Chapter 2 Setting Up the Cisco Unified IP Conference Station 7936 Installing the Cisco Unified IP Conference Station 7936 Using External Devices with Your Cisco Unified IP Phone Refer to this information when using external devices with your Cisco Unified IP Phone. • Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions: - Move the external device away from the source of the RF or AF signals. - Route the external device cables away from the source of the RF or AF signals. - Use screened cables for the external device, or use cables with a better screen and connector. - Shorten the length of the external device cable. - Apply ferrites or other such devices on the cables for the external device. • Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system will perform adequately when suitable devices are attached using good quality cables and connectors. Installing and Connecting to the Network You must connect the Cisco Unified IP Conference Station to the network and to a power source before using it. Refer to Figure 2-1 on page 2-17 and Figure 2-2 on page 2-18 when you are installing the Cisco Unified IP Conference Station. • Figure 2-1 shows the various components and power and cable connections used on the Cisco Unified IP Conference Station 7936. • Figure 2-2 shows the optional, external microphones and their connection to the external microphone jacks on the underside of the Cisco Unified IP Conference Station 7936. 2-16 Cisco Unified IP Conference Station 7936 Administration Guide OL-10751-01
