Table 1-2	ISA LEDs
LED Label		Color	State	Function
ENABLE		Green	On	Indicates the ISA is powered up and enabled for
				operation.
BOOT		Amber	Pulses1	Indicates the ISA is operating.
			On	Indicates the ISA is booting or a packet is being
				encrypted or decrypted.
ERROR		Amber	On	Indicates an encryption error has occurred.
				This LED is normally off.

1.After successfully booting, the boot LED pulses in a “heartbeat” pattern to indicate that the ISA is operating. As crypto traffic increases, the nominal level of this LED increases in proportion to the traffic level.

The following conditions must all be met before the enabled LED goes on:

•The ISA is correctly connected to the backplane and receiving power.

•The system bus recognizes the ISA.

If either of these conditions is not met, or if the router initialization fails, the enabled LED does not go on.

The ISM has three LEDs, as shown in Figure 1-5. Table 1-3lists the colors and functions of the LEDs.
