the lower subboard port of the ISUA board can hold only the FE optical subboard,

while the lower subboard port of the ISUE board can hold only the 4-port FE electrical

subboard.

The ISU board resides in slots 14 and 15 of the MA5600 service frame. One service

frame can hold up to two ISU boards working in the active/standby mode.

4.3.3 Subboards

The ISU board provides the upper and lower subboard slots, where,

For the ISUA board, the upper slot can hold the FE or GE optical subboard, while

the lower slot can hold only the FE optical subboard.

For the ISUE board, the upper slot can hold the FE or GE optical subboard, while

the lower slot can hold only the 4-FE-electrical-port subboard.

4.6.4 DIP Switches of Subboard

The E8IT subboard (IMA service subboard) is of two types: E8IT.2 REV.0 and E8IT.2

REV.A.

The E8IT.2 REV.0 subboard supports only the 75-ohm coaxial cable.

The E8IT.2 REV.A subboard supports both the 75-ohm coaxial cable and the

120-ohm twisted pair by setting the DIP switches.

Both types of E8IT subboards have five sets of DIP switches (S1S5), where,

S5 has four bits.

S1, S2, S3, and S4 have eight bits each.

The port impedance of the E8IT.2 REV.0 is 75 ohms by default, you need not

configure it.

Table 4-14describes the settings of DIP switches.
