D-Link DPS-800 2 slot Redundant Power Supply Chassis
D-Link Logo

2 Slot Rack-mount Chassis for select D-Link DPS Redundant Power Supplies

DPS-800 2-Slot Redundant Power Supply Unit Open Chassis

The tandem of D-Link’s new Enterprise Gigabit switches and DPS Series of Modular Redundant Power Supplies (RPSU) enables today’s business networks with unmatched flexibility, performance, scalability, and availability. The modular design of the DPS Series of RPSUs enables companies to selectively and cost effectively deploy higher availability configurations precisely when and where they are needed most. When paired with a supported D-Link switch, the DPS-200, and DPS-500 provide uninterrupted fail-over, in the unlikely event of a mechanical power supply failure. The system integration between D-Link’s Managed Layer 2 switches, Layer 3 switches, and RPSU system, provide customers with the fundamental building blocks to create economical and scalable networks without having to sacrifice network performance and availability.

Guaranteed Power Protection Protects your critical data and network infrastructure across your business from unsafe voltage levels and costly interruptions.






Robust Continuity The DPS-Series is housed in solid metal cases ensuring reliability in tough environments including wide temperature ranges or high traffic areas.






1+1 Power Capabilities When cascading the DPS-700 with a device’s internal power supply, the power system can provide an additional power budget to the device.






Redundant Power Backup Each D-Link RPS is equipped with an integrated detection circuit that continuously monitors the switch’s 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 going down due to the failure of a single 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 an AC power source from 90 V AC to 264 V AC, 47 Hz to 63 Hz through a standard AC power cable.

D-Link DEM-CB100QXS 1M 40G QSFP+ to QSFP+ Stacking Cable
D-Link Logo
Direct Attach

40G QSFP+ to QSFP+ 1 m Direct Attach Stacking Cable

The 40G Passive QSFP+ Direct Attach Cable is a high performance, high bandwidth and cost-effective connection solution that supports 40G Gigabit Ethernet. The 40G Passive QSFP+ Direct Attach Cable is designed to support high-density connections for switches with 40G interface, much faster than SFP+.









Features QSFP+ (Quad Enhanced Small Form-factor Pluggable)
40 Gbps Gigabit Ethernet
• Fully Compliant with the following standards - SFP MSA (Multi-Source Agreement), EIA 364, UL 94, SFF-8436, SFF-8431, EIA-364-1000.01 








 






Better Performance High speeds of up to 40 Gbps and lower latency result in faster transmissions than other types of cables.






Cost-effective Solution QSFP+ connector on cable replaces four standard SFP+ cable assemblies, ensuring higher port density and cost savings.






Energy Efficiency Lower power consumption and EMI emissions means savings on energy usage and expenses, and less electronic interference.






Ideal for High-Bandwidth Operations The 40G Passive QSFP+ Twinaxial Direct Attach Cable supports speeds of up to 40 Gbps, while having lower crosstalk and power consumption than other cables. This makes it an optimal solution for handling high bandwidth transmission within short distances such as within a rack or between racks inside energy-efficient data centers.






Quad Small Form-factor Pluggable Plus Format The D-Link 40G Passive QSFP+ Twinaxial Direct Attach Cable uses Quad Small Form-factor Pluggable Plus format (QSFP+) connectors, which integrate four transmitting and four receiving channels. The QSFP+ cable assemblies can replace four standard SFP+ cable assemblies, resulting in higher port density, cost efficiency, and a reduction in power savings compared to standard SFP+.






Save on Costs The D-Link 40G Passive QSFP+ Twinaxial Direct Attach Cable features QSFP+ connectors on both ends, thus eliminating the need for expensive QSFP+ transceivers. This makes it more cost-effective than fiber cables which must use QSFP+ transceivers.

D-Link DPS-500A - Redundant power supply (RPS)
D-Link Logo

The DPS-500A redundant power supply (RPS) are designed to conform to the wattage requirements of D-Link's Ethernet and Gigabit switches. It is an external RPS unit enclosed in solid metal cases with sockets to connect to an AC power sources on one end and to connect to a switch's internal power supply on the other end.

It provides a low-cost, 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 maximise the power availability of the switching device.

Redundant Power Backup

Each D-Link RPS is equipped with an integrated detection circuit that continuously monitors the switch's 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 going down due to failure of a single 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.

Modular Redundant Power Supplies

The DPS-500A is a modular redundant power supply which can be installed as independent power supply units or placed inside a DPS-800 Rack-mount chassis. The chassis are designed for mounting in a standard 19-inch equipment rack. Multiple power supplies can be placed inside a chassis, from which they can connect to the switches mounted in the same rack.

Rack-Mount Chassis

The DPS-800 chassis can accommodate up to two DPS-200A modules to an equipment rack. Using a chassis, users can save space while allowing for clean cabling. All redundant power supply units installed in the chassis connect directly to their power sources, and they are hot-swappable.
