Installing an RE Module in an EX8216 Switch

You can install either one or two Routing Engine (RE) modules in an EX8216 switch. The RE modules install horizontally in the front of the chassis in the slots labeled RE0 and RE1. See Slot Numbering for an EX8216 Switch.

Note: We recommend that you install two RE modules for redundancy. If you install only one RE module, we recommend that you install it in the slot RE0.

Caution: Do not lift the RE module by holding the ejector levers. The levers cannot support the weight of the module. Lifting the modules by the levers might bend the levers, and the bent levers will prevent the RE module from being properly seated in the chassis.

Before you begin installing an RE module in an EX8216 switch:

• Ensure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

Ensure that you have the following parts and tools available to install an RE module:

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

To install an RE module in an EX8216 switch (see Figure 1):

1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Taking care not to touch the leads, pins, or solder connections, pull the RE module out from the bag.
3. Pull both the ejector levers outward, away from the faceplate of the RE module, until they go no further.
4. If the slot has a cover panel on it, unscrew the two screws on either side of the cover panel counterclockwise using the Phillips (+) screwdriver, number 2. Remove the cover panel. Save the cover panel for later use.
5. Carefully align the sides of the RE module with the guides inside the chassis.
6. Ensuring that the RE module is correctly aligned, carefully slide it into the chassis until you feel resistance.
7. Push both the ejector levers towards the faceplate of the RE module until the levers are flush against the faceplate and are fully engaged.
8. Tighten the screws, one on each side of the RE module, by turning them clockwise using the Phillips (+) screwdriver, number 2. Ensure that the RE module is fully seated in the chassis. It must be fully seated in order for it to be powered up.
9. Verify that the RE module is installed correctly and functioning normally by checking the LEDs on the faceplate of the RE module. The ON LED and ST LED should be lit steady green a few minutes after the RE module is installed.

   If the ON LED is unlit, verify that there are enough power supplies installed. See Calculating Power Requirements for an EX8216 Switch. If more power supplies are needed, install additional power supplies. See Installing an AC Power Supply in an EX8200 Switch or see Installing a DC Power Supply in an EX8200 Switch. If there are enough power supplies in the switch, remove and install the RE module again. See Removing an RE Module from an EX8216 Switch.

   If the ST LED is lit steady yellow, the RE module has failed. Remove the module and install a new RE module. See Removing an RE Module from an EX8216 Switch.
