Preparing and Installing
the 9A426-02 Module
This chapter describes the physical layout of the 9A426-02 Module and explains
how to prepare and install the module in a SmartSwitch 9000 chassis.
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.
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.
