WARNING: Because of the switch's size and weight, we require the use of a
mechanical lift to install the switch.
CAUTION: If you are installing more than one switch in a rack, install the first
switch at the bottom of the rack.
CAUTION: Do not install line cards in the chassis until after you mount the
chassis securely on a rack.
Before mounting a J-EX8216 switch on a rack:
1.
Verify the site meets the requirements for installation described in “Site Preparation
Checklist for a J-EX8200 Switch” on page 63.
2.
Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure. See “Clearance Requirements
for Airflow and Hardware Maintenance for a J-EX8216 Switch” on page 73 for detailed
information.
3.
Unpack the switch as described in “Unpacking a J-EX8200 Switch” on page 98.
4.
Install the adjustable mounting brackets at the desired position in a four-post rack
(see “Installing Adjustable Mounting Brackets in a Rack or Cabinet for a J-EX8200
Switch” on page 103).
5.
Optionally, install the power cord tray, so you can use it to manage the power supply
cords (see “Installing the Power Cord Tray in a Rack or Cabinet for a J-EX8200 Switch”
on page 106).
6.
Read “General Safety Guidelines and Warnings for J-EX Series Switches” on page 201,
with particular attention to “Chassis Lifting Guidelines for J-EX8200 Switches” on
page 214.
Ensure that you have the following parts and tools available to mount the switch on a
rack:
•
A mechanical lift
• A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack
mounting screws
•
A flat-blade (-) screwdriver if you are installing the switch in a rack with square,
nonthreaded holes
• 20 mounting screws—and 20 cage nuts and washers if your rack requires
them—appropriate for your rack (provided)
