Revised: October 26, 2015, Cisco USC 8718/8818 Dual-Mode Small Cell Module Installation Before You Begin The Cisco Universal Small Cell (USC) 8718 dual-mode small cell module provides either 3G or 4G cellular coverage in an indoor environment where improved coverage and capacity is desired for cellular services. The USC 8818 small cell module provides LTE cellular coverage on a software-selectable LTE band.
These small cell modules enable mobile operators to offer dedicated, in-building coverage and capacity for UMTS and LTE services. They are managed by the Cisco USC 8088 controller installed in the enterprise.

Installation Considerations Install your small cell: • in a central location, in an area where people are most likely to make calls • away from windows, to avoid the signal leaking outside or external signals leaking in • in an open area with airflow; not in a closed cabinet which reduces the signal strength • at least 5 meters (16 feet) from an external wall. This distance maximizes indoor coverage and minimizes RF leakage outside the building.
Procedure Step 1 Step 2 Step 3 Remove the module from the packaging. Power down the access point if you are installing the small cell module into an operational access point. Peel off the label from the back of the AP to reveal the module port connector.
Step 4 Align the module connector with the connector on the back of the AP or USC 5030 chassis such that the male and female 100-pin mezzanine connectors mate. Figure 3: Installing Module in the Cisco 5030 Chassis Step 5 1 Small cell module 4 10/100 Base-T Ethernet port 2 Openings for module antennas 5 Power port for DC power source 3 Port connector Hold both units in your hands and firmly join the module to the AP or USC 5030 chassis to fully attach the two units.
Because the small cell module is thicker than the AP, you must hold both units together when attaching them. Screw down the thumb screws on the module. Note If the screws are not tightened, the module will not be recognized and may not operate correctly. Make sure not to over-tighten the screws; they should be only hand-tightened. Power up the access point. If necessary, mount the access point or USC 5030 chassis, with the small cell module installed, using the universal bracket (AIR-AP-BRACKET-2).
Boot Sequence and USC 8088 Controller Communication On initial boot, the small cell module performs the following boot sequence. When finished, the module is reachable. Figure 4: Small Cell Boot Sequence Boot Sequence: 1 When the small cell is powered on, the device sends a DHCP Request to the controller DHCP server to get IP information. The DHCP server is configured on the controller to respond only to DHCP requests from Cisco Systems small cells.
5 The arrival sequence begins. The controller sends the software image to the small cell. 6 The small cell boots up the received software package. 7 The small cell establishes an IPsec tunnel with the controller. Based upon the radio configuration, the small cell loads the appropriate protocol elements and joins the network.
