Install an Interface Module

Up to eight interface modules can be installed in the Extreme 9920 chassis. An interface module is hot-swappable.

  • The following items are needed:

    • Phillips #2 screwdriver

    • Antistatic wrist strap

  • Visually inspect the connectors for damage before you insert the module.

    If you insert a module with damaged connectors you will damage the switch.

To prevent damage, use the following best practices when installing or handling modules:

  • Keep the modules on antistatic material when not in the chassis.

  • Avoid touching the components or connector pins.

  • Do not stack modules on top of each other outside of the chassis.

  • Always keep a module or a filler panel installed to maintain safety compliance, proper cooling, and EMI containment.

  • Do not overtighten screws or use a power tool to tighten screws.

Note

Note

Electrostatic discharge (ESD) can damage electronic circuits. Do not touch electronic hardware unless you wear a grounding wrist strap or other static-dissipating device.

  1. Open the package and verify the package contents.

    The package contains one interface module and this document.

  2. Remove the interface module from the box and then remove it from the anti-static bag.

    Handle the interface module by the edges and avoid touching the components or connector pins.
