Q
What is a D-Link core switch power supply?
A
A D-Link core switch power supply is a modular, high-efficiency unit that delivers reliable DC power to D-Link chassis switches, ensuring optimal uptime and network performance.
Q
Which D-Link core switch models are compatible with these power supplies?
A
D-Link core switch power supplies are compatible with DXS-3600, DGS-3627, DGS-3630, and other D-Link chassis series that support field-replaceable power modules.
Q
How do I install the power supply unit in a D-Link core switch?
A
To install, power down the chassis, slide the PSU into an empty bay until it clicks, secure the latch, then reconnect AC power and power on the switch.
Q
Are D-Link core switch power supplies hot-swappable?
A
Yes, D-Link core switch power supplies are hot-swappable, allowing you to remove or replace modules without interrupting network traffic when redundancy is enabled.
Q
What is the wattage rating of D-Link core switch power supplies?
A
D-Link offers 650 W, 1200 W and 1600 W power supply modules to accommodate various chassis sizes and power demands.
Q
How do I choose the right power supply capacity for my D-Link core switch?
A
Calculate total port and PoE load, then select a PSU with at least 20% headroom above your maximum power requirement to ensure stability and future scalability.
Q
Can I use third-party power supplies in D-Link core switches?
A
D-Link recommends only OEM power supplies to maintain warranty coverage, ensure full compatibility, and achieve certified safety and performance standards.
Q
How do I troubleshoot a failed power supply on my D-Link core switch?
A
Check the PSU LED status, verify AC input and fuse integrity, reseat the module, and consult switch logs via the CLI for specific error codes.
Q
What LED indicators show a power supply failure on a D-Link core switch?
A
A solid amber or unlit PSU status LED indicates a failure; a green LED signifies normal operation, while a blinking amber LED denotes a warning.
Q
Is redundancy supported on D-Link core switch power supplies?
A
Yes, D-Link chassis switches support power redundancy; installing two or more identical PSUs ensures uninterrupted operation in case of module failure.
Q
How do I replace a redundant power supply in a D-Link core switch?
A
Hot-swap the failed PSU by pulling the latch, removing the module, inserting a new identical unit, and confirming the green LED status for redundancy.
Q
What warranty covers D-Link core switch power supplies?
A
D-Link core switch power supplies come with a limited lifetime warranty and free advanced replacement for the duration of the switch’s warranty period.
Q
What input voltage range do D-Link core switch power supplies support?
A
D-Link PSUs accept 100–240 VAC, 50–60 Hz auto-sensing input to accommodate global power standards without manual configuration.
Q
How can I monitor power supply health on a D-Link core switch?
A
Use the switch’s CLI or web GUI to view PSU status, input/output voltage, and temperature metrics under the System → Power Supply menu.
Q
What is the MTBF of D-Link core switch power supplies?
A
D-Link PSUs feature an MTBF (Mean Time Between Failures) exceeding 100,000 hours, providing high reliability for enterprise networks.
Q
Can I mix different wattage power modules in a D-Link chassis?
A
No; for proper load balancing and redundancy, all installed PSUs must be identical in wattage and model number.
Q
What environmental conditions affect D-Link core switch power supplies?
A
Operate PSUs between 0 °C and 45 °C with 10–90% non-condensing humidity; extreme heat, moisture, or dust may degrade performance or shorten lifespan.
