Serial Interface Operation
This section describes remotely configuring and monitoring an Eaton Advanced Enclosure Power Distribution
Unit (ePDU) through the serial connection between the ePDU internal Network Management Card and a laptop
or workstation.
Access to a Serial interface command line interface (CLI) is provided through a terminal emulation program,
such as HyperTerminal or PuTTy, or through Telnet.
Once connected, you can perform basic configuration and monitoring tasks for the ePDU to which you are
connected, including the following:
l
Retrieve selected meters and measurements, including current, present power, temperature, and input
voltage
l
Set or retrieve ePDU critical alarm high threshold values
l
Set or retrieve high temperature warning or alarm threshold values, and low humidity warning or alarm
threshold values
l
Set or retrieve settings for dry contact sensors connected to the ePDU
l
Retrieve selected ePDU equipment, software version, and ratings information
l
Reset the ePDU settings to factory defaults or reboot the ePDU
SNMP Agent
The Network Management Card embeds a Simple Network Management Protocol (SNMP) agent. The SNMP
agent supports the following SNMP versions:
l
SNMPv1
l
SNMPv3
l
SNMPv1 and v3
The SNMP agent is disabled by default and uses default port 161.
The SNMP agent implements the SNMP MIB-II and the Eaton MIB. The Eaton MIB files can be downloaded
from the ePDU Web interface.
NOTE
A terminal emulation program can communicate with another computer or network
as if it were a specific type of terminal directly connected to that computer or
network.
NOTE
The ePDU defaults to using Dynamic Host Configuration Protocol (DHCP) when
delivered. If you are unable to connect to the ePDU through the network connection
with this default address, change the IP address using the serial interface before
using any of the network interfaces.
NOTE
The Management Information Base (MIB) objects are not described in this
document. Use a MIB browser tool on a PC for descriptions of the MIB objects and
traps with comments.
