Rack-Mounted Installation
We recommend that you use a standard EIA distribution rack. See “Equipment
Rack Requirements” on page 133 for detailed rack information.
Installation Guidelines
Before installing the systems in a rack, consider the following
guidelines and refer to Figure 15:
You can install up to 3 ERX-14xx models, 6 ERX-7xx models, or 14 ERX-310
routers in a single 7-ft. (2.1 m) rack.
Installing multiple systems in a single rack enables you to maximize your
