-Link switching installation. Confirm the switch revision, required cable and complete power design so redundancy supports the intended network availability.
Frequently Asked Questions
Is This a Battery UPS?
No. It is an AC-powered redundant supply without a backup battery. A suitable UPS is separate if you need continuity during a mains outage.
Will It Work With Every D-Link Switch?
No. Compatibility is specific to the switch model, hardware revision and RPS connection. Check the supported combination and required cable before ordering.
Does It Increase the PoE Budget?
DPS-500A is a 140W redundant supply for supported switches. It should not be treated as a general PoE budget upgrade.
Is the Connection Cable Included?
The normal offer includes a 1 m DC connection cable. Some switch families require another cable, purchased separately; confirm the exact host before ordering.
How Is It Mounted?
Use it as a standalone module or in the optional two-slot DPS-800 rack chassis. The chassis is separate.
