D-Link DPS-800 Quick Installation Guide - Page 10

Introduction Installation of the RPS A redundant power supply provides a low-cost, simple solution to the equally simple yet vexing problem of internal power supply failure, which can result in the shutdown of a single switching device or an entire network. The single RPS DPS-200, 300, 500, and 500DC can be installed to the standard rack via the RPS rack DPS-800 and DPS-900. DPS-900 is a standard-size rack mount (5U in height) designed to hold up to 8 redundant power supplies. The DPS-800 is also a standard-size rack mount With a redundant power supply connected, an integrated detection circuit continuously monitors the switch's internal power supply. In the event of a power interruption, the (1.25U in height) designed to hold up to 2 redundant power supplies. Installed RPS units can be DPS-200s, DPS-300s, DPS-500s, DPS-500DCs, or a combination of the above. redundant power supply is immediately triggered so that the switch and connected devices can continue providing NOTE: The DPS-500DC can only be inserted service. into a DPS-800 This results in a more reliable network infrastructure and protects the network from a single failure of a network device power supply. Description Installing a DPS-600/700 in a standard electronics rack The DPS-200, DPS-300, DPS-500, DPS-500DC and DPS- 600 are redundant power supply units designed to conform to the wattage requirements of the switches being supported. DPS-200 operates at 60 watts, DPS-300 operates at 90 watts, DPS-500/500DC at 140 watts, and DPS-600 at 500watts. Inserting a single RPS into a DPS800 RPS rack The DPS-200, DPS-300, DPS-500, DPS-500DC, and DPS- 600 can connect to the master switch using a 14-pin DC power cable. Similarly, the DPS-700 uses a 22-pin DC power cable. A standard, three-pronged AC power cable connects the redundant power supply to the main power source.
