Typical CSS and Stack Deployment Networking Requirements At the core layer, two modular switches set up a CSS. At the aggregation layer, every two fixed switches set up a stack. The CSS at the core layer is connected to stacks at the aggregation layer through Eth-Trunk interfaces. Figure 2...
Scenario 2: The Stack System Operates on Access Switches This is the most common scenario when Layer 2 access switches set up a stack system, as shown in Figure 3-2. In this scenario, each switch in a stack connects to an aggregation device through Eth-Trunk. The stack system simplifies ...
GND (Exposed Pad Pin 25): The exposed pad must be soldered to the PCB to provide a low electrical and thermal impedance connection to the printed circuit board's ground. A continuous ground plane on the sec- ond layer of a multilayer printed circuit board is strongly recommended. 10 For ...
Physical Layer On the LTC6802-2, four pins comprise the serial inter- face: CSBI, SCKI, SDI and SDO. The SDO and SDI may be tied together, if desired, to form a single, bidirectional port. Four address pins (A0 to A3) set the part address for address commands. The TOS pin ...
Two stratum-3 time servers are available on the same layer-2 Ethernet. The internal system clock is connected to a dedicated real-time clock chip with a backup battery. A daemon process runs in the background to synchronize the system clock continuously; CLEAR uses systemd-timesyncd and ...

BLOND aims for long-term continuous measurements, which requires some fault tolerance in the transmission layer; rendering wireless or mesh-based networks unfit for this task. The building is equipped with spare Ethernet connections in each room, which were used as a reliable transmission network to...
In addition, pin 7, GND, is shorted to the exposed pad on the top layer. Enable Interface Figure 14 shows a simplified schematic of the EN pin interface. To enable the part, the applied EN voltage must be greater than 1.8V. If the enable function is not required, EN may be connected...
