D-Link Redundant Power Supply DPS-500A
Overview
- Keeps your switch online in case of power supply failure.
- Can be installed as standalone module, or in 19-inch rack mountable
chassis
- Solid metal housing
- LED status indicators
- 90 to 264 Volts, 47 to 63Hz AC input range
Integrated Detection Circuit
Each D-Link RPS is equipped with an integrated detection circuit that
continuously monitors the switching devices internal power supply. In the event
of a power interruption, the redundant power supply is immediately triggered so
that the LAN switch and its connected devices can continue providing service.
This results in a more reliable network infrastructure and protects the network
from a single failure of a network device power supply.
Easy and Flexible Deployment
Deployment of a DPS series device does not require any change in the
configuration of the LAN switch. Each RPS is equipped with a universal internal
power supply and can be connected to any AC power source from 90 V AC to 264 V
AC, 47 Hz to 63 Hz through a standard AC power cable
Affordable Redundant Power Backup
The DPS-200A, DPS-500A, and DPS-500DC redundant power supplies (RPS) are
designed to conform to the wattage requirements of D-Links Ethernet and Gigabit
switches. They are external RPS units enclosed in solid metal cases with sockets
for AC or DC power sources on one end, and connect to a switchs internal power
supply on the other end. They provide a n affordable, 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. Supporting full output power for the switch,
these redundant power supplies can maximize the power availability of the
switching device.
