ENV LED on the MSM turns amber:
Check each of the power supplies and all of the fans. Additionally, the status of these is indicated in the

displays.
Switch does not power up:
All products manufactured by Extreme Networks use digital power supplies with surge protection. In
the event of a power surge, the protection circuits shut down the power supply. To reset, unplug the
switch for 1 minute, plug it back in, and attempt to power up the switch.
If this does not work, try using a different power source (different power strip/outlet) and power cord.
Using the Command Line Interface
The initial welcome prompt does not display:
Check that your terminal or terminal emulator is correctly configured.
For console port access, you may need to press [Return] several times before the welcome prompt
appears.
Check the settings on your terminal or terminal emulator. The settings are 9600 baud, 8 data bits, 1 stop
bit, no parity, XON/OFF flow control enabled.
The SNMP Network Manager cannot access the device:
Check that the device IP address, subnet mask, and default router are correctly configured, and that the
device has been reset.
Check that the device IP address is correctly recorded by the SNMP Network Manager (refer to the user
documentation for the Network Manager).
Check that the community strings configured for the system and Network Manager are the same.
Check that the SNMPv3 USM, Auth, and VACM configured for the system and Network Manager are
the same.
