Shelf Manager CLI
To restart the shelf manager snmpd process
1. Enter the following command to list all processes running on the shelf manager:
ps
2. Search the output for a line that contains snmpd -c /etc/snmpd.conf. For example:
930 root 2264 S snmpd -c /etc/snmpd.conf
3. Enter the following command to stop this process:
kill -9 930
In this example, the ID of the process to be stopped is 930. On your shelf manager the process ID will most likely
be different.
4. Enter the following command to restart the snmpd process:
# daemon -f snmpd -c /etc/snmpd.conf
5. To confirm that the process has restarted enter the ps command again and confirm that the snmpd process is in
the list.
6. Use an SNMP manager or any tool that can send SNMP queries (for example iReasoning or Wireshark) to verify
that the shelf manager can respond to SNMP polling requests using the configured community strings.

Using the shelf manager system event log (SEL)

The chassis system event log (SEL) records all system events and this section describes how to read and interpret the
SEL.

Before you begin

Before going further in this section, you should log into your active shelf manager and enter the following commands.
This will be a good reference for what you physically have in your system and will help with understanding other areas of
this section.

Chassis design background

All the devices in an ATCA chassis are controlled and monitored through an Intelligent Platform Management
Controllers (IPMC). Each shelf manager and all ATCA boards have their own physical IPMC chip and are assigned an
IPMC address. Their unique address is assigned based on what chassis slot they are physically inserted into.
Additionally, there is a reserved logical chassis IPMC address of 20 hex which is created and controlled by the active
shelf manager.
Shelf Manager slot 1 = IPMC address 10
l
Shelf Manager slot 2 = IPMC address 12
l
ATCA slot 1 = IPMC address 82
l
ATCA slot 14 = IPMC address 9C
l
Logical IPMC from Active Shelf Manager = IPMC address 20
l
The IPMC connects to and monitors the readings on various sensors located on devices in the system. These
