Installing an SF Module in an EX8216 Switch

You can install up to eight Switch Fabric (SF) modules in an EX8216 switch. All shipping configurations of an EX8216 switch include eight SF modules. See EX8216 Switch Configurations.

The SF modules are installed vertically in the rear of the chassis in the slots labeled SF7 through SF0.

Note: You can install SF modules in any slot. You do not have to install the SF modules in serial order.

Note: Do not lift the SF module by holding the ejector levers. The levers cannot support the weight of the module. Lifting the module by the levers might bend the levers. Bent levers prevent the SF module from being properly seated in the chassis. Use the handle provided on the faceplate of each SF module to lift the module.

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

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

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

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

To install an SF module (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 SF module out from the bag.
3. Pull both the ejector levers outwards, away from the faceplate of the SF module, until they go no further.
4. Turn the SF module so that you can insert it in one of the vertical slots, then hold the handle with one hand and support the base of the SF module with the other hand as you align the SF module with the guides inside the chassis.
5. Ensuring that the module remains correctly aligned, slide the SF module into the chassis until you feel resistance.

   Ensure the ejector levers are engaged in the horizontal ejector rail. If the levers are not engaged, push the module’s faceplate just inside the hinges of the levers till the ejectors are engaged in the ejector rail.

6. Push both the ejector levers simultaneously towards the faceplate of the SF module until the levers are flush against the faceplate and are fully engaged.
7. Tighten the screws on each side of the SF module by turning them clockwise using the Phillips (+) screwdriver, number 2. Ensure that the SF module is fully seated in the chassis.
8. Verify that the SF module is installed correctly and functioning normally by checking the LEDs on the faceplate of the SF module. The ST LED and SF LED should be lit steady green a few minutes after the SF module is installed.

   If the ST LED is unlit, check whether 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 Installing a DC Power Supply in an EX8200 Switch. If there are enough power supplies in the switch, remove and install the SF module again. See Removing an SF Module from an EX8216 Switch.

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