MPCBL0001 Technical Product Specification
Serial Over Lan (SOL)
11.5 Supported Usage Model
Customers are expected to use Serial Over LAN to accomplish the following:
• BIOS console redirection
• As a remote terminal for OS setup and viewing text console output
The ipmitool utility runs on a remote network node and communicates over the LAN interface. The
remote node and the target SBC may be on the same subnet or on different subnets.
The reference script can be run on the remote node.
Note: The machine or “remote node” running ipmitool may also be an MPCBL0001 SBC within the
chassis itself.
11.5.1 Configuring the Blade for SOL
In order to configure a blade for SOL, the machine on which the configurator is installed (typically
the remote node) needs to establish an RMCP connection with the SBC. The configurator sends
commands and configuration settings to the SBC in order to configure and enable SOL operation.
In order to configure a blade for SOL, reference_cfg needs to run either on the same blade as the
IPMC and communicate via the KCS interface, or on a remote node. In the latter case, the script
sends IPMI messages over the LAN to the SBCs shelf manager, which in turn bridges data to the
IPMC’s IPMB-0 interface.
The minimal per-blade configuration that must be set up includes the following:
• an IP/MAC address, subnet mask, default gateway
• ARP configuration
• user ID and password to authenticate access
• channel, user, payload, and SOL privilege levels
The configuration utility is referring to the reference_cfg script described above.
