To install an intraconnect module in the switch (see Figure 65 on page 215 ):
1. Ensure that the power is disconnected from the switch:
If you are using AC power:
•
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 plug end of the
power cord connected to the power source outlet.
If you are using DC power:
•
Open the input circuit breaker so that the cables will not become active during the installation process.
2. If the fan tray has not been removed from the switch, remove it. See “Removing a Fan Tray from an
EX4500 Switch” on page 190 . Set it aside so that you can install it after you install the replacement
intraconnect module.
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 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.
6. Using both hands, place the intraconnect module in the empty slot and slide it in until it is fully seated.
7. Tighten the captive screws using the screwdriver.
8. Reinstall the fan tray in the switch chassis. See “Installing a Fan Tray in an EX4500 Switch” on page 192 .
9. Connect power to the switch. See “Connecting AC Power to an EX4500 Switch” on page 128 or
“Connecting DC Power to an EX4500 Switch” on page 131 .
When the status (ST) LED on the intraconnect module turns green, the module is ready for use.
