Connecting the
FireWire
After the RM and PEM AC power cords are connected, connect the
FireWire(s). Connect each PEM to the RM making sure the connection is
securely connected. Note that the ferrite end must be connected to the
RM as shown.
When adding a PEM to an existing RAS 1500 system, connect the PEM
AC power cord before connecting the FireWire cable. Connecting the
FireWire cable before the AC power cord may cause existing calls to shut
down when AC power is applied.
