b.
The enabled LED comes on after the I/O power OK LED and indicates that the network
processing engine and the I/O controller are enabled for operation by the system; however, it
does not mean that the Fast Ethernet port on the I/O controller is functional or enabled. This
LED goes on during a successful boot and remains on during normal operation of the
Cisco uBR7200 series router.
If this LED remains off when you start the router, it is probably a problem with the network
processing engine or the I/O controller (they are damaged or not connected to the
Cisco uBR7200 series router midplane), or the Fast Ethernet port is in shutdown mode. Refer
to the
“Troubleshooting the I/O Controller” section on page 6-6
and the
“Troubleshooting the
Network Processing Engine” section on page 6-7
.
c.
The FE enabled LED comes on after the enabled LED and indicates that the Fast Ethernet port
on the I/O controller is initialized and enabled for operation by the system. This LED comes on
during a successful boot and remains on during normal operation of the Cisco uBR7200 series
router.
If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet
port on the I/O controller. Refer to the
“Troubleshooting the I/O Controller” section on
page 6-6
.
d.
The FE link LED comes on only when the Fast Ethernet port on the I/O controller is receiving
a carrier signal from the network. This LED remains off during normal operation of the router
unless there is an incoming carrier signal, and does not indicate startup problems.
e.
The slot 1 and slot 2 LEDs come on after the enabled LED and indicate which Personal
Computer Memory Card International Association (PCMCIA) slot is in use. During a successful
boot, these LEDs come on and remain on if a flash memory card is present in the slot. These
LEDs also blink when either slot is being accessed by the system. These LEDs do not indicate
startup problems.
4.
The enabled LED on each port adapter comes on when the network processing engine completes its
initialization of the port adapter for operation. The enabled LED indicates that the port adapter is
receiving power and has been recognized by the network processing engine; it does not indicate the
state of the individual interfaces on the port adapters. If an enabled LED fails to come on, refer to
the
“Troubleshooting Port Adapters” section on page 6-8
.
5.
The enabled LED on the cable clock card (Cisco uBR7246VXR only) comes on when the network
processing engine completes its initialization of the cable clock card for operation. The enable LED
indicates that the cable clock card is receiving power and has been recognized by the network
processing engine; it does not indicate the state of the primary or secondary interfaces on the cable
clock card. If the enable LED fails to go on, refer to the
“Troubleshooting the Cisco Cable Clock
Card (Cisco uBR7246VXR Only)” section on page 6-8
.
6.
The enabled LED on each cable interface line card comes on when the network processing engine
completes its initialization of the card for operation. The enabled LED indicates that the card is
receiving power and has been recognized by the network processing engine; it does not indicate the
state of the individual interfaces on the card. If an enabled LED fails to come on, refer to the
“Troubleshooting Cable Interface Line Cards” section on page 6-9
.
7.
When all LEDs come on to indicate that the system has booted successfully, the initial system
banner should appear on the console screen. If it is not displayed, refer to the
“Console and
Auxiliary Port Connection Equipment” section on page 3-16
to verify that the terminal is set
correctly and that it is properly connected to the I/O controller’s console port.
