Confirming installation preparations
Before you install an S7500E 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.

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 S7500E series, see "Appendix A Chassis views and technical specifications."
H3C recommends that you order the H3C Slide Rail Accessories,500mm-800mm (LSTM2KSGD0).
Make sure the rack meets the following requirements:
• For all S7500E 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 S7502E, 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 S7500E series according to their heights. For the specifications of the S7500E
series, see "Appendix A Chassis views and technical specifications."
The slide rail installation procedure varies by rack type The following installation procedure is for your
