You can install up to six AC power supplies in a J-EX8200 switch. Power supplies are installed at the bottom of the chassis in slots PSU 0 through PSU 5 (left to right). All power supplies are accessible from the front of the chassis. WARNING: The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground. Each AC power supply weighs approximately 7 lb (3.2 kg) and has an independent 16 A rated AC inlet on its front. Each inlet requires a dedicated AC power feed. Each AC power supply has an Enable switch, a fan, and three LEDs on the faceplate that indicate the status of the power supply. See Figure 21 on page 34. Figure 21: AC Power Supply 34
