Temperature Sensor
Every EP module contains a temperature sensor. Depending on the temperature reported by the sensor, the
software can send a warning if the temperature exceeds the normal threshold and can even shut the device down
if the temperature exceeds the safe threshold. The software reads the temperature sensor according to the
system poll time, which is 60 seconds by default.
You can display the temperature of the device. You also can change the warning and shutdown temperatures and
the chassis poll time. See "Using the Temperature Sensor" on page 6-48.
J4885A EP Management Module
The J4885A management module is based on M4 technology for enhanced performance. Figure B.1 shows the
front panel of an EP Gigabit management module.

Gigabit Ethernet Network Interfaces
The EP Gigabit Ethernet management module provides eight miniature Gigabit Interface Converter (mini-GBIC)
slots. You can insert a 1000BaseSX, 1000BaseLX, or 1000BaseLH fiber connector into each slot, in any
combination.
The LEDs listed in Table B.3 provide status information for the ports.
