Juniper EX9208 Hardware Guide

•
Unpack the switch as described in “Unpacking the EX9200 Switch” on page 155.
•
In a four-post rack or open-frame rack, install the mounting shelf. See Installing a
Mounting Shelf in a Rack or Cabinet for an EX9204 Switch, “Installing a Mounting Shelf
in a Rack or Cabinet for an EX9208 Switch” on page 162, or Installing a Mounting Shelf
in a Rack or Cabinet for an EX9214 Switch.
•
Review chassis lifting guidelines described in Chassis Lifting Guidelines for EX9200
Switches.
Ensure that you have the following parts and tools available to install the switch:
•
A mechanical lift
•
7/16-in. (11-mm) nut driver
•
Phillips (+) screwdrivers, number 1 and 2
•
ESD grounding wrist strap
CAUTION: If you are installing more than one switch in a rack or cabinet,
install the first switch at the bottom of the rack.
To install the switch using a mechanical lift:
1. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD
point on the chassis.
2. Ensure that the rack or cabinet is placed in its permanent location and is secured to
the building. Ensure that the installation site allows adequate clearance for both
airflow and maintenance.
3. Load the switch onto the lift, making sure it rests securely on the lift platform.
4. Using the lift, position the switch in front of the rack or cabinet, centering it in front of
the mounting shelf installed in the rack.
5. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the mounting
shelf and position it as close as possible to the shelf.
6. Carefully slide the switch onto the mounting shelf so that the bottom of the chassis
and the mounting shelf overlap by approximately two inches.
Slide the switch onto the mounting shelf until the mounting brackets contact the rack
rails. The shelf ensures that the holes in the mounting brackets of the chassis align
with the holes in the rack rails.
7. Move the lift away from the rack.
8. Install a mounting screw into each of the open front-mounting holes aligned with the
rack, starting from the bottom.
9. Visually inspect the alignment of the switch. If the switch is installed properly in the
rack, all the mounting screws on one side of the rack are aligned with the mounting
screws on the opposite side and the switch is level.
