1.2.2 Serial over LAN
Serial over LAN (SOL) is an IPMI v.2.0 defined capability that allows to establish a virtual serial
console connection with the payload over LAN. The serial data of the payload is transferred to
the IPMC. The IPMC generates RMCP+ packets, which are routed to the ethernet controller of
the base interfaces. Be aware that SOL/LAN configuration is only possible if the Ethernet
controller and its payload is fully powered, otherwise the completion code 0xD5 is returned. For
more information on how to use and configure SOL see Chapter 4, SOL Module Configuration,
on page 53.
1.2.3 Sensors
Apart from several voltage and temperature specific sensors (for details refer to Sensor Data
Records on page 29), the IPMC provides the following additional sensors:
1.2.4 MAC Address Record
The ATCA-7350 implements an MAC address FRU OEM record. You can retrieve all MAC
addresses of the blade from the FRU information. For more details refer to MAC Address
Record on page 27.
1.2.5 Asynchronous Event Notification
To enable payload applications to be informed about graceful shutdown/reboot requests, the
FRU Activate (Deactivate) and FRU Control (Graceful Reboot) command message is routed as
a LUN2 message to the payload interface.
If the payload application has registered to these commands via the OpenIPMI library, it gets
informed and can take all necessary actions before the payload is gracefully rebooted or shut-
down.
1.2.6 Graceful Shutdown Timeout
The IPMI command Set System Boot Options together with the parameter #98 can be used to
persistently specify the timeout for Graceful Shutdown. For more information refer to Chassis
Device Commands on page 18.

Sensor Description
Firmware Progress, and Boot
Error Sensor
The IPMC firmware provides Firmware Progress (Table 3-24 on page
43), and Boot Error (Table 3-16 on page 37) sensors to enable
payload firmware and payload OS to report boot progress and OS
Boot via IPMI event messages.
