eHub Advance- Hardware Description

eHub Advance

The eHub Advance is a rugged and compact network appliance that is designed for use in industrial applications. It can be mounted horizontally or vertically (wall-mount) and the orientation will not affect its function. For best performance, the eHub Advance should be mounted so that ambient or flowing air can pass across the heatsink fins. As there are no fans, the eHub Advance does not have an active cooling system and convection cooling is the primary means of removing heat from the device.

The EF200is expandable in function through the use of USB dongles and adapters. Please consult the applicable Help Guides or contact e3 Systems for expansion options.

Power Button and Power States

The eHub Advance has 3 power states: On, Off and Sleep. The Sleep state is not widely used.

To turn the device On: Press the power button once.

To turn the device Off: Hold the power button for 5 seconds. Wait a minimum of 5 seconds before turning the device On again.

To Reboot the device: There is no physical reboot/reset button on eHub Advance. To reboot/restart the eHub Advance from the On state, Press and hold the power button for 5 seconds, release the power button. wait 5 seconds, then press the power button once.

The following table details the procedure to switch between each of the three power states.

LED Indicators

The eHub Advance has 3 LEDs to indicate the power state and function of the device.

Power Protection Reset and Cycling Behavior

The eHub Advance has an integrated Power Protection circuit that protects the device from intermittent and inconsistent power. This circuit requires removing power for a certain ‘lock-out’ period of time so that the eHub Advance may reset and recognize that external power has been reapplied.

Power Cycling Example Behavior Diagrams

Users may notice different behavior when cycling DC and AC power to the eHub Advance. The behavior can be explained in two ways:

1. The eHub Advance has a few product variations with slightly different startup power behavior. These include differences in power management implementation based on manufacture date [which is not a parameter trackable by Device ID (DID)] and processor differences. Both variables change the power consumption and power lock-out time constant.

2. Different use cases have associated power hold-up and power lock-out times. The following diagrams show the power cycling behavior and timing in 2 different cases: cycling DC power and cycling AC power.

For all variants of the device, following these guidelines will have predictable behavior:

Power Cycling Behavior Explained

Disconnecting DC power from eHub Advance

• Cuts the DC voltage to eHub Advance

• eHub Advance runs from internal DC capacitance

• eHub Advance internal DC capacitance drains within 3 seconds

Disconnecting AC/DC adapter from AC Power Source (Mains)

• AC/DC Adapter capacitance maintains +12VDC

• eHub Advance runs from internal DC capacitance and external AC/DC adapter capacitance

• eHub Advance drains internal and external capacitance within 30 seconds

Device ID (DID) and Serial Number

Each device is assigned a unique Device ID (DID) and Serial Number. These identifiers are used for inventory management, registration, and customer support. The DID contains key hardware and manufacturing information, allowing customers and internal teams to identify the device model and configuration.

Device IDs are 17 characters long and follow the following format.

Example of an DID is - EF1G5AABCDEAABBCC

Description

Type Code

The first two characters of the DID represent the Type Code, which identifies the product model. Type Code of the eHub Advance Model is EF.

Revision

Third character Revision is a single character that indicates the hardware revision of the device.

Manufacturer Code

Fourth character shows the Manufacturer Code. Refer the manufacturer codes below. In this example, G denotes the device was manufactured by GLiNet.

Date

The next two characters denote the date - years from 2020 + month.

For example:

Configuration

The next 5 characters denotes the configuration. These 5 characters are unique to each Model.

Serial Number

The last 6 characters are the serial number of the device.
