SNMP Support for the External PDU Power Management Controller Board

The PowerEdge C8000 server enclosure is primarily connected to an external PDU. The external PDU includes a power management controller (PMC) board that allows you to monitor the PDU power supply modules over the network. When an error occurs in the PDU, the PMC via SNMPv2 send notifications to the remote client.

There is a common OID (object identifiers) defined in the MIB (Management Information Base) file. Use the SNMP utility to get the SNMPv2-MIB file and load the MIB files that are required for managing and monitoring the PDU.

PMC Network Connection

By default, the PMC is configured to automatically obtain an IP address via DHCP server. A special button-press-sequence MUST be defined that does not conflict with legacy fan controller,

Long press in 4 seconds, service mode.

3 short presses in less than 5 seconds provide switch between default static IP and reset to default

After PMC resets, all network and configuration settings restore back to their default values. PMC is configured with the following default network settings.

IP address: 192.168.0.120

Subnet mask: 255.255.255.0

The power/status indicator on the front of the PMC board displays the following behaviors

Blinking amber (500 ms off/5 s on) — Restarts the PMC firmware and reset to factory default is completed.

Blinking amber (250 ms off/5 s on) — Restores the default network settings to their default values.
