C4KX-PWR-750AC-R is the 750 W AC-input power supply for the Cisco Catalyst 4500-X Series switches. The -R version has front-to-back airflow, and its release lever is colour-coded burgundy to mark the warm side. C4KX-PWR-750AC-F is the back-to-front airflow version.
The input is autoranging with power factor correction: 100 to 240 VAC single-phase (115/230 VAC nominal) at 47 to 63 Hz. Maximum input current is 11 A at 100 VAC and 6 A at 200 VAC.
The supply has no power switch, so it powers up as soon as the AC outlet is live. Two LEDs sit at the lower left of the front panel: OK is green and FAIL is amber. A solid green OK LED with FAIL off means the supply is on and working normally.
The module measures 1.57 x 2.15 x 14.28 in (3.99 x 5.46 x 36.27 cm) and weighs 2 lb (0.91 kg). A bay with no supply takes the C4KX-PWR-BLANK blank cover.
