Never expose the module’s components to Electrostatic Discharge: Make sure you have attached the module’s disposable grounding strap to your wrist and always place the module on a non-conductive surface.

Unpacking the Module

1.Carefully remove the module from the shipping box. (Save the box and packing materials in the event the module must be reshipped.)

2.Remove the module from the plastic bag. Observe all precautions to prevent damage from Electrostatic Discharge (ESD).

3.Carefully examine the module, checking for damage. If any damage exists, DO NOT install the module. Contact Cabletron Systems Technical Support immediately.

The Module’s Physical Layout

The 9A426-02 Module has two major circuit boards on which components are attached (see Figure 2-1). The module’s base-level circuit board is known as the motherboard. The module’s second-level circuit board is known as the daughterboard. The removable daughterboard attaches to the motherboard’s connectors and standoffs. Both the motherboard and the daughterboard contain components that are accessible to the user.
