Installing a Virtual Chassis Module in an EX4550 Switch

You can install the Virtual Chassis module in either of the two module slots; one each on the front panel and the rear panel of the switch. Use the procedure described in this topic to install the Virtual Chassis module.

Before you begin installing the Virtual Chassis module in the switch:

Ensure that you have the following parts and tools available:

  • ESD grounding strap
  • Phillips (+) screwdriver, number 2

To install a Virtual Chassis module in the switch (see Figure 1):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Taking care not to touch module components, pins, leads, or solder connections, remove the Virtual Chassis module from its bag.
  3. If the module slot has a cover panel on it, remove the cover panel by using the screwdriver and save it for later use.
  4. Loosen the captive screws on the front faceplate of the Virtual Chassis module by using your fingers. If you are unable to loosen the captive screws by using your fingers, use the screwdriver.
  5. Using both hands, place the Virtual Chassis module in the empty slot and slide it in until it is fully seated.

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

  6. Tighten the captive screws by using your fingers or the screwdriver.
  7. Connect power to the switch. See Connecting AC Power to an EX4550 Switch or Connecting DC Power to an EX4550 Switch.

When the status (ST) LED on the Virtual Chassis module turns green, the module is ready for use.

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/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of power supply or add a new type of expansion module. It does not apply if you replace these components with the same type of component.
