•
Ensure the rack or cabinet can support the weight of the switch and other
additional weight.
Positioning the Switch
The switch is equipped with Power Supply Units (PSU) and hot-swappable fan modules.
It is important to determine the airflow direction of the power supply and fan modules
before installing the switch.
Each fan module handle/plug retainer is color-coded to indicate its airflow direction.
 Red: indicates front-to-back airflow (air inlet module). See “Front-to-Back Airflow”.
 Blue: indicates back-to-front airflow (air outlet module). See “Back-to-Front Airflow”.
To ensure proper airflow, make sure that when you install the switch its air intake is
positioned in a cold aisle and the air exhaust is positioned in a hot aisle for your data
center.
NOTE:
•
Verify that each module has the same airflow direction. Make sure the switch runs
with all of its power supply and fan tray modules taking in air from a cold aisle
and exhausting air to the hot aisle.
Rack Mounting the Switch
You can install the switch in most standard 19-inch (48.3-cm) racks.
CAUTION
•
Due to the switch’s weight, it should be installed by at least two people.
Items Required for Installation
The following items are required to install the switch onto the rack:
•
Phillips screwdriver
•
Screws that fit the equipment rack
