CHAPTER 4: Installation
4. Installation
This chapter describes the functions of the 16-Port Managed Micro Rack (RM260)
chassis, tells how to install front and rear 2-Wire IDSL Line Driver Rack Cards into
the chassis, and how to connect to the twisted-pair interface and the serial
interface.
4.1 The Rack Chassis
The 16-Port Managed Micro Rack Chassis (Figure 4-1) has 16 card slots plus its own
power supply. Measuring only 3.5" high, the Rack Chassis is designed to occupy
only 2U in a 19" rack. Sturdy front handles allow the Rack Chassis to be extracted
and transported conveniently.

The power supply included in the Managed Micro Rack uses the same mid-plane
architecture as the modem cards. The front card of the power supply slides in from
the front, and the rear card slides in from the rear. They plug into one another in
the middle of the rack. The front card is then secured by thumbscrews, the rear
card by conventional metal screws.
WARNING
There are no user-serviceable parts in the power-supply section of the
Managed Micro Rack Chassis. Only qualified service personnel should
change the voltage settings and replace the fuses. Contact Black Box
Technical Support at 724-746-5500 for more information.
