Confirming installation preparations
Before you install a 7500 switch in a rack, verify the following items:
•
You have read the chapter "Preparing for installation" carefully and the installation site meets all
the requirements.
•
A 19-inch rack is ready for use. For how to install a rack, see the rack installation guide.
•
The rack is sturdy and reliably grounded.
•
The installation position on the rack is appropriate for the chassis.
•
No debris exists inside or around the rack.
•
The switch is ready for installation and has been carried to a place near the rack and convenient
for moving.
IMPORTANT:
To ensure the stability of the rack, mount the switch at the lowest possible position. To mount
multiple switches on the rack, mount the heaviest switch at the bottom of the rack.
Attaching slide rails and cage nuts to the rack
Installing slide rails
Before installing the switch to the rack, install slide rails to the rack. If the rack has slide rails, skip this
section.
Before installing the slide rails, verify that the slide rails can support the weight of the switch. For the
weights of the 7500 switches, see "Appendix A Chassis views and technical specifications."
As a best practice, order the HPE X421 A-Series Chassis Universal 4-Post Rack Mounting Kit
(JC665A). For more information about the kit, see "Appendix B FRUs and compatibility matrixes."
Make sure the rack meets the following requirements:
•
For all 7500 models, there is a minimum of 100 mm (3.94 in) of clearance between the front
rack posts and the front door for accommodating the cable management brackets.
•
For the 7502, there is a minimum of 440 mm (17.32 in) of clearance between the front rack
posts and the rear door for accommodating the chassis and power cord deployment.
Position the chassis of the 7500 switches according to their heights. For the specifications of the
7500 switches, see "Appendix A Chassis views and technical specifications."
The slide rail installation procedure varies by rack type The following installation procedure is for
your reference only.
To install a slide rail:
1.
Read the signs on the slide rails (see
) to avoid installation mistakes.
