1) Fix the rack on the ground, stable and level; and ground the device well.
2) Fix L-shaped brackets to the device with screws. (Shown as below)
Figure 2.2 L-shaped bracket installation
3) Adjust the device to a nice height and fix the device to the rack with screws (self-prepared). (Shown as below)
Figure 2.3 Fix to the rack
Desktop-mounting
Also, you can install the device on a desktop.
1) Place the device bottom on a stable and flat desktop.
2) Paste the four footpad stickers to the corresponding four corners of the device bottom.

ST-POE16 / ST-POE24 USER MANUAL

Figure 2.4 Paste the footpads
3) Then place the device correctly on the desktop.
2.3 Grounding
Grounding is not only important for lightning arresting and anti-interference, but for your own personal safety.
Please select the proper method to ground your device.
With grounding bar
If a grounding bar is available at the installation site, follow either of the two installations to ground the device.
A. Connect to the Grounding Bar Directly
1) Connect one end of the grounding cable to the binding post on the grounding bar.
2) Connect the other end of the grounding cable to the grounding terminal and fix the screw.
Figure 2.5 Connect to the grounding bar

ST-POE16 / ST-POE24 USER MANUAL

B. Connect to another grounded device
1) Connect one end of the grounding cable to the grounding terminal of the grounded device and fix the screw.
2) Connect to the other end of the grounding cable to the grounding terminal of the device and fix the screw.
Figure 2.6 Connect to a grounded device
Cautions
Connect the grounding cable to the earth ground system in the equipment room. Do not connect it to a fire main or
lighting fixture.
Without grounding bar
If there is no ground bar but earth ground nearby and the grounding body is allowed to be buried, follow
below steps:
1) Bury an angle steel or steel pipe (≥0.5m) into the earth.
2) Weld one end of the grounding cable to the angle steel or steel pipe and embalm the welding point.
3) Connect the other end of the grounding cable to the grounding terminal and fix the screw.

ST-POE16 / ST-POE24 USER MANUAL
16
Figure 2.7 Ground with an angle steel
If both ground bar and the conditions for burying the grounding body are not available, an AC-powered
Ethernet switch can be grounded using the PE (Protecting Earth) wire of the AC power supply.
Figure 2.8 Ground with 3-core AC power cord
Cautions
Make sure that the PE wire of the AC power supply has been well grounded at the side of the power distribution
room or AC power supply transformer.

Chapter 3 Physical Connection
3.1 Connect to RJ45 Ports
Connect the switch to a remote device with Ethernet cable via RJ45 port. G1 and G2 are uplink ports. Ports
1-16/24 support IEEE 802.3af and IEEE 802.3at PoE supply, and the PD can be wireless AP, IP phone or IP
camera, etc. By default, PoE features of Ports 1-16/24 are enabled.
Figure 3.1 RJ45 port connection
Note that:
1. Cat 5e or better Ethernet cable is recommended. As each RJ45 port supports MDI/MDIX auto-negotiating,
either parallel or crossover cable is available.
2. The device supports dynamic PoE supply. Namely, the device will power the PD properly and automatically.
