MP7500 Router Installation Manual Version 1.0
If LINK light flashes, it means that there is loopback on the circuit.
If STATE light is off/on, it means that the channelized POS high-speed
interface board does not work normally.
Grounding Wire Connection
The normal connection of MP7500 ground wire is the first guarantee of
anti-thunder and anti-interference of the router. It is required that users
must connect the ground wires correctly.
AC noise filter is connected to the AC input end of router 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 4
Ω
. If the router is installed on 19-inch standard cabinet, the cabinet
should be grounded.
Connecting Power Supply
MP7500 router adopts stable power supply switch system and has a low
requirement for input AC. In China, adopt 220V and 50Hz AC, which is a
civilian electricity standard. Different areas have different power supply
systems.
MP7500 router input power supply requirements are as follows:
AC input power supply: 100-240V, 50/60Hz
DC input power supply: -40--57V
Maximum power: 2×350W
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.
