Installing the MMAC-Plus modules

Chapter 2

The 9F310-02 and 9F315-02 modules occupy two slots in the MMAC-Plus chassis. The modules must be installed with the left side (as viewed from the front) in an odd numbered slot, and the right side in an even numbered slot.

NOTE

The INB Terminator Modules must be installed on the rear of the chassis before powering up this module. Refer to the INB Terminator Modules Installation Guide for information and installation procedure.

To install the 9F310-02 and 9F315-02, follow the steps below:

1.Switch off the power supplies and remove all power from the MMAC-Plus chassis.

2.Remove the blank panels, covering the slots that the module is being mounted in. All other slots must be covered, if modules are not being installed, to ensure proper airﬂow and cooling.

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

4.Attach one end of the ESD wrist strap packaged with the MMAC-Plus chassis to your wrist. Plug the other end into the ESD Wrist Strap Grounding receptacle in the lower right corner of the MMAC-Plus Chassis shown in Figure 2-1.

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

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

7.The modules are installed into the chassis by sliding them into slots and locking down both the top and bottom plastic tabs, as shown in Figure 2-1.Take care that the module slides in straight and engages the backplane connectors properly. When installing the module, ensure that both circuit cards are between the card guides, as shown in Figure 2-1.Check both the upper and lower tracks of both cards.
