This appendix contains instructions for installing a preracked unit and contains the following sections:
The preracked Cisco MGC system consists of a customized assembly of hardware, firmware, and software that comes shipped from the Cisco factory as a racked unit. Figure A-1 is an example of a factory racked assembly consisting of a single rack and redundant MGC hosts.
Use the following checklist to make sure that you have all the equipment and components before you start installing the MGC hardware.
The following tables contain required hardware and components for preracked systems.

Make sure that you have the following tools before beginning the installation.
Your MGC hardware has been fully configured at the factory; no assembly is required. However, you will need the following tools and equipment to bolt your system to the floor:
Use the procedures in this section to bolt the factory racked system to the floor. A factory racked system ships from Cisco with all the hardware installed in a rack.
The Sun Netra t 1120 and Sun Netra t 1125 install in a standard 19-inches deep by 84-inches tall channel rack. The rack has two large L-shaped brackets (L brackets) mounted on the front and rear at the bottom of the unit that accommodate the floor mounting bolts. (See Figure A-2.)
 | Warning
Make sure that your rack is bolted to the floor. |
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
 | Warning
Make sure that your equipment rack is properly ventilated. |
Use this procedure to bolt the channel rack to the floor:
Step 1 Examine the area where the channel rack is to be bolted down. Make sure that this area has a thick and sturdy floor that can be drilled.
Step 2 Position the channel rack in the exact location where it is to be finally installed.
Step 3 Mark the mounting hole locations on the floor by tracing the L bracket screw hole positions.
Step 4 Move the channel rack away from this location.
Step 5 Drill the appropriate hole in the floor for the chosen anchor bolt size. The holes in the L brackets are 0.75 inches in diameter. Use the largest bolt size that will fit in this clearance hole. Cisco recommends using 0.62-inch diameter bolts, which are not provided.
Step 6 Install bolts into the holes that you drilled into the floor.
Step 7 Place the channel rack in the exact location where it is to be mounted to the floor by lining up the L bracket holes on the channel rack with the bolts installed in the floor.
Step 8 Insert large flat washers as a bearing surface under the heads of the anchor bolts.
Step 9 Install anchor bolts through the mounting holes into the bolts in the floor. Torque the bolts appropriately for the size of anchor bolt chosen.
This section applies to Sun E450 systems already rack-mounted in frames. Use these instructions to attach the Sun E450 in a Devtek Frame (frame #66-39-800-FRS) to the floor using the Devtek bolt-down kit (kit #66-00-000-BDK). The bolts and associated hardware attach to the frame and the frame attaches to the floor. This increases the safety of the installation by preventing the frame from tipping when the Sun E450s are extended on their slides.
The Devtek bolt-down kit contains the following hardware:
| Warning
Make sure that your rack is bolted to the floor. |
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
| Warning
Make sure that your equipment rack is properly ventilated. |
Use this procedure to bolt the frame to the floor:
Step 1 Examine the area where the frame is to be bolted down. Make sure that this area has a thick and sturdy floor that can be drilled.
| Warning Tilting the frame can cause the frame to drop with resulting bodily injury and property damage. At least two technicians are required for this procedure. Use caution in this process. Make sure that the Sun E450s are securely fastened to the frame prior to tilting the frame. |
Step 2 Tilt the frame and remove the wheels from the bottom of the frame. At the same time, remove the leveling feet. To remove the feet, unscrew them from the frame. (See Figure A-3.)
| Warning Sliding the Sun E450 forward will destabilize the frame unless it is held or secured in some manner. If the frame drops, it can cause bodily injury and property damage. |
Step 3 Slide the lowest Sun E450 forward while another technician holds the frame in a steady position.
Step 4 Attach the two L brackets from the bolt-down kit to the inside of the cabinet base structure. Secure each bracket with the three bolts provided. (See Figure A-4.)
Step 5 Position the frame in the exact location where it is to be finally installed.
Step 6 Mark the floor mounting hole locations by tracing the screw hole positions onto the floor.
Step 7 Carefully move the frame away from this location.
Step 8 Drill the appropriate hole sizes in the floor for the anchor bolt size chosen. The holes in the L brackets are 0.472 inches in diameter. Use the largest bolt size that will fit in this clearance hole. Cisco recommends using 0.375-inch diameter bolts.
Step 9 Install the bolts into the holes that you drilled into the floor.
Step 10 Place the frame in the exact location where it is to be mounted to the floor. Accomplish this by lining up the bracket holes on the frame with the holes drilled in the floor.
Step 11 Install anchor bolts through the mounting holes into the bolts in the floor. Torque the bolts appropriately for the size of anchor bolt chosen. Include large flat washers as a bearing surface under the heads of the anchor bolts.
