The IBM eServer BladeCenter JS20 - IBM Redbooks

5.5.1 Configuring Serial over LAN
Before you attempt to configure the SoL remote text console function, verify that
you have all the prerequisites in place:
► A supported LAN switch module installed in I/O module bay 1
This switch module is used to provide a VLAN that connects the Management
Module to the first Ethernet interface on each blade server.
► The minimum firmware levels described in 5.4, “Firmware” on page 79
This is important if you install a BladeCenter JS20 in an existing BladeCenter
chassis that may have back-level firmware in the Management Module or LAN
switch modules.
► A reliable Telnet or SSH client
► A network connecting the Telnet or SSH client to the BladeCenter
Management Module external 10/100BaseT Ethernet interface
► An identified range of IP addresses that will be used by the Management
Module to communicate with the BSMP on each blade server via the private
VLAN
This was discussed in Chapter 4, “Planning considerations” on page 53.
The easiest way to configure the SoL remote text console function is through the
Management Module Web interface as explained in the following steps.
To configure the SoL remote text console function, use the following procedure:
1. From the Management Module Web interface, select Blade Tasks → Serial
Over LAN.
2. In the right pane, scroll down until you see the Serial Over LAN Configuration
section (see Figure 5-12). Complete the following tasks:
a. From the Serial over LAN list, select the Enabled option.
b. Leave the value for SoL VLAN ID at the default (4095) if you have either a
4-port Gigabit Ethernet Switch Module or a Nortel Networks Layer 2-7
Gigabit Ethernet Switch Module installed in I/O module bay 1.
If you have a Cisco Systems Intelligent Gigabit Ethernet Switch Module
installed in I/O module bay 1, set the VLAN ID to the same value you used
when you manually defined the VLAN that supports SoL.
c. Enter the start of the IP address range that will be used by the
Management Module to communicate with the BSMP on each blade
server.
d. Leave the values for Accumulate timeout, Send threshold, Retry count,
and Retry interval at their defaults (5, 250, 3, and 250).
