3.5 Stacking Using Interface Card on Rear Panel
You can connect up to 8 switches to form a stack with a single management IP address. Follow the steps below to connect the switches and configure the stack ports, then the switches will automatically elect a master unit and establish a stack. Once the stack is established, you can use any port of any switch in the stack to manage the stack system.
You can use either the SFP+ ports on the front panel or the Interface Card on the rear panel to create a stack. These two pairs of stack ports cannot be mixedly used in the stack connection.
Here we take stacking using Interface Card for example.
1. Install an Interface Card (TX432 for example) into the Interface Card Slot of each switch, see 3.4 Installing & Removing the Interface Card.

Lightning Protection
Chapter 4 Lightning Protection
4.1 Cabling Reasonably
In the actual network environment, you may need cable outdoors and indoors, and the requirements for cabling outdoors and indoors are different. A reasonable cabling system can decrease the damage of induced lightning to devices.
Note: Its not recommended using Ethernet cables outdoors. When cabling outdoors, please use a signal lightning arrester.
Requirements for Cabling Outdoors Aerial cabling without safeguard is not allowed.
Its not allowed cabling down the building to connect network devices in different floors.
Outdoor cables should be buried and paved to the indoor through basement. A piece of steel wire should be paved underground along the pipe and connected to the lightning protection terminal of the building for shielding. Before connecting the cable to the device, install a signal lightning arrester on the corresponding port.
When an aerial cable is set up, the cable should be through a metal pipe (15m long at least) before coming into the building. The two ends of this metal pipe should be grounded. Before connecting the cable to the device, install a signal lightning arrester on the corresponding port.
Its not necessary to pave STP cables through pipes. The shielded layer of STP cable should be well grounded. Before connecting the cable to the device, install a signal lightning arrester on the corresponding port. Requirements for Cabling Indoors
When cabling indoors, keep a certain distance away from the devices that may cause high-frequency interferences, such as down-conductor cable, powerline, power transformer and electromotor.
The main cable should be paved in the metal raceway of the access shaft. When cabling, keep the loop area formed by the cable itself as small as possible.
15
Stackable L2+/L3 Managed Switch
Requirements for the distance between Ethernet cable and other pipelines are shown in the table.
Other Pipelines Ethernet Cable

The two diagrams below demonstrate parallel net length and parallel-overlapping net height.
Note: The above minimum net length/height is required when metal raceway is not used. If any requirements cannot be met, you can add a steel tube or metal raceway for shielding.
Requirements for the distance between Ethernet cable and high-power electric devices are in following tables.

4.2 Connect to Ground
Connecting the device to ground is to quickly release the lightning over-voltage and over-current of the device, which is also a necessary measure to protect the body from electric shock.
In different environments, the device may be grounded differently. The following will instruct you to connect the device to the ground in two ways, connecting to the grounding bar or connecting to the ground via the power cord. Please connect the device to ground in the optimum way according to your specific operation environment.
Connecting to the Grounding Bar If the device is installed in the Equipment Room, where a grounding bar is available, you are recommended to connect the device to the Grounding Bar as shown in the following figure.

Note: The figure is to illustrate the application and principle. The power cord you get from the package and the socket in your situation will comply with the regulation in your country, so they may differ from the figure above.
If you intend to connect the device to the ground via the PE (Protecting Earth) cable of AC power cord, please make sure the PE (Protecting Earth) cable in the electrical outlet is well grounded in advance.
4.3 Equipotential Bonding
Equipotential Bonding is the practice of intentionally electrically connecting all earthed systems to the same grounding grid or connecting the grounding grids of all the earthed systems together through the ground or overground metal so as to create an earthed equipotential zone. When lightning occurs, the high voltage produced by lightning current in all systems will meanwhile exist in their ground cables, and thus all ground cables have the same electrical potential and basically eliminate the electric strikes between the systems.
The figure bellow illustrates how to practice equipotential bonding in a network.
