Returning the QFX5700 Switch Chassis or Components

Locating the Serial Number on a QFX5700 Switch Chassis or Component

If you are returning a QFX5700 field-replaceable unit to Juniper Networks for repair or replacement, you must locate the serial number of the switch or field-replaceable unit. You must provide the serial number to the Juniper Networks Technical Assistance Center (JTAC) when you contact them to obtain a Return Materials Authorization (RMA).

If the QFX5700 is operational and you can access the command-line interface (CLI), you can list serial numbers for the switch and some components with a CLI command. If you do not have access to the CLI or if the serial number for the field-replaceable unit does not appear in the command output, you can locate the serial number ID label on the switch or field-replaceable unit.

Note:

If you want to find the serial number ID label on a component, you need to remove the component from the chassis, for which you must have the required parts and tools available.

Note:

You must remove the fan module to read the fan serial number from the serial number ID label. The fan module serial number cannot be viewed through the CLI. Fan Tray 2 refers to the third module from the left, counting from 0.

Listing the QFX5700 Chassis and Component Details by Using the CLI

To list the QFX5700 and components and their serial numbers, use the show chassis hardware CLI operational mode command.

Here is a sample of the CLI output for the QFX5700:

Locating the QFX5700 Chassis Serial Number ID Label

The serial number ID label is located on a label on the top cover.

Locating the Serial Number ID Labels on QFX5700 Components

For each field-replaceable unit, you must remove it from the chassis to see the serial number ID label. See Figure 1.

  • AC power supply—The serial number ID label is on the top of the AC power supply. See Figure 2.

  • DC power supply—The serial number ID label is on the top of the DC power supply. See Figure 3.

  • Fan module—The serial number ID label is on the top of the fan module. See Figure 4.

Returning a QFX5700 or Component for Repair or Replacement

If you need to return a QFX5700 or component to Juniper Networks for repair or replacement, follow this procedure:

  1. Determine the serial number of the component.
  2. Obtain a Return Material Authorization (RMA) number from the Juniper Technical Assistance Center (JTAC) as described in Contact Customer Support to Obtain Return Material Authorization.
    Note:

    Do not return any component to Juniper Networks unless you have first obtained an RMA number. Juniper Networks reserves the right to refuse shipments that do not have an RMA. Refused shipments are returned to the customer through collect freight.

  3. Pack the switch or component for shipping.

For more information about return and repair policies, see the customer support page at https://www.juniper.net/support/guidelines.html.

Contact Customer Support to Obtain a Return Material Authorization

If you need to return a device or hardware component to Juniper Networks for repair or replacement, obtain an RMA number from JTAC. You must obtain an RMA number before you attempt to return the component.

After locating the serial number of the device or hardware component you want to return, open a service request with the JTAC on the Web or by telephone.

Before you request an RMA number from JTAC, be prepared to provide the following information:

  • Your existing service request number, if you have one

  • Serial number of the component

  • Your name, organization name, telephone number, fax number, and shipping address

  • Details of the failure or problem

  • Type of activity being performed on the device when the problem occurred

  • Configuration data displayed by one or more show commands

You can contact JTAC 24 hours a day, seven days a week, on the Web or by telephone:

Note:

For international or direct-dial options in countries without toll free numbers, see https://support.juniper.net/support.

If you are contacting JTAC by telephone, enter your 12-digit service request number followed by the pound (#) key for an existing case, or press the star (*) key to be routed to the next available support engineer.

The support representative validates your request and issues an RMA number for return of the component.

Packing a QFX5700 Chassis or Component for Shipping

If you are returning a QFX5700 chassis or component to Juniper Networks for repair or replacement, pack the item as described in this topic.

Before you pack the chassis or component:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Retrieve the original shipping carton and packing materials. Contact your JTAC representative if you do not have these materials, to learn about approved packing materials (see Contact Customer Support).

Ensure that you have the following parts and tools available:

  • ESD grounding strap.

  • Antistatic bag, one for each component.

  • If you are returning the chassis, an appropriate screwdriver for the mounting screws used on your rack.
