Cisco ONS 15454, Hardware Installation Manual

Page: 259 / 516

In addition to supplying power to the ONS 15454 M2 shelf, the power modules support the following
connections:
• LAN Connection—An Ethernet port (RJ-45) that supports the element manager system (EMS) connection.
The RJ-45 port is used to connect the EMS or the craft interface terminal to access the ONS 15454 M2
shelf.
• Passive Unit Inventory Interfaces (USB port)—The passive unit inventory interfaces are used to retrieve
inventory information from passive devices such as, fiber trays, FBG DCU, patch panels, passive
muxponder and demuxponder and so on. The inventory details are displayed in the
Inventory tab in
CTC.
• Timing Connections—The BITS-IN port receives input from third party external sources called SSU
(Synchronization Supply Unit) to synchronize the timing of the ONS 15454 M2 shelf. The BITS-OUT
port provides output to external devices (other Cisco or third party shelves) to synchronize the timing
signals with the ONS 15454 M6 shelf.
The ONS 15454 M2 shelf has a BITS-IN and BITS-OUT port on the power module. The BITS-IN and
BITS-OUT connections are supported by:
• Wire-wrap pins and mini-BNC connectors on the AC power module. •
• Mini-BNC connectors on the ETSI DC power module.
• Wire-wrap pins on the ANSI DC power module.
For timing connection, use 100-ohm shielded BITS clock cable pair #22 or #24 AWG (0.51 mm² [0.020 inch]
or 0.64 mm² [0.0252 inch]) twisted-pair T1-type.
Note
Refer to Telcordia SR-NWT-002224 for rules about provisioning timing references. Note
AC Power Module
The AC power module converts the AC input current to DC output current.
Each AC power module has:
• One AC single phase three poles (line L, Neutral N, and Protective Earth PE) input connector
• One RJ-45 port for EMS connection
• One USB port to support passive unit remote inventory connection
• Two BITs connections (IN and OUT) for network synchronization supported by mini BNC
• Two BITs connections (IN and OUT) for network synchronization supported by four wire-wrap pins
The AC power module has a single dual-color (red and green) LED on the faceplate. When the AC power
line is not connected, the LED is OFF. Green LED indicates that the AC power line is connected and the
power module is functioning properly. Red LED indicates that the AC power line is connected but an alarm
is present due to secondary (48 V) fuse break. The shelf controller card controls the conditions that result in
triggering the LED. The LED can be overwritten by the shelf controller card (TNC, TNCE, TSC, TNCS-2,
TNCS-2O, or TSCE) in all the three states (OFF/red/green). The AC power module supports the lamp test
procedure and the LED changes its color or state. The fans in the ONS 15454 M2 shelf cool the AC module
and guarantee proper operation across the complete operating temperature or output power range.
