3.1 Introduction
This chapter describes the MX250 hardware along with the telecommunications and data
communications interfaces.
3.2 Front Side of MX250
The front panel side of the MX250, as is shown in figure 3-1, has no wiring connectors. Chapter 7,
starting on page 37, describes the LED indicators.
The numbers in figure 3-1 correspond to the following components:
1. Power LED – During normal operation, the Power LED indicates the status of ac power and
battery applied to the MX250.
2. Load LED – During normal operation, the Load LED indicates system service accesses and
storage availability for applications, reports, and voice mail.
3. Status LED – During normal operation, the Status LED indicates the status of firmware
update, fan failure, temperature, console mode, and exceptions.
During system start up and shut down, the MX250 uses all LEDs to indicate procedure
completion. See Chapter 7, starting on page 37, for a description of MX250 LEDs.
