NOTE
Tighten the screws of this module before you insert additional modules. Otherwise, you might unseat
modules that you have not secured.
10 Store the module packaging for future use.
Leave the ESD strap permanently connected to the chassis so that it is always available when you need
to handle ESD-sensitive components.

Verifying the SMMi Installation

After you install the SMMi, verify that it is working correctly by checking the LEDs on the front panel
of the module. If it is operating normally, the front-panel LED indicators appear as follows:
• STATUS LED—green blinking
• DIAG LED—off
• PSU A, B, or both LEDs—green
For more information about SMMi LED activity, see "SMMi LEDs" on page 176.

Replacing SMMi Modules

All Alpine 3800 series modules (SMMi and I/O modules) are hot-swappable. You do not need to power
off the system to remove a module.
You need the following tools and equipment to replace an SMMi module:
• ESD-preventive wrist strap
• # 1 Phillips screwdriver
• Antistatic packaging
• Replacement SMMi module
To remove an SMMi module:
1 Attach the ESD strap to your wrist and connect the metal end to the ground receptacle on the top
right corner of the switch front panel.
2 Use a #2 Phillips screwdriver to unscrew the two captive screws.
3 Simultaneously rotate the ejector/injector levers away from the center of the module to disengage
the module from the backplane.
4 Slide the module out of the chassis. Hold the module front panel with one hand, and place your
other hand under the metal panel to support the module.
