Compatible replacement for specific switch models

This 300W ATX power supply is designed as a direct replacement for the S6502, S6502XG, 7502 and LS8M5220PWR PSR300-A units. It arrives new and has been tested to confirm working operation. Network administrators and IT technicians maintaining compatible switching hardware will find it a suitable spare.

Upgrade from a failed or ageing original unit

The supply replaces a defective PSR300-A to restore power to the supported switch chassis. The jump is worth it when the existing unit has failed, shows instability or has reached end of life. It is not for builders needing a standard PC ATX pinout, higher wattage output or modular cabling for a custom computer build.

Questions about this item

What ATX form-factor dimensions does the PSR300-A need to fit inside the switch chassis?

The PSR300-A follows the standard ATX power supply form factor, so it mounts in any chassis bay designed for a 300 W ATX unit.

Which screw-hole pattern and connector orientation must align when installing the PSR300-A in an S6502 or 7502 switch?

Align the four standard ATX mounting holes with the chassis rails, then seat the LS8M5220PWR edge connector firmly; the most common error is leaving the connector partially inserted.
