• • • Working Environment – Before deploying the ESD Field Service kit, assess the situation at the customer location. For example, deploying the kit for a server environment is different than for a desktop or portable environment. Servers are typically installed in a rack within a data center; desktops or portables are typically placed on office desks or cubicles.
2 Technology and components This chapter details the technology and components available in the system. USB features Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheral devices like mice, keyboards, external drivers, and printers. Table 1. USB evolution Type Data Transfer Rate Category Introduction Year USB 2.0 480 Mbps High Speed 2000 USB 3.0/USB 3.1 Gen 1 5 Gbps Port SuperSpeed 2010 USB 3.
With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320 Mbps (40 MB/s) — the actual real-world maximum. Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps.
Alternate Mode USB Type-C is a new connector standard that is very small. It is about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use.
3. DisplayPort 1.4 – compatible with existing DisplayPort monitors, devices and cables 4. USB Power Delivery - Up to 130W on supported computers Key Features of Thunderbolt 3 over USB Type-C 1. 2. 3. 4. 5.
• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality. Power On and LED behavior with Fingerprint reader Power On and LED behavior with Fingerprint reader • • • • • • • • • Pressing the power button for a duration between 50 msec to 2 sec turns on the device. Power button does not register additional presses until the SOL (Sign-Of-Life) has been provided to the user. System LED's illuminates upon pressing the power button.
○ If the computer is connected to an electrical outlet, the battery light operates as follows: 1. Solid white -the battery is charging. When the charge is complete the LED turns off. ○ If the computer is running on a battery, the battery light operates as follows: • 1. Off -the battery is adequately charged (or the computer is turned off). 2. Solid amber -the battery charge is critically low. A low battery state is approximately 30 minutes or less of battery life remaining.
