Install the router after you have completed the installation preparations.
The router can be installed:
• On a workbench
• In a cabinet
Installing the Router on a Workbench
In many circumstances, you may not own a 19-inch standard rack. Usually, the router will be installed on
a clean workbench. The operations are very simple, but still, you should be aware of the following items:
• Ensure the stability and well-grounding of the workbench.
• Reserve a space of 10 cm (3.9 in.) around the router for heat dissipation.
• Do not place heavy objects on the router to avoid extruding the device and affecting heat
dissipation performance.
Installing the Router in a Cabinet
You can install an MSR 20 router in a 19-inch standard cabinet, such as an H3C N68 rack. For the
installation of an N68 rack, refer to N68 Cabinet Installation Guide.
