LCD Panel in EX4300 Switches

The LCD panel on the front panel of the EX4300 switch shows two lines of text, each with a maximum of 16 characters. The LCD panel displays a variety of information about the switch and also provides a menu to perform basic operations such as initial setup and reboot.

There are two navigation buttons—Menu and Enter—to the right of the LCD panel.

See Figure 1.

LCD Panel Modes

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

The first line of text on the LCD panel displays the slot number, the role of the switch, and hostname in all the modes.

For a standalone EX4300 switch, by default the slot number is 00, and the role is RE.

In an EX4300 switch that is a member of a Virtual Chassis, the first line of the LCD panel always displays:

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

  • Role of the switch in the Virtual Chassis (RE for primary, BK for backup, and LC for line card member)

  • Hostname

The LCD panel operates in boot mode during switch reboot. In the boot mode, the second line of the LCD panel 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 (IDLE) menu.

In 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 status mode, the second line displays:

  • Status of the Virtual Chassis port (VCP)

  • Status of the power supplies

  • Status of the fan modules and the chassis temperature

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

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

  • System halt

  • System reboot

  • Load rescue

  • Request VC port

  • 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.

Note

When you install an uplink module in the switch or replace an uplink module with another uplink module, the switch detects the ports on the uplink module. The switch creates the required interfaces when transceivers are installed in these ports.

The SFP+ uplink module ports in EX4300 switches can operate either in 10-gigabit or in 1-gigabit mode depending on the transceiver you install in them. The operating mode for an SFP+ uplink module is shown in the output of the show chassis pic fpc-slot slot number pic-slot slot number command.

Each port on the uplink modules has a pair of LEDs that indicate the link activity and status of the port. See Network Port, Built-In QSFP+ Port, Uplink Port, and Uplink Module Port LEDs on EX4300 Switches for details about the status and link activity LEDs.

SFP+ uplink modules are shipped with dust covers installed in the ports. QSFP+ uplink module is shipped with a dust cover installed in one of the ports.

Chassis Status LEDs on EX4300 Switches

EX4300 switches except EX4300-48MP and EX4300-48MP-S switches have three chassis status LEDs (labeled ALM, SYS, and MST) on the right of the LCD panel, next to the Menu and Enter buttons (see Figure 11). EX4300-48MP and EX4300-48MP-S switches have three chassis status LEDs (labeled ALM, SYS, and MST) on the right of the front panel (see Figure 12).

LED Label

Color

State and Description

ALM (Alarm)

Unlit

There is no alarm or the switch is halted.

Red

There is a major alarm. A major alarm indicates a critical error condition that requires immediate attention.

Note: When you connect power to the switch, the Alarm (ALM) LED glows red. This behavior is normal. Plugging an active Ethernet cable into the management (MGMT) port on the switch completes the network link and turns off the ALM LED. (See Connect a Device to a Network for Out-of-Band Management.)

Connecting the switch to a dedicated management console instead of a network does not affect the ALM LED. The LED remains red until the switch is connected to a network.

Yellow (on EX4300 switches except EX4300-48MP and EX4300-48MP-S switches) or amber (on EX4300-48MP and EX4300-48MP-S switches)

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

Note: The Alarm (ALM) LED glows yellow on EX4300 switches except EX4300-48MP and EX4300-48MP-S switches or amber on EX4300-48MP and EX4300-48MP-S switches if you commit a configuration to make it active on the switch and do not also create a rescue configuration to back it up. To save the most recently committed configuration as the rescue configuration, enter the operational mode command request system configuration rescue save.

SYS (System)

Green

  • On steadily—Junos OS for EX Series switches has been loaded on the switch.

  • Blinking (not applicable for EX4300-48MP and EX4300-48MP-S switches)—The switch is booting.

Unlit

  • EX4300 switches except EX4300-48MP and EX4300-48MP-S switches—The switch is powered off or is halted.

  • EX4300-48MP and EX4300-48MP-S switches—The switch is booting or the switch is powered off or is halted.

MST (Primary)

Green

In a standalone EX4300 switch:

  • On steadily—The switch is functioning normally.

  • Off—The switch is powered off or is halted.

In a Virtual Chassis configuration:

  • On steadily—The switch is the primary in the Virtual Chassis configuration.

  • Blinking—The switch is the backup in the Virtual Chassis configuration.

  • Off—The switch is a line card member in the Virtual Chassis configuration or is halted.

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

A minor alarm (yellow or 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.

Status LED

There are four LEDs for each port (labeled 2, 3, 4, and 5 in Figure 21). If a port is configured to operate at 10-Gbps speed by using breakout cables, four 10-Gbps interfaces are created and the four LEDs for that port becomes operational. Each of these LEDs indicates the link activity on the corresponding interface. If a port is configured to operate at 40-Gbps or 100-Gbps speed, the LED labeled 2 for that port in Figure 21 becomes operational and indicates the link activity on the corresponding port.

POE

Indicates the PoE mode. The status indicators are:

  • Steadily green—PoE is enabled on the port and a device is drawing power.

  • Blinking green—PoE is enabled on the port, but no power is drawn from the port.

  • Unlit—PoE is not enabled on the port.

Starting in Junos OS Release 20.1R1, you can use the request chassis beacon command on EX4300-48MP switches to identify the switch or a port on the switch. When you execute the command, the status LEDs on the RJ-45 network ports blink two times per second irrespective of the mode the ports are operating in (see How to Locate a Device or Port Using the Chassis Beacon).

Table 16 describes the Status LED on the ports on the 4-port 1-Gigabit Ethernet SFP/10-Gigabit Ethernet SFP+ uplink module for EX4300-48MP and EX4300-48MP-S switches.
