Cisco 341-0107-01 enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco 341-0107-01 is an internal AC power supply rated at 210 watts, 100-240V input, built for the Catalyst 3750G and 3560G Series switches. It fits the internal power supply bay on the fixed-configuration chassis used across both families, and since neither the 3750G nor the 3560G takes an external supply, a working unit of this kind is required for the switch to power on at all rather than being an optional redundancy add-on in most single-supply configurations. The 3750G and 3560G were Gigabit-generation Catalyst switches that predate the later 3750-X/3560-X and 3750-V2 ranges, and while long since superseded, a meaningful number remain in service in legacy wiring closets. A failed internal supply is one of the more common reasons an otherwise serviceable 3750G/3560G goes offline, making a spare a sensible stock item. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
