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.
2. Log in to the GUI of each switch, go to Stack→Stack Management→Stack Config page to
enable the stack mode of port M1 and M2 (port 1/1/1 and 1/1/2 on the GUI). Remember to click
Save Cong after the configuration.
3. Power off the switches, and then connect a 10G SFP+ cable (TXC432-CU1M/TXC432-CU3M of
TP-Link for example) between each pair of Interface Cards among the switches, thus forming a

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:
It's 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.
■It’s 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.
■It’s 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.

JetStream Stackable L3 Managed Switch
15Lightning Protection
■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.
■Requirements for the distance between Ethernet cable and other pipelines are shown in the table.
