Locating the Serial Number on an EX4300 Switch or Component

If you are returning a switch or hardware component to Juniper Networks for repair or replacement, you must locate the serial number of the switch or component. You must provide the serial number to the Juniper Networks Technical Assistance Center (JTAC) when you contact them to obtain Return Materials Authorization (RMA).

If the switch is operational and you can access the CLI, you can list serial numbers for the switch and for some components with a CLI command. If you do not have access to the CLI or if the serial number for the component does not appear in the command output, you can locate the serial number ID label on the physical switch or component.

Note:

If you want to find the serial number on the physical switch component, you will need to remove the component from the switch chassis, for which you must have the required parts and tools available. See Installing and Removing EX4300 Switch Hardware Components.

Listing the Switch and Components Details with the CLI

To list the switch and switch components and their serial numbers, enter the following CLI command:

show chassis hardware

The following output lists the switch components and serial numbers for an EX4300-48P switch:

The following output lists the switch components and serial numbers for an EX4300-48MP switch:

Locating the Chassis Serial Number ID Label on an EX4300 Switch

The serial number ID label is located on the rear panel of the chassis on EX4300 switches. Figure 1 shows the location of the serial number ID label on 24-port and 48-port EX4300 switches except EX4300-48MP and EX4300-48MP-S switches. Figure 2 shows the location of the serial number ID label on EX4300-48MP and EX4300-48MP-S switches. Figure 3 shows the location of the serial number ID label on 32-port EX4300 switches.

Locating the Serial Number ID Labels on FRUs in an EX4300 Switch

The power supplies, fan modules, and uplink modules, installed in EX4300 switches are field-replaceable units (FRUs).

For each of these FRUs, you must remove the FRU from the switch chassis to see the FRU’s serial number ID label.

  • Power Supply—The serial number ID label is on the top of the power supply. Figure 4 shows the location of the serial number ID label on an AC power supply used in EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, Figure 5 shows the location of the serial number ID label on an AC power supply used in EX4300-48MP and EX4300-48MP-S switches, and Figure 6 shows the location of the serial number ID label on a DC power supply. EX4300-48MP and EX4300-48MP-S switches do not support DC power supply. SeeRemoving an AC Power Supply from an EX4300 Switch and Removing an AC Power Supply from an EX4300 Switch.

  • Uplink modules

    • EX4300 switches except EX4300-48MP and EX4300-48MP-S switches—Figure 9 shows the location of the serial number ID label on the QSFP+ uplink module, Figure 11 shows the location of the serial number ID label on the 4-port SFP+ uplink module, and Figure 12 shows the location of the serial number ID label on the 8-port SFP+ uplink module.

    • EX4300-48MP and EX4300-48MP-S switches—Figure 10 shows the location of the serial number ID label on the 2-port 40-Gigabit Ethernet QSFP+/100-Gigabit Ethernet QSFP28 uplink module (model number: EX-UM-2QSFP-MR) and Figure 13 shows the location of the serial number ID label on the 4-port 1-Gigabit Ethernet SFP/10-Gigabit Ethernet SFP+ uplink module (model number: EX-UM-4SFPP-MR) for EX4300-48MP and EX4300-48MP-S switches.
