Important Requests on Protection from Lightning Strike
If you connect a network camera, a wireless access point, or other devices that can be
affected by a lightning strike (in particular, devices installed outdoors) to the twisted pair
port of this Ethernet Switch, a lightning surge current/voltage may be conducted to this
Ethernet Switch through the twisted pair cable, leading to malfunction. If you connect such
device, it is strongly recommended that you install a surge protective device (SPD) on the
twisted pair port side of this Ethernet Switch.
A lightning surge current/voltage may be conducted to this Ethernet Switch through the
power supply or ground wire connected to the power port, leading to malfunction. If a
lightning surge current/voltage may flow in through the power supply or ground wire, it is
recommended that you install a surge protective device (SPD) on the power port side of this
Ethernet Switch.

CAUTION
Be careful when performing the following operations since the device will be at high
temperatures immediately after it has been energized or the power has been shut off.
- Relocating the installation area, transporting, and attaching, and removing
attachment brackets, etc.
- Connecting and disconnecting twisted pair cables, fiber optic cables, SFP modules and console cables
- Attaching, and removing power cords
- Operating LED display change buttons
Deviation could lead to injuries or burns, etc. because of high temperatures.
Do not connect any other devices except for
10BASE-T/100BASE-TX/1000BASE-T devices to the twisted pair ports.
Deviation could lead to equipment failure.
Do not insert any other modules into the SFP expansion slots except for our
optional SFP modules (PN54022/PN54024).
Deviation could lead to equipment failure.
Check our website for the latest information on supported SFP modules.
Do not connect the console ports with any other device except for Serial
communication terminal.
Deviation could lead to equipment failure.
To connect a power receiving equipment supporting IEEE802.3at to this
Ethernet Switch, use a cable rated Cat5e or higher.
Using other cables may result in heat generation, ignition, and/or equipment failure.
It is strongly recommended that a lightning arrester (SPD) be installed on the
twisted pair port side and the power supply side of this Ethernet Switch.
Malfunctions might be caused due to overcurrent or overvoltage from the
effects of lightning strikes.
