The 9C300-1 Environmental Module is installed in the slot above the module card 
cage in the front of the MMAC-Plus chassis, as shown in Figure 2-1.

Install an Environmental Module by following the steps below:

1.

Unpack the Environmental Module by removing it from the shipping box and 
sliding the two foam end caps off the unit. (Save the shipping box and 
packing materials in the event the Environmental Module must be 
reshipped.)

2.

Remove it from the protective plastic bag. Observe all precautions to prevent 
damage from Electrostatic Discharge (ESD). (Save the bag in the event the 
Environmental Module must be reshipped.)

3.

Remove the plastic protective cap that covers the connector on the rear of the 
Environmental Module.

4.

Examine it carefully, checking for damage. If any damage exists, DO NOT 
install it. Immediately contact Cabletron Systems Technical Support. 

5.

Hold the left and right sides.

6.

Line up the rails on the left and right sides with the tracks on the left and right 
inside panels of the chassis.

7.

Slide the Environmental Module into the chassis until it is completely seated.

If the MMAC-Plus chassis has been powered up, the 9C300-1 Environmental 
Module illuminates the STATUS and ALARM LEDs and displays the name 
Cabletron on the LCD. 

If the LEDs are any color other than green, refer to LANVIEW LEDs in Chapter 3. 
If no keypad entries are made within 60 seconds, the LCD scrolls through various 
non-interactive mode screens.
