5.5.2 System Status LEDs
The following system status LEDs are located on the front face of the SDM-9606 blade:
•
OOS
(Out Of Service; green/amber) goes on (green) when the blade is powered
on; turns amber when the card has failed in a chassis that has been powered on
•
ST
(Status, red/amber/green) indicates the current program status on the blade, as
shown in Table 5-5
•
ALM
(Alarm; red/amber/green) indicates several alarm states, including a system
alarm when a software reset occurs. See Table 5-6
•
H/S
(Hot Swap: blue), located on the right side of the blade, goes on and blinks
when the card handles are opened, indicating that the blade is NOT READY for
removal. The blade can be removed when this LED turns off. Refer to
“Remov-
ing a Blade” on page 4-12 .
The E1/T1 port status LEDS are described on “E1/T1 Port Status LEDs” on page 5-16 .
