Click

Yes

to restart the management module and end the session.

You can now use an SSH client to start a secure Telnet session with the

management module and secure SOL sessions with the blade servers.

Enabling SOL for blade servers

SOL must be enabled both globally for the BladeCenter unit (see “Configuring the

global SOL settings for the BladeCenter unit” on page 7) and individually for each

blade server where you plan to start an SOL session.

Note:

Make sure that console redirection is enabled for your blade server, with

port 2 (COM 2) specified as the remote console port. Remote console configuration

information for the HS20 Type 8832, HS20 Type 8843, and HS40 Type 8839 blade

servers is in Chapter 4, “Special component requirements,” on page 25. See the

Installation and User's Guide

for your blade server for information about configuring

blade server BIOS settings such as console redirection.

Complete the following steps to enable SOL for a blade server:

1.

Start the BladeCenter management-module Web interface (see “Starting the

BladeCenter management-module Web interface” on page 5).

2.

Complete the following steps to enable SOL on the blade servers:

a.

In the navigation pane, click

Blade Tasks

→

Serial Over LAN

; then, scroll to

the

Serial Over LAN Status

section.

b.

Select each blade server that will have SOL enabled; then, click or select

Enable Serial Over LAN

. (For advanced management modules, you will

also need to click

Perform Action

.) Selecting the check box at the top of the

status table selects all blade servers. The

SOL

column of the table will show

a status of Enabled for each of the blade servers that was selected. The

SOL

Session

column of the table indicates a status of Not Ready for each of the

blade servers that was selected.

c.

To disable SOL for a blade server, select each blade server that will have

SOL disabled; then, click or select

Disable Serial Over LAN

. (For advanced

management modules, you will also need to click

Perform Action

.)

Selecting the check box at the top of the status table selects all blade servers.

The

SOL

column of the table will show a status of Disabled for each of the

blade servers that was selected.

Note:

The blade server SOL status periodically updates itself automatically;

however, you can refresh the window for an immediate display of updated

status.

3.

Complete the following steps to power-on or restart the blade servers on which

SOL was enabled:

a.

In the navigation pane, click

Blade Tasks

→

Power/Restart

.

b.

Select each blade server on which SOL was enabled; then, click either

Power On Blade

or

Restart Blade

, depending on the current status of the

blade servers.

c.

Click

OK

twice to confirm.

4.

Complete the following steps to check the SOL status of the blade servers (see

“Monitoring SOL session status” on page 41 for more information):
