Switch ground wire is the first guarantee of anti-thunder and anti-
interference of the switch. It is required that users must connect the
ground wires correctly.
AC noise filter is connected to the AC input end of switch power
supply, whose center is connected with chassis. The chassis ground
(that is protect ground) must be connected to the ground, so as to
make induction electricity and leaked electricity flow to the earth
and improve the feature of anti electromagnetic interference.
For external network connection such as E1 interface, grounding
cable protects the PSTN. The grounding wire also protects the
thunder high voltage from the external network connection such as
E1 interface and PSTN.
Connect this point and ground it by a thick cable with resistance not
bigger than 4Ω. If the switch is installed on 19-inch standard cabinet,
the cabinet should be grounded.

065-7434 Signamax 24-Port 10/100 L3 switch adopts stable power
supply switch system and has a low requirement for input AC. It
supports 220V and 50Hz AC, which is a civilian electricity standard.
Different areas have different power supply systems.
The input power supply requirements of 065-7434 Signamax 24-
Port 10/100 L3 Switch are as follows:
AC: 100-240V, 50/60Hz
DC: -40--57V (the devices without POE function)
DC: -46--57V (PoE power supply, the devices with POE function)
When connecting power supply, use the below suggested power
supply jack or MIM PC power supply jack for reliable grounding.
When laying cables for buildings, the ground wires of the power
supply system have been installed underground. Users should
ensure the reliable grounding and make the corresponding
processing.
The input wire of the DC power supply is the private three-core DC
wire. Use the furcated lug to connect the American Standard DC
socket (8.25 distance and M3 crimp screw).
The connection method is as follows:
