Power Supplies The 6200 series switches have one internal power supply which requires standard AC. For non-PoE switches, you can also attach a redundant DC power supply, such as the PowerConnect RPS-600. For PoE switches, you can attach a PowerConnect EPS-470. You can verify operation by observing the LEDs. See "System LEDs" for information. Ventilation System Three fans cool the PowerConnect 6224. The PowerConnect 6248 has four fans. You can verify operation by observing the LEDs. See "System LEDs" on page 67 for information on the LEDs. Stacking You can stack up to 12 PowerConnect 6224 and/or 6248 switches, supporting up to 576 front panel ports. Create a stack by connecting adjacent units using the stacking ports on the left side of the switch rear. See Figure 4-13. 1. Connect one of the short stacking cables into either of the stacking ports of the top switch and the switch directly below it. Install a separately purchased stacking module in rear "Bay 1" of each of the switches in the stack. 2. For each switch in the stack, connect one of the short stacking cables from stacking port one on the switch to stacking port two on the next switch. 3. If necessary, use a separately purchased, long (3 meter) stacking cable to connect the switches. Repeat this process until all of the devices are connected. 4. Use the remaining stacking cable to connect the remaining free ports, one each on the top and bottom switches. 62 Hardware Description
