Maintaining the Uplink Module in an EX3200 Switch

 

If your EX3200 switch includes an optional uplink module, it is installed in the switch's front panel. The different types of uplink modules are described in Uplink Modules in EX3200 Switches.

The uplink module in EX3200 switches is a hot-removable and hot-insertable unit (FRU): You can remove and replace it without powering off the switch or disrupting switch functions.

Before you begin removing an uplink module from the switch:

Ensure that you have the following parts and tools available:

  • Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available, follow the alternative grounding method described in Step 1 of the following procedure.)

  • Cross-head screwdriver (provided in the uplink module kit)

  • An antistatic bag or antistatic mat

To remove an uplink module from the switch:

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

    If a grounding strap is not available, touch the exposed, bare metal of the switch with the other hand to ground yourself and the component.

  2. Loosen the screws that secure the flip-up door covering the uplink module slot on the front panel of the switch by using the cross-head screwdriver provided with the uplink module kit and flip the door upward.
  3. Insert the ball end of the screwdriver in the keyhole on the front panel of the uplink module and slide the screwdriver to the narrow part of the keyhole (see Figure 1).Caution

    Ensure the screwdriver does not slip out of the keyhole when you pull the uplink module out of the switch chassis.

  4. Using both hands, gently pull the screwdriver to slide the uplink module halfway out of the chassis (see Figure 2).
  5. Place one hand under the uplink module to support it and slide it completely out of the chassis.
  6. Slide the screwdriver out of the keyhole.
  7. Place the uplink module in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

If your EX3200 switch includes an optional uplink module, you install it in the switch's front panel. The different types of uplink modules are described in Uplink Modules in EX3200 Switches.

The uplink module in EX3200 switches is a hot-removable and hot-insertable unit (FRU): You can remove and replace it without powering off the switch or disrupting switch functions.

Note

On an EX3200 switch, if you install an SFP uplink module or an SFP+ uplink module when the SFP+ uplink module is operating in the 1-gigabit mode, all the network ports from the last four built-in ports are disabled and remain disabled until you reboot the switch.

On an EX3200 switch, if you install a transceiver in an SFP uplink module or in an SFP+ uplink module when the SFP+ uplink module is operating in the 1-gigabit mode, a corresponding network port from the last four built-in ports is disabled. For example, if you install an SFP or SFP+ transceiver in port 2 on the uplink module (ge-0/1/2), then ge-0/0/22 is disabled. The disabled port is not listed in the output of show interface commands.

When an SFP+ uplink module is operating in 10-gigabit mode:

  • Only the 10-gigabit ports (ports 0 and 2) are enabled.

  • You can use only SFP+ transceivers in those ports.

When an SFP+ uplink module is operating in 1-gigabit mode:

  • All four ports are enabled.

  • You can use only SFP transceivers in all four ports.

Before you begin installing an uplink module in an EX3200 switch:

Ensure that you have the following parts and tools available:

  • Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available, follow the alternative grounding method described in Step 1 of the following procedure.)

  • Cross-head screwdriver (provided in the uplink module kit)

To install an uplink module in the switch (see Figure 3):

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

    If a grounding strap is not available, hold the uplink module in its antistatic bag in one hand and touch the exposed, bare metal of the switch with the other hand to ground yourself and the component.

  2. Loosen the screws that secure the flip-up door covering the empty uplink module slot on the front panel of the switch by using the cross-head screwdriver, flip the door upward, and remove the blanking panel covering the empty uplink module slot.Note

    If you are removing an uplink module and installing another uplink module, wait for at least 10 seconds after removing the uplink module before installing the new or the same uplink module. If you do not wait for at least 10 seconds, the interfaces on the uplink module might not come up.

  3. Taking care not to touch module components, pins, leads, or solder connections, remove the uplink module from its bag.Caution

    Before you slide the uplink module into the slot on the switch chassis, ensure the uplink module is aligned correctly. Misalignment might cause the pins to bend, making the uplink module unusable.

  4. Using both hands, place the module in the empty slot and slide it in gently until it is fully seated.
  5. Flip the door down and tighten the screws by using the cross-head screwdriver.
Note

If the switch does not detect the uplink module, see Troubleshooting Uplink Module Installation or Replacement on EX3200 Switches.

Note

If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
