Verify the Front Panel LED Indications

The indicator LEDs described in Table 5 provide power, activity, and status information:

Table 5	LED Indicators on Front Panel
LED Label	LED Color or State	Meaning
SYS	Solid green	System is operating normally.
PWR
	Blinking green	System is booting or is in ROM monitor mode.
	Amber	System error.
	Off	Power is off.
AUX/	Green	IP phone power is operating normally (if installed)
PWR		or
		Cisco Redundant Power System (RPS) is operating normally (if installed).
	Amber	IP phone power fault (if installed)
		or
		Cisco Redundant Power System (RPS) fault (if installed).
	Off	IP phone power and Cisco RPS are not installed.
SYS	Blinking green or solid green	Packet transfers are occurring.
ACT
	Off	No packet transfers are occurring.
CF	Green	CompactFlash memory is being accessed; do not eject.
	Off	CompactFlash memory is not being accessed; OK to eject.

Verify the Hardware Configuration

To display and verify the hardware features, enter the following commands:

•show version—Displays the system hardware version; the installed software version; the names and sources of configuration files; the boot images; and the amount of installed DRAM, NVRAM, and flash memory.

•show diag—Lists and displays diagnostic information about the installed controllers, interface processors, and port adapters. Typical examples are network modules, interface cards (VICs, WICs, HWICs), and advanced integration modules (AIMs).

7Interface Numbering

Table 6 summarizes the interface numbering on a Cisco 2801 series router. Table 7 summarizes the interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers.

Note The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600 series routers.

Note On the Cisco 2801 router, the numbering format for slots is interface type 0/slot/port. “0” indicates slots that are built into the chassis of a router. On the Cisco 2801 router, all slots begin with “0,” because all slots are built into the chassis. Note that this is different from the Cisco 2811, Cisco 2821, and Cisco 2851 routers. On these routers, some slots are built into the chassis and have slot numbers that begin with “0.” However, it is possible to have other slots that are part of a network module or an extension voice module. Those slots have slot numbers that begin with “1” or “2,” respectively.
