7705 SAR-M Connectors and LEDs (Variants with Module Slot, Actively Cooled)
148 7705 SAR-M Chassis Installation Guide
6 Alarm LEDs Crit. Red: Indicates that a critical condition exists, such as the failure of two
or more fans or a power feed, or a critical external alarm input detected.
If ADP is running, this indicates that ADP is halted.
Blinking: Indicates that ADP is running, when blinking in sequence with
the Major and Minor LEDs
Unlit: Indicates that there are no critical alarm conditions
Maj. Red: Indicates that a serious condition exists, such as an
over-temperature condition or a major external alarm input detected. If
ADP is halted, this LED, in combination with the Minor LED, indicates
the ADP stage. See Automatic Discovery Protocol for more information.
Blinking: Indicates that ADP is running, when blinking in sequence with
the Critical and Minor LEDs
Unlit: Indicates that there are no major alarm conditions
Min. Amber: Indicates that a minor condition exists, such as the failure of a
single fan or a minor external alarm input detected. If ADP is halted, this
LED, in combination with the Major LED, indicates the ADP stage. See
Automatic Discovery Protocol for more information.
Blinking: Indicates that ADP is running, when blinking in sequence with
the Critical and Major LEDs
Unlit: Indicates that there are no minor alarm conditions
7 Stat (Status)
LED
— The system status LED indicates the combined status of the router’s four
main functional blocks (the control and switching functional block, the
T1/E1 ports functional block (for the variant with T1/E1 ports), the
Ethernet ports functional block, and the module block). Blocks that are
administratively shut down are not included in the combined status
indicated by this LED.
Green (solid): Indicates that the system is operationally up, which means
that all functional blocks configured to be administratively up are
operationally up
Green (blinking): Indicates that one or more functional blocks is
initializing
Green and Amber (blinking): Indicates that ADP is running on the
system
Unlit: Indicates that the system is operationally down
