Huawei SmartAX MA5608T Hardware Description

jumpers should be set to function at the same time. Table 3-34 describes the settings of J7, J8,
J9, and J10.
Table 3-34 Jumper settings for the NH1A daughter board
Status Description
ON (jumper
caps are
installed)
The jumper caps should be installed (which means grounded) if the
transmit and receive resistance is 75 ohms.
OFF (jumper
caps are
removed)
The jumper caps should be removed (which means ungrounded) if the
transmit and receive resistance is 120 ohms.
NOTE
Generally, the coaxial cables connected to the E1 port are unbalanced cables with the resistance of 75
ohms; the twisted pairs connected to the E1 port are balanced cables with the resistance of 120 ohms.
The interference source can affect the transmission of analog signals to a great extent. Therefore, the
connection mode and grounding mode must be correct and reliable; otherwise, bit error or error message
about signal loss may occur.
Daughter Board
To provide the related functions, the H801TOPA board must be configured with a matching
daughter board. Figure 3-61 shows the position of the daughter board (NH1A and EH1A) on
the H801TOPA board. Figure 3-62 shows the position of the daughter board (O2CE and
CSSA) on the H801TOPA board.
