LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.

The LCD panel operates in boot mode during switch reboot. The boot mode displays the key milestones in the switch boot process. The boot mode does not have any menu options. After the boot process is complete, the LCD panel automatically reverts to the Idle menu.

The first line of text on the LCD panel displays the slot number, the role of the switch, and hostname. For a standalone EX4500 switch, the slot number is always 00, and the role is always RE.

In an EX4500 switch that is a member of a Virtual Chassis, the first line of the LCD panel displays:

• The slot number (the member ID for the Virtual Chassis member)

• Role of the switch in a Virtual Chassis (RE for master, BK for backup, and LC for linecard member)

• Hostname

In the idle mode, the second line of text on the LCD panel displays the mode of the network ports’ Status LED and the number of chassis alarms. The number of alarms is updated every second.

In the status mode, the second line displays:

• Virtual Chassis port (VCP) status (supported only on EX4500 switches in a Virtual Chassis configuration running Junos OS Release 11.1 or later. This option is not supported on standalone EX4500 switches.)

• Status of the power supplies

• Status of the fans in the fan tray and the chassis temperature

• Version of Junos OS for EX Series switches loaded on the switch

In the maintenance mode, the second line displays one of the following options that you can use to configure and troubleshoot the switch:

• System halt

• System reboot

• Load rescue

• Request VC port (supported only on EX4500 switches in a Virtual Chassis configuration running Junos OS Release 11.1 or later. This option is not supported on standalone EX4500 switches.)

• Factory default

• EZSetup

LCD Panel Menus

The LCD panel has three menus: Idle, Status, and Maintenance. You can toggle between the LCD panel menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.

Table 1 describes the LCD panel menu options.

Virtual Chassis Module in EX4500 Switches

The Virtual Chassis module is installed horizontally on the rear panel of an EX4500 switch chassis. The Virtual Chassis module has two dedicated Virtual Chassis ports (VCPs) that can be used to interconnect the EX4500 switch with an EX4200 switch or an EX4500 switch in a Virtual Chassis configuration. The module is an offline field-replaceable unit (FRU).

The Virtual Chassis module comes preinstalled in the switch chassis in the EX4500-40F-VC1-FB, EX4500-40F-VC1-BF, and EX4500-40F-VC1-DC switch models. You must order it separately for all other switch models. See EX4500 Switch Models.

Figure 6 shows the Virtual Chassis module.

Figure 6: Virtual Chassis Module

The Virtual Chassis module has two LEDs (labeled ST and VC MODE ) on the left side of its faceplate that indicate the status and the operating mode of the Virtual Chassis module. See Figure 7.

Figure 7: Virtual Chassis Module LEDs

Table 2 describes the LEDs on the Virtual Chassis module in an EX4500 switch.

The Virtual Chassis module has two captive screws on the faceplate that secure the module to the switch chassis. To remove or replace the Virtual Chassis module, follow the instructions in Removing a Virtual Chassis Module from an EX4500 Switch.

Chassis Status LEDs in EX4500 Switches

The front panel of an EX4500 switch has three chassis status LEDs (labeled ALM, SYS, and MST) on the far right side of the panel, next to the Menu and Enter buttons (see Figure 8).

Figure 8: Chassis Status LEDs in an EX4500 Switch

Table 3 describes the chassis status LEDs in an EX4500 switch, their colors and states, and the status they indicate. You can view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis led.

A major alarm (red) indicates a critical error condition that requires immediate action.

A minor alarm (amber) indicates a noncritical condition that requires monitoring or maintenance. A minor alarm that is left unchecked might cause interruption in service or performance degradation.

All three LEDs can be lit simultaneously.

Management Port LEDs in EX4500 Switches

The management port on the front panel of an EX4500 switch has two LEDs that indicate link/activity and port status (see Figure 9).

Table 4 describes the Link/Activity LED.

Table 5 describes the Status LED.

Uplink Modules in EX4500 Switches

EX4500 switches support SFP+ uplink modules. The SFP+ uplink module is a hot-insertable and hot-removable field replaceable unit (FRU).

You can install up to two SFP+ uplink modules in an EX4500 switch. Both uplink modules install horizontally on the front of the chassis. The uplink module slot on the left is PIC 1. The uplink module slot on the right is PIC 2. See Figure 10.

Figure 10: Uplink Module Slots in an EX4500 Switch

Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit small form-factor pluggable (SFP+) transceivers or four 1-gigabit small form-factor pluggable (SFP) transceivers.

The operating mode for an SFP+ uplink module is shown in the output of the show chassis pic fpc-slot slot number pic-slot 1 command.

You can use the uplink module ports to connect an access switch to a distribution switch.

Figure 11 shows the SFP+ uplink module.

Figure 11: SFP+ Uplink Module

The SFP+ uplink module has an LED on the faceplate (labeled ST) that indicates the status of the uplink module. See Figure 11.

Table 6 describes the LED on the uplink module in an EX4500 switch.

Each uplink module port has a pair of LEDs that indicate the link/activity and status of the port. See Network Port and Uplink Module Port LEDs in EX4500 Switches for details about the uplink module port LEDs.

SFP+ uplink modules are shipped with dust covers preinstalled in the ports.

SFP+ uplink modules require Junos OS for EX Series switches, Release 9.4 or later.

Intraconnect Module in EX4500 Switches

The intraconnect module is installed horizontally on the rear of an EX4500 switch chassis. The intraconnect module helps the switch achieve line rate on all its ports. The module is an offline field-replaceable unit (FRU).

The intraconnect module comes preinstalled in the switch chassis in the EX4500-40F-FB, EX4500-40F-BF, EX4500-40F-FB-C, EX4500-40F-BF-C, and EX4500-40F-DC-C switch models. You must order it separately for all other switch models. See EX4500 Switch Models.
