Connecting Cables to the 5160
When connecting cables to the 5160, always make only one connection at a
time. Ciena recommends that cables be connected in the following order:
• Synchronization cable first
• GPS cables next
• Fiber cables next
• Ethernet cables last
Note: The alarm cable can be connected before, during or after the
installation of the other cables. See “Alarm Cable” on page 2-12 for more
information about the alarm cable. See “Installing an Alarm Cable
(Optional)” on page 2-25 for a procedure.
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.
Note: When two Ethernet ports are connected, the devices will
automatically assign the transmit and receive ports.
Alarm Cable
The alarm cable is an optional component.
The 5160 supports 16 external alarm inputs. The alarm connector is located
in the center/right section of the 5160 labeled ALARMS. The 15 foot alarm
cable has a high density 26-pin D-sub connector on one end, and bare wires
on the other. These wires are then connected to a wire wrap panel.
Of the 26 pins on the connector, there are 16 return sense connections to
detect switch close or opens and 8 returns. Up to two alarm sense lines can
be connected to each return. The alarm sense lines can be paired with any
return, however, it is recommended that the sensed switches that are paired
come from equipment that is commonly grounded. The alarm pinout is
provided in Table 2-2 on page 2-13.
