Installing an Intraconnect Module in an EX4500 Switch

If you removed the intraconnect module from an EX4500 switch, use the procedure described in this topic to install the intraconnect module.

The intraconnect module is installed horizontally on the rear of the switch. See Rear Panel of an EX4500 Switch.

Note: Operating an EX4500 switch without the intraconnect module is not supported.

Before you begin installing the intraconnect module in an EX4500 switch:

• Ensure that you have taken the necessary precautions to prevent ESD damage (see Prevention of Electrostatic Discharge Damage on EX Series Switches).
• Have instructions and tools available for removing and installing the fan tray. If the fan tray is installed, you must remove it as part of the procedure for installing the intraconnect module. After you install the module, you must install the fan tray. See Removing a Fan Tray from an EX4500 Switch and Installing a Fan Tray in an EX4500 Switch.

Ensure that you have the following parts and tools available:

• Electrostatic discharge (ESD) grounding strap
• Phillips (+) screwdriver, number 2
• A replacement intraconnect module

Note: You must remove the fan tray from the EX4500 switch before installing the intraconnect module. See Removing a Fan Tray from an EX4500 Switch.

To install an intraconnect module in the switch (see Figure 1):

1. Ensure that the power is disconnected from the switch:
   • If the AC power source outlet has a power switch, set it to the OFF (0) position.
   • If the AC power source outlet does not have a power switch, gently pull out the male end of the power cord connected to the power source outlet.
2. Ensure that the fan tray has been removed from the switch. See Removing a Fan Tray from an EX4500 Switch.
3. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
4. Taking care not to touch module components, pins, leads, or solder connections, remove the intraconnect module from its bag.
5. Loosen the captive screws on the front faceplate of the module using the Phillips screwdriver.

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

7. Using both hands, place the intraconnect module in the empty slot and slide it in until it is fully seated.
8. Tighten the captive screws using the screwdriver.
9. Reinstall the fan tray in the switch chassis. See Installing a Fan Tray in an EX4500 Switch.
10. Connect power to the switch. See Connecting AC Power to an EX4500 Switch.

When the Status (ST) LED on the intraconnect 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 uplink module. It does not apply if you replace these components with the same type of component.
