Replacing MSMs
Extreme Networks Consolidated "i" and "e" Series Hardware Installation Guide 261
To remove an MSM:
1 Attach an ESD strap to your wrist and connect the metal end to the ground receptacle on the top left
corner of the switch front panel.
2 To loosen the module, unscrew the screws with a #1 Phillips screwdriver.
3 Simultaneously rotate the ejector/injector levers outward to disengage the module from the
backplane.
4 Hold the module front panel with one hand, and place your other hand under the metal panel to
support the weight of the module.
CAUTION
To prevent ESD damage, handle the module by the metal panel edges only. Never touch the
components on the PCB or pins on any of the connectors.
5 Slide the module out of the chassis and place it immediately into an antistatic sack to protect it from
ESD damage and to prevent dust from collecting on the module’s connectors.
6 If you are installing a replacement MSM, follow the installation procedure described on page 257.
If you are not installing a replacement MSM, attach a cover plate over the empty MSM slot.
To remove additional MSMs, repeat steps 2 through 5.
Leave the ESD strap permanently connected to the chassis so that it is always available when you need
to handle ESD-sensitive components.
