C3K-PWR-750WAC is a 750W AC hot-swap power supply for Catalyst 3750-E, Catalyst 3560-E and RPS 2300 hosts. The module gives Catalyst 3750-E 24-port PoE switches 420W of PoE and supports >15.4W on 24 ports. A Cisco Catalyst 3750-E power supply replacement can stay live while RPS 2300 powers the switch. In RPS 2300, one 750W module backs up one attached device; two same-type 750W modules back up two attached devices. Catalyst 3750E or 3560E switches with 1150W power supply need two 750W modules for one active backup. Catalyst 3750-E and Catalyst 3560-E data-only switches use 265W AC or DC modules. C3K-PWR-1150WAC is the 1150W sibling for 48-port full PoE builds and RPS 2300 higher PoE backup.

750W rated output feeds a 100-240V AC, 50-60 Hz circuit with 10-5A input draw. 12V at 25A and -52V at 8.7A output supports system and PoE rails in Catalyst 3750-E, Catalyst 3560-E and RPS 2300 use. 20 ms minimum hold-up time gives the AC circuit a short transfer window. C3K-PWR-750WAC uses an IEC 60320 C13 input receptacle and a 15A power cord. The module measures 42 mm x 152.4 mm x 289.6 mm and weighs 1.8 kg. Operating temperature is -5°C to 45°C. MTBF is 500000 Hours. AC OK and power supply OK LEDs report input and output condition. A single RPS 2300 power supply bay needs BLNK-RPS2300= in the empty bay, and CAB-RPS2300-E= connects RPS 2300 to Catalyst 3750-E or Catalyst 3560-E switches.
New sealed units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year. Certified refurbished C3K-PWR-750WAC units are inspected and bench-tested in a compatible host or on a load tester; output is held at rated voltage under load, and hot insertion and removal are verified in a live host. Order a matching 750W module for a two-bay RPS 2300. Returns are 30 days on every condition; terms apply. UK, EU, US and MEA stock supports RMA with advance replacement, PO accepted and Net-30 for government.

Your failed module label reads C3K-PWR-750WAC or C3K-PWR-750WAC= in a Catalyst 3750-E, Catalyst 3560-E, or RPS 2300 bay. Match the 750W AC rating and IEC 60320 C13 input before the PO. Add CAB-RPS2300-E= for RPS 2300 cable replacement on E-Series switch backups.
Your RPS 2300 has one empty bay or a failed 750W module. A single 750W module backs up one attached device, and two same-type 750W modules back up two attached devices. Keep BLNK-RPS2300= in an unused bay, or order the second 750W module for two-device backup.
Your Catalyst 3750-E or Catalyst 3560-E PoE access pool needs a spare for 24-port and standard 48-port PoE units. Specify the 750W AC module for 420W PoE service. Before the PO, confirm that 48-port full PoE chassis do not carry the 1150W power supply label.
48-port full PoE
C3K-PWR-750WAC gives 420W PoE on Catalyst 3750-E 48PD models and covers up to 24 ports above 15.4W; full 48-port Enhanced PoE takes C3K-PWR-1150WAC.
Single 750W RPS backup
One C3K-PWR-750WAC in RPS 2300 does not back up Catalyst 3750E or 3560E switches with 1150W power supply; use C3K-PWR-1150WAC.
2960-XR internal bays
C3K-PWR-750WAC is an RPS 2300 supply, not a Catalyst 2960-XR internal power supply. A 370W PoE+ 2960-XR spare takes PWR-C2-640WAC=.
-48V DC sites
C3K-PWR-750WAC needs 100-240V AC input. Non-PoE Catalyst 3750-E or Catalyst 3560-E DC replacements use C3K-PWR-265WDC instead.
