The WS-C4503 is a Cisco Catalyst 4503 3-slot modular switch chassis with a fan and no power supply. Slot 1 is reserved for the supervisor engine, and slots 2 and 3 take switching modules. Standard equipment is one hot-swappable fan assembly with two fans and two power supply bays, with an optional redundant supply.
Power supply options are a 1000 W, 1300 W, 1400 W, 2800 W or 4200 W AC-input supply, or a 1400 W DC-input single-input or triple-input supply. Airflow runs right to left through the switch and front to back through the power supply, and filler plates must cover unused module slots.
The chassis measures 12.25 x 17.31 x 12.50 in. (31.12 x 43.97 x 31.70 cm). Maximum weight is 75 lb (34 kg), including 29 lb (13.1 kg) for chassis and backplane and 2.25 lb (1.0 kg) for the fan tray. Switching modules it takes include the WS-X4124-RJ45 24-port 10/100 module and the 48-port WS-X4148-RJ. Other Catalyst parts are in Cisco switches.
