Controller Cards
A controller card has the following LEDs; see Figure 5-2:
• Four equipment LEDs—Indicate current card status
• One synchronization and two external timing LEDs—Indicate the status of any connected external
timing source
• Two facility LEDs—Indicate status of the Ethernet port
Table 5-3 lists the equipment LEDs, which indicate current status of the card.

Description
FAIL
On
Red
A failure exists on the controller card.
1
1. A failure can be total, partial, or forced. Failure on any part of the card, including failure of any of its ports, results in the FAIL LED being
lit.
Blinking
Red
Standby controller is being synchronized with the active controller.
2
2. The synchronization process is not affected by traffic card installation and removal; the active controller, and hence the system,
continues to be responsive to traffic forwarding and continues to detect and notify the administrator of any faults that occur while the
standby controller is being synchronized.
Off
None
No failure exists on the controller card.
ACTIVE
On
Green
This controller card is the active controller.
Off
None
This controller card is either on standby (the STDBY LED is lit) or has failed (the
FAIL LED is lit).
STDBY
On
Yellow
This controller card is the standby controller for the system.
Off
None
This controller card is either the active controller for the system (the ACTIVE LED
is lit) or has failed (the FAIL LED is lit).
CF

3. XCRP4 Controller card only.
On
Green
• The slot is empty, and it is safe to insert a CF card.
• The file system on the installed CF card is not mounted, and it is safe to
remove the CF card.
Blinking
Green
A CF card is installed in the slot, and the SmartEdge OS is mounting or
unmounting the file system.
Off
None
A CF card is installed, the file system is mounted, and the SmartEdge OS might
be transferring data to or from the CF card.
CF
ACTIVE
4
4. XCRP and XCRP3 Controller cards only.
Blinking
Green
The external storage device in the slot in the active controller card is being read
or written.
Off
None
No read or write operation on the external storage device is in progress.
Note
When you first power on the system, the active controller card is in slot 7. Thereafter, the slot
changes whenever a switchover occurs. Check the status of the ACTIVE LED or use the
show
chassis
command (in any mode) to determine the slot number.
