Physical connections to the components
See “Diagnostic port and cable pinouts” on page C-1 for detailed information about
the pinouts on the console serial port.
Alarm input port
This port is present on the COP, IP2000, and control modules. The DB-15 connector
can accept connections to monitor the alarm status of up to seven external devices. In
stand-alone Stinger CR ATM DSLAM units with an IP2000 module or control
module, a connection to this port is used to monitor the enclosure door alarm. In
these units, a special cable connects the switch for the enclosure door alarm to pins
one and two of this port.
Note
In hosted Stinger CR ATM DSLAM units, the door alarm switch is connected
directly to the door alarm pins on the chassis card-cage, behind the cooling module.
The ALARM port of the COP module is not used to monitor the door alarm. (see
“Chassis door alarm connections” on page C-20.)
Alarm connections for monitoring multiple external alarms
The ALARM port of an IP2000 or control module can be used to monitor multiple
devices. The connection for each external device consists of a pair of 24-gauge to
28-gauge connectors. One connector supplies ground, and the other senses the status
of the remote alarm by applying 3.3Vdc, which draws less than 10mA of current
through the closed contacts of the alarm relay on the remote device. For the
complete pinout arrangement of the DB-15 connector, see “Alarm input port
pinouts” on page C-3.
Note
This capability is generally not used on Stinger CR ATM DSLAM installations.
Alarm connection for monitoring the enclosure door alarm
When the Stinger CR ATM DSLAM is configured as a stand-alone unit with an
IP2000 module or control module, a connection to the ALARM port is used to
monitor the enclosure door alarm. A special cable, provided with the unit, connects
the enclosure door alarm switch to pins one and two of this port. For additional cable
details, see “Door alarm connection for stand-alone operation” on page C-20.
To connect to the enclosure door alarm:
■
Connect The male DB-15 connector of the Stinger CR ATM DSLAM stand-alone
door alarm cable to the ALARM port connector of the IP2000 or control module.
■
On the opposite end of the cable, connect the spade connectors on the white and
black wires to the corresponding spade terminals on the door alarm micro switch,
as shown in Figure 3-28.
