Warning
KS-type system telephones are powered through the C and D wires. Take the nec-
essary precautions to avoid short circuits at the interconnect block. If a short circuit
occurs between wires C and D, the interface’s protection will take the extension out
of service. To activate the extension again, remove the short, disconnect the system
telephone then reconnect it. The interface should then start operating normally.
Important
When there are more than 4 optiPoint 500 (Master or Slave) telephones on the Hi-
Path 1120 system, an additional power supply must be used. (see Chapter 3, “List
of modules”).
