Ethernet switch 4 5 6 7 The Ethernet switch denoted with in Figure 7 is used for Ethernet connectivity and Local Area Network Internet Protocol (LAN IP) communications. The Ethernet switch has 16 10/100 Mb/s auto-speed Ethernet ports and built-in link and activity lights. Access to the switch is from the rear of the Radio Case.
QDBS–Broadband Hardware 1 2 3 4 4.2.6. RF antennas WARNING: When operating the QDBS–Broadband in pico-cell mode, install a 30 dB attenuator between the transmit port of the RAN CIP and the transmit antenna. Failure to install the attenuator may result in dangerous RF exposure and bodily harm. 5 6 7 For pico-cell operation, two small magnetic-mounted wire-whip RF antennas (one for transmitting and one for receiving), are provided with the QDBS–Broadband.
QDBS–Broadband Hardware 1 2 implements policies that determine which resources and services a valid user may access, and the accounting function keeps track of time and data resources used for billing and analysis. 3 4.3.2. Power Distribution Unit (PDU) 4 5 CAUTION: Turning off the components manually, using the PDU’s individual (numbered) switches may cause irreparable damage to the components.
QDBS–Broadband Hardware 1 Figure 10: RNC case (rear view) 2 3 4.3.5. Ethernet switch 4 5 6 The Ethernet switch denoted with in Figure 10 is used for Ethernet connectivity and LAN IP communications. The Ethernet has sixteen 10/100 Mbps auto-speed Ethernet ports and built-in link and activity lights. The switch is accessed from the rear of the RAN. 7 4.3.6.
QDBS–Broadband Hardware 1 4.3.7. Serial console 2 3 A serial console panel denoted with components of the Network Case. 4 4.3.8. 120V Convenience outlets 5 6 7 The 120 VAC outlets denoted with in Figure 10 provide power for additional equipment needed during the operation of the system. Typically, these outlets support a phone charger or a laptop power adapter. These outlets are not intended to supply power to any high wattage device.

Section 5 1 Setting Up the QDBS–Broadband 5.1. Site preparation 2 3 4 5 6 WARNING: Grounding the QDBS–Broadband to an appropriate ground is required to prevent injury or death in the event of a lightning strike. Depending on your deployment scenario, you can ground each QDBS–Broadband case grounding lug to facility ground by using grounding rods and cables, or ground to a vehicle-frame. Grounding equipment is not included with the QDBS–Broadband.
Setting Up the QDBS–Broadband 1 5.2.1. Setup sequence 2 3 See Figure 14 and Error! Reference source not found. for help on identifying the locations of items called out in the setup sequence. 4 To set up the QDBS–Broadband transit cases: 5 1. Press the red pressure relief valve on each case to relieve any pressure differences. 6 7 2. Remove the covers from the ends of the transit cases by unscrewing the captive threaded thumbscrews. 8 3.
Setting Up the QDBS–Broadband 1 Figure 14: Connections on the QDBS–Broadband 2 3 4 10. If the QDBS–Broadband is to be connected to a data network, connect the external network’s Ethernet cable to the PDSN port on the Radio Case CIP. 5 6 11. Connect both the Radio Case and Network Case AC power cables to a minimum of a 15A, 120V AC power supply. 7 5.3.
Setting Up the QDBS–Broadband 1 2 3 4 5 6 7 Frequency Electromagnetic Fields, 3 kHz to 300 GHz”" are being meet, when measured in accordance with the ANSI/IEEE C95.3-1992 “Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields - RF and Microwave” procedure. Exposure to excessive levels of RF radiation may cause serious bodily harm. 5.3.1. Pico-cell mode To connect a pico-cell antenna: 8 9 1.
Setting Up the QDBS–Broadband 1 2 do so may result in the antenna detaching from the mounting surface and seriously injuring personnel. 3 To connect a macro-cell antenna: 4 5 6 7 1. Connect the two macro-cell antennas (Transmit and Receive) to the desired mounting structure. NOTE: The two antennas should be at least five (5) feet apart for receive signal diversity. 8 9 2. Connect one end of the ½ inch diameter RF coax cable to bottom of the Transmit antenna. 10 3.
Section 6 Setting Up QDBS– Broadband Remote Radio Case(s) 1 2 3 The basic QDBS–Broadband system has a single Radio Case. This single Radio Case is capable of providing broadband coverage over a large geographic area. If more coverage is required, additional Radios may be connected to the QDBS–Broadband. 4 5 6 7 8 9 The initial Radio Case provided as a part of the basic QDBS–Broadband is referred to as a “local” Radio, since this Radio is physically in the same location as the Network Case.
