Hardware Features
Power
Table 4 summarizes the power options for Cisco 2800 series routers. Cisco 2801 routers are equipped
for operation using AC power only. Cisco 2811, Cisco 2821, and Cisco 2851 routers can be equipped for
operation using either AC or DC input power by installation of the appropriate chassis power supply. IP
phone power is supported if the appropriate AC-input chassis power supply is installed.
LED Indicators
Table 5 and Table 6 summarize the LED indicators that are located in the router bezel or chassis, but not
in removable modules or interface cards.
