102
The IS LED of the ATCA-7150 blinks (red). The alarm severity varies with the blinking frequency.
The higher the blinking frequency, the more serious the alarm.
The IS LED can be green or red. The working state of the ATCA-7150 decides the color of the
LED.
The blinking frequency of the IS LED indicates the alarm level:
z For a minor alarm, the IS LED blinks at a frequency of 0.5 Hz.
z For a major alarm, the IS LED blinks at a frequency of 1 Hz.
z For a critical alarm, the IS LED blinks at a frequency of 4 Hz.
Solution
By using the SMM command, query the status and logs of the blade where the alarm occurs.
If an alarm occurs due to over high temperature, confirm that:
1. The temperature in the equipment room meets the operating requirements for the
product.
2. The air intake vents and exhaust vents of the shelf are not blocked.
3. Blank filler blades are installed in the vacant slots of the shelf.
4. The fans are adjusted to the required speed.
