Juniper Networks M160 manual Host Module LEDs, FPC LEDs and Offline Button

Hardware Component Overview

The lines in the display report the following information:

First line—Routing node name.

Second line—Number of active alarms.

Third and fourth lines—Individual alarm messages, with the most severe condition shown first. The prefix on each line indicates whether the alarm is a red (R) or yellow (Y) alarm.

For a list of alarm messages that can appear on the LCD, see “Chassis and Interface Alarm Messages” on page 209.

Host Module LEDs

At the upper right corner of the craft interface (see Figure 11) are two sets of LEDs that indicate host module status: the set labeled HOST0 reports the status of the Routing Engine in slot RE 0 and MCS in slot MCS 0, and the set labeled HOST1 reports the status of the Routing Engine in slot RE 1 and the MCS in slot MCS 1. Each set includes three LEDs—a green one labeled MASTER, another green one labeled ONLINE, and a red one labeled OFFLINE. Table 10 describes the LED states.

Table 10: States for Host Module LEDs

Label	Color	State	Description
MASTER	Green	On steadily	Host module is functioning as master.
ONLINE	Green	On steadily	Host module components (Routing Engine and
			MCS) are installed and functioning normally.
		Blinking	Host module is starting up.
OFFLINE	Red	On steadily	One or both host module components are not
			installed or have failed.

FPC LEDs and Offline Button

The LEDS and offline button for each FPC are located directly above it on the craft interface, as shown in Figure 11. The red LED labeled FAIL and the green LED labeled OK indicate FPC status, as described in Table 11.

The offline button, labeled with the FPC slot number (for example, FPC2), prepares the FPC for removal from the router when pressed.
