Installation Guide

10. Visually inspect the alignment of the router. If the router is installed properly in the rack, the mounting screws on one side of the
rack should align with the mounting screws on the opposite side and the router should be level. Add all remaining screws.
NOTE
For better grounding of the router to the rack, attach the router using star washers. You should also use star washers
with any single-hole grounding lugs to keep the lugs from rotating.
Installing your MLXe-32 outer in a 4-post EIA rack
You can install the MLXe-32 routers in a 4-post EIA rack using the optional 4-post rack mount kit available from Extreme Networks. The
table below lists the contents of this kit.

NOTE
Because of the weight of fully loaded 32-slot routers, it is recommended that you mount the router in the EIA rack before
installing modules and power supplies.
You will need the following items to install your 32-slot router in a 4-post EIA rack:
• A mechanical lift tted with a lift plate (instead of forks) to move the device o the pallet and transport it to the rack. The lift
should be rated for 500 lbs. minimum.
• A strap to secure and stabilize the device while it is being moved on the mechanical lift.
• Screws to attach the rails to your EIA rack type. (These are usually provided with the EIA rack.)
DANGER
Do not attempt to lift an ExtremeRouting MLX-32 chassis. It is extremely heavy. REMOVE THE POWER SUPPLIES AND
INTERFACE MODULES FIRST (management, switch fabric, and all line cards). Use a mechanical lifting device to lift the
chassis. Four or more people are required to position the unpopulated chassis into the rack.
CAUTION
To prevent damage to the chassis and components, never attempt to lift the chassis using the fan or power supply handles.
These handles were not designed to support the weight of the chassis.
Before installation, plan the location and orientation of the device relative to other equipment in the rack. For cooling purposes, allow a
minimum of six inches of space between the front and back of the device, and walls or other obstructions.
Because you will need to use a mechanical lift to move and install the device, make sure you allow enough space to operate the lift. You
will also need at least two people to slide the router o the lift and into the rack.
