Connecting Cables to the 5150
When connecting cables to the 5150, always make only one connection at a
time. Ciena recommends that cables be connected in the following order:
• Synchronization cable first
• Fiber cables next
• Ethernet cables last
Note: The alarm cable can be connected before, during or after the
installation of the other cables.
In order for two devices to communicate properly, the transmit ports on the first
device must be connected to the receive ports of the second device.
Alarm Cable
The alarm cable is an optional component
The 5150 supports 5 external closed contact alarm inputs. The alarm
connector is a D-sub 15 style connector in the center/right section of the 5150
faceplate labelled ALARMS. The 5150 uses a custom alarm connection, and
there are only 14 pins defined and used on both the connector and the alarm
cable. The 15 foot alarm cable has a D-sub connector on one end, and bare
wires on the other. These wires are then connected to a wire wrap panel.
The alarm port pinout is provided in Table 2-3.
See “To Install an Alarm Cable (Optional)” on page 2-26 for a procedure.
