Connector pins #2 and 52 (+3.3V) are connected in common, both should connect to the host system power rail. Connector pins #4, 9, 15, 18, 21, 26, 27, 29, 34, 35, 40, and 50 are connected in common, all should connect to the host system ground. 4.2 LED Indicator Functions Name Functional Description Dock LED Steady flashing when dock power is applied and radio is beaconing but not connected to a host. LED is solid when a wireless connection is made to a Host PC. Security LED Normally off, Flashes during cable association process, Goes solid when a successful cable association is made. During wireless operation, this LED is off when there is not wireless connection to a host, when successful Secure wireless connection is made to a pre-associated host, the LED goes solid. Data LED Flashes when data is being passed wireless in either direction. Host Connect LED Normally off. The LED goes solid when a wireless connection is made with the host. This "Host Connect" LED indicates that the dock is successfully connected to the host. Table 2. LED Indicator Functionality

UG- HS6621 _1.0 P.6/6 6.0 Mechanical The HS6621 PCB is designed to allow the user to optionally choose one of two mechanical envelopes: 1. Full Minicard, this is PCB standard PCB configuration. 2. Half Minicard configuration. This optional configuration is achieved by removing the inert top one-half of the PCBA, a score line is provided on the PCB to facilitate this action in production. This should not be considered a field-changeable option. Recommended connector: Molex 67910-0002 PCI Express Mini Card Connector with Molex 48099-4000 PCI Express Mini Card Latch.
