If the TEMP 

LED

 is amber, the internal temperature of the switch has exceeded the opera-

tional limit.

Perform the following steps:

1. Turn off the switch and wait until it has completely cooled down. 

2. Check the immediate environment and ensure that the switch is not located in an area 

where it can be overheated by other heat-producing devices.

3. Ensure that the switch is located in an area where there is ample room for air flow around 

the chassis.

If the environment is satisfactory, check the internal cooling fans. The switch is shipped with 
redundant fans that start automatically when you power up the unit. Try powering up and 
listen for the fan motors. Also, you should feel a slight air flow near the chassis. If the fans are 
not working, power down and contact Alcatel Technical Support.

There is one status 

LED

 per port on Ethernet switching modules. When lit, it indicates that a 

good cable connection exists to an Ethernet device.

The LAN cable is not connected properly or is faulty.

Check all port connections and inspect the cable. If you find a faulty cable, replace the cable.

You may have saved too many files to the flash file system. If the flash file system is full, it 
will be unable to create the 

 file and it will be unable to complete the boot process.

Unnecessary image or data files exist in the flash file system.

Follow the steps below to free up memory in the flash file system.

1. Reboot the switch and enter the Boot Line prompt. (See Appendix A, “The Boot Line 

Prompt,” for more information.)

2. Use the Boot Line 

 command to delete any necessary files. Make sure you lave enough 

room for the switch to create the 

 file.

3. Use the Boot Line 

 command to continue the boot process.
