14 CHAPTER 2: INSTALLATION

Data Port

Connections

The PRISM 3111 is equipped with either a V.35 port (on a standard 34-pin

connector) or an EIA-530 port (on a standard 25-pin connector). The PRISM 3112

is available with two ports. Pin functions for the high speed port interface are

listed in Table 2-7.

FCC rules require that interconnecting cables carrying high speed data be shielded

appropriately in order to minimize radio frequency interference.

Power Connection

The PRISM 3111/3112 can be powered by either an AC or DC suppy. When

power is applied to the unit, the front panel indicators flash for approximately five

seconds as the unit initializes. The green power LED on the front panel will

remain illuminated as long as the unit receives power.

AC Power

AC powered units use a 115 VAC captive power supply. There is no power switch.

Per UL 1950 and CSA 950 Clause 1.7.2, if the power supply cord is intended to

serve as a disconnect device, a socket must be installed near the equipment and be

easily accessible.
