Cable Tray Rack Mounting

To install the concentrator in a rack, first install the cable tray and then install the concentrator above the tray. The cable tray can be mounted in four separate configurations in your rack depending on your preference. The options are described in Table 2-2 and shown in Figure 2-2.
