Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

Figure 4-1and Figure 4-2show the AC-input power supplies. Figure 4-3and Figure 4-4show a the DC-input power supplies. Locate your power supply and notice the location of the captive installation screws.

Note The power supplies are hot-swappable, so in redundant mode you will not need to power down the switch to replace or upgrade most power supplies. In combined mode some slots may lose power during an upgrade or power supply replacement.
