About this task
Attention: To avoid rail failure and potential danger to yourself
and to the unit, ensure that you have the correct rails and fittings for your rack. If your rack has
square support flange holes or screw-thread support flange holes, ensure that the rails and fittings
match the support flange holes that are used on your rack. Do not install mismatched hardware by
using washers or spacers. If you don’t have the correct rails and fittings for
your rack, contact your reseller.
To install the rack-mounting hardware into the rack, complete the following steps:
Procedure

(4). Secure the rail to the rack by installing one M5x10L screw and one
washer (square hole rack) or one M5x10L screw (round hole rack) through the top hole in the rack
flange and into the rack rail.
