Mounting an EX8208 Switch on a Rack or Cabinet Using a Mechanical Lift

Because of the switch's size and weight, we strongly recommend using a mechanical lift
to install the switch.
NOTE: For instructions on installing a switch without using a mechanical lift,
see "Mounting an EX8208 Switch on a Rack or Cabinet Without Using a
Mechanical Lift" on page 137.
CAUTION: Do not install line cards in the chassis until after you mount the
chassis securely on a rack or cabinet.
CAUTION: Before front-mounting the switch on a rack or cabinet, have a
qualified technician verify that the rack or cabinet is strong enough to support
the switch's weight and is adequately supported at the installation site.
Before you install the switch:
Prepare the site for installation as described in "Site Preparation Checklist for an
EX8200 Switch" on page 85.
Ensure the site has adequate clearance for both airflow and hardware maintenance
as described in "Clearance Requirements for Airflow and Hardware Maintenance for
an EX8208 Switch" on page 95.
Unpack the switch as described in "Unpacking an EX8200 Switch" on page 120.
In a two-post rack, install the power cord tray at the desired position (see "Installing
the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch" on page 129). The lip
of the power cord tray will support the front of the chassis when you install the switch
in the two-post rack.
In a four-post rack, install the adjustable mounting brackets at the desired position
(see "Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200
Switch" on page 126). Optionally, you can also install the power cord tray and use it to
manage the power supply cords.
Review chassis lifting guidelines described in "Chassis Lifting Guidelines for EX8200
Switches" on page 282.
Ensure that you have the following parts and tools available to install the switch:
A mechanical lift
24 mounting screws appropriate for your rack
A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack
mounting screws
