How to Enable Serial Over LAN

2. Navigate to Serial Over LAN (BladeTasks → Serial Over LAN)

3. Enable SOL for your specific server:

   • Locate the section Serial Over LAN Status. It should show a table of your bays and blade servers.
   • Check the server(s) for which you would like to enable SOL
   • Click Enable Serial Over LAN link

4. Enable Serial Over LAN service by using the drop down box under Serial Over LAN Configuration

5. Click Save

6. Ensure that SSH is enabled.

SSH can be assigned to non-standard ports in the BladeCenter. This can be checked under MM Control → Port Assignments.

How to Connect to the Console

1. SSH into the BladeCenter

2. List the available blades:

system> list -l 2
system
	blade[1]  S_BEELA030
	blade[3]  S_BEELA032
	blade[5]  BELEAIX01_16953
	blade[6]  BELEAIX02_16954
	blade[7]  BELEAIX03_17708
	blade[8]  BELEAIX04_17707
	blade[10]  S_BESRV001
	blade[11]  S_BESRV002
	blower[1]
	blower[2]
	power[1]
	power[2]
	power[3]
	power[4]
	mm[1]     standby
	mm[2]     primary
	switch[1]
	switch[2]
	switch[7]
	switch[8]
	switch[9]
	switch[10]
	mt[1]

3. Set the environment variable to your blade bay number, then type console. If you don’t know your bay number, log into the BladeCenter GUI, http://10.1.1.1.

An example for connecting to the blade on bay 1:

system> env -T system:blade[1]
system:blade[1]> console
Console login:

4. To escape back into the BladeCenter CLI, use the escape sequence listed under SOL in the Blade Center GUI. The default sequence is ^[(. That is Ctrl+AltGr+[ and then (.

How to set the Telnet timeout to unlimited

1. Set the target to the active MM:

system:mm[1]> env -T system:mm[2]    * To enable SSH (the more secure option)
OK

2. Set timeout value to 0:

system:mm[2]> telnetcfg -t 0
OK
