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.
