QFX5241-64OD and QFX5241-64QD Management Panel

QFX5241-64OD and QFX5241-64QD Management Panel

The management panel is located in the front panel of a QFX5241-64OD or QFX5241-64QD switch. You can find the management panel to the right of the port panel. Apart from the 64 network ports in the ports panel, both the QFX5241-64OD and QFX5241-64QD switches offer the following ports in the management panel:

  • Two SFP28 Ports—Supports data transmission speeds of up to 10 Gbps using SFP28 transceivers. The SFP28 ports are numbered 64 and 65.

  • One USB 3.0 port—Primarily used for storage and file transfers. For example, use this port to connect a USB drive to perform upgrades, export configuration files, or save log files.

  • One RJ-45 console (CON) port—Provides direct serial communication with the switch to support tasks such as initial configuration, troubleshooting, and recovery.

  • One RJ-45 management (MGMT) port—Supports out-of-band management of the switch. The typical use cases include secure management, remote management, monitoring, and logging.

QFX5241-64OD and QFX5241-64QD Management Panel LEDs

The management panel in the QFX5241-64OD and QFX5241-64QD switches has the following LEDs:

  • Chassis Status LEDs

  • Management port LEDs

  • SFP28 port LEDs

The following sections explain how to interpret these LEDs.

QFX5241-64OD and QFX5241-64QD Chassis Status LEDs

The QFX5241-64OD and QFX5241-64QD switches have three LED types that indicate system status. You can find these LEDs to the right of the network ports (see Figure 3 and Figure 4).

SYS—System status

  3

RST—Reset button. You can find the reset button beneath the ID LED. The reset button is not a status LED, although it is located in this panel.

Note:

When you use the reset button, the device reboots. However, the existing configuration of the switch does not change. That is, the device does not return to the factory-default configuration.

ALM—Chassis alarm or fault

ID—Serves as a locator or identification indicator for the switch

You can view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis led:

Table 1: Chassis Status LEDs on QFX5241-64OD and QFX5241-64QD Switches

Name

Color

State

Description

ALM (Alarm)

Unlit

Off

The switch is halted, or there is no alarm.

Note:

The ALM LED glows green during BIOS booting.

Red

On steadily

A major hardware fault has occurred, such as a temperature alarm, power failure, or media failure. The device has halted.

Use the CLI commands show chassis alarms, show system alarms, and show system errors active detail to gather information about the error that triggered the alarm. This information helps to decide the recovery steps to perform.

To troubleshoot, perform the following:

  1. Power off the device by setting the AC power source outlet to the off (O) position or by unplugging the AC power cords.

  2. Correct any voltage or site temperature issues, and allow the switch to cool down.

  3. Power on the device.

  4. Monitor the PSU LEDs and fan module LEDs to determine where the error is occurring.

Amber

On steadily

A minor system level alarm has occurred, such as a software error or a missing rescue configuration.

Use the CLI commands show chassis alarms, show system alarms, and show system errors active detail to gather information about the error that triggered the alarm. This information helps to decide the recovery steps to perform.

To troubleshoot, perform the following:

  1. Power off the device by setting the AC power source outlet to the off (O) position or by unplugging the AC power cords.

  2. Power on the QFX5241-64OD and QFX5241-64QD switches.

  3. Monitor the status LEDs to ensure that Junos OS Evolved boots properly.

SYS (System)

Unlit

Off

The device is powered off or halted.

Note:

The SYS LED glows green during BIOS booting.

Green

On steadily

Junos OS Evolved is loaded on the device.

ID (Identification)

Unlit

Off

The beacon feature is not enabled on the device. Enable this feature by using the request chassis beacon fpc 0 on operational mode command.

Note:

The ID LED glows green during BIOS booting.

Blue

Blinking

The beacon feature is enabled on the device. Disable this feature by using the request chassis beacon fpc 0 off operational mode command.
Tip:

To know the status of the beacon, use the show chassis beacon operational mode command:

user@host> show chassis beacon
    OFF

Management Port LEDs

The RJ-45 management port on the QFX5241-64OD and QFX5241-64QD switches has two LEDs that indicate link status and link activity. The management port is labeled MGMT.
