Replacement Procedures
Caution Never disconnect the interconnect cable while the system is operating (except when
replacing a redundant DSC card) because you will lose all calls.
Figure 5-15 Connecting the Dial-Shelf Interconnect Cable
Warning The ports labeled Network clock, 10BaseT, Dial Shelf Interconnect, Console, and Alarms
are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits. Because the E1/T1 circuits are treated like telephone network
voltage, avoid connecting the SELV circuit to the telephone network voltage circuits.
For more information about the dial-shelf interconnect cable and dial-shelf interconnect port adapter,
see the “Replacing a Dial-Shelf Interconnect Port Adapter” section on page 5-27.
