Installing the Chassis in the Rack
The Acme Packet 3900 is now ready to be installed into a 4-post equipment rack. To
prevent personal injury or damage to the Acme Packet 3900, follow these guidelines:
•
This installation requires two people and should not be attempted otherwise.
•
Follow your organization’s best practices for lifting and installing heavy
components into an equipment rack.
•
Ensure that the Acme Packet 3900 chassis remains supported until you have
completely installed it into the equipment rack.
To install the Acme Packet 3900 chassis into the equipment rack:
1.
Lift the Acme Packet 3900 into the correct position to prepare to be installed into
the equipment rack.
2.
Line up the chassis slide rails in back of the chassis with the guides in front of the
equipment rack slide rails.
3.
If necessary, press in the latches on either side of the Acme Packet 3900 in order
for the assembly to slide into the guides.
4.
Push the Acme Packet 3900 fully into the equipment rack.
5.
Line up the chassis-mounted thumbscrews with the threads on the Acme Packet
3900 mounting spacer. You may have to adjust the spacer locations before they
line up with the Acme Packet 3900’s captive screws.
6.
Once correctly positioned, hand-tighten the thumbscrews into the mounting spacer
and secure the chassis in the rack.
7.
Torque the two captive thumbscrews using a #2 Phillips screwdriver.
8.
Torque all four #10-32 x 5/8” front screws that hold the slide rails to the rack.
