Installing a Brocade MLXe-32 router
2
Installing a Brocade MLXe-32 router in a rack
DANGER
Make sure the rack or cabinet housing the router is adequately secured to prevent it from
becoming unstable or falling over.
DANGER
Mount the routers you install in a rack or cabinet as low as possible. Place the heaviest router at
the bottom and progressively place lighter routers above.
Because of the weight of a fully loaded Brocade MLXe-32 router, it is recommended that you install
the router in a rack before installing any modules and power supplies.
You can install one 32-slot router in a standard 19-inch 2-post or 4-post rack or open cabinet, in
either a front-mount position or a mid-mount position. You must provide eight standard #12-24
pan-head screws to secure the router in the rack. You will need a #2 Phillips screwdriver to perform
this task.
NOTE
Because of the weight of a fully-populated 32-slot chassis, it is not recommended that you install
your 32-slot router in a 2-post rack or open cabinet. The preferred installation is in a 4-post rack or
open cabinet. Refer to
“Installing your 32-slot router in a 4-post rack or open cabinet” on page 118
for installation instructions
Installation requirements
Allow 1 to 2 hours to complete this procedure. Your installation site must meet the following
requirements to ensure correct installation and operation:
• Provide 35 U of space in a 19 inch rack.
• Verify that the additional weight of the router does not exceed the weight limits for the rack or
the floor.
• Ensure that an electrical branch circuit with the following characteristics is available:
- Required voltage and frequency as indicated in the hardware reference manual.
- Protection by a circuit breaker in accordance with local electrical codes.
- Supply circuit, line fusing, and wire size that conform to the electrical rating on the router
nameplate.
- Grounded outlet compatible with the power cord and installed by a licensed electrician.
• Ensure that all equipment installed in the rack is grounded through a reliable branch circuit
connection. Do not rely on a secondary connection to a branch circuit, such as a power strip.
• Ensure that the rack is mechanically secured to support the router model.Ensure that the
airflow available at the inlet air vents does not exceed 40
o Celsius (104 o Fahrenheit).
• Only one 32-slot device can be mounted per rack, positioned as close to the bottom of the rack
as possible.
