Serial and Ethernet Connection Status
The serial and Ethernet connectors provide status indicators. The color display and the LED state convey the
operation condition of the ePDU. Table 9 provides a description of the LED displays for the serial and Ethernet
connectors.
Remote Interfaces
You can communicate with the ePDU using the remote interfaces listed in Table 10.
NOTE
At startup, check the LED status display colors on the communication and
monitoring ports to ensure that they are operating correctly.

Port
Description
Serial connector
Connects to the serial (COM) connector on a computer with a DB9-to-RJ-45 cable, allowing the computer to act as a
configuration console.
l
Green LED OFF when the ePDU is starting.
l
Green LED ON when the Network Management Card starts communicating with the ePDU.
l
Green LED Flashes when the Network Management Card is operational.
l
Orange LED OFF when the console menu is activated.
l
Orange LED ON for normal operation, but the console menu is not activated.
l
Orange LED Flashes when the Network Management Card card is communicating with the EMP sensor (optional equipment).
NOTE
The LED also flashes when no device is connected to the ePDU.
Ethernet connector
Connects to a LAN, allowing access through a 10/100 autosensing network connection. Used for remote configuration and
equipment monitoring. Can be used as anEnvironmental Monitoring Probe (EMP) sensor connector instead.
l
Green LED OFF when the port is operating at 10 Mbits/s.
l
Green LED ON when the port is operating at 100 Mbits/s.
l
Orange LED OFF when the ePDU is not connected to the network.
l
Orange LED ON when the ePDU is connected to a 10 Mb network, but with no activity.
l
Orange LED Flashes while data is transmitted and received.
