2. Installation
CAUTION: Circuit devices are sensitive to static electricity, which can damage their delicate
electronics. Dry weather conditions or walking across a carpeted floor may cause you to acquire a static
electrical charge. To protect your device, always:
•Touch the metal chassis of your computer to ground the static electrical charge before you pick up the
circuit device.
•Pick up the device by holding it on the left and right edges only.
•If you need to connect an outdoor device to this device with cable then you must add an arrester on
the cable between outdoor device and this device.
Fig. Add an arrester between outdoor device and this switch
NOTE:The switch is an indoor device; if it will be used in an outdoor environment or
connects with some outdoor device, then it must use a lightning arrester to protect the switch.
W ARNING :
Self-demolition on Product is strictly prohibited. Damage caused by self-demolition will be charged
for repairing fees.
Do not place product outdoors or where sandstorms occur.
Before installation, make sure input power supply and product specifications are compatible to each
other.
To reduce the risk of electric shock, disconnect all AC or DC power cords to completely remove
power from the unit.
Before importing / exporting configuration please make sure the firmware version is the same.
After firmware upgrade, switch automatically moves configuration to latest firmware version.
Warning: this case must be grounded. No DC input may be grounded. The SM24TAT2DPA is compliant with 802.3at
in Environment A when using an isolated power supply. For 802.3at Environment B applications, use mid-span injector
(s), e.g. MIL-L100i, L1000i-at, between this switch’s PSE port and link partner PD port.
