Chapter topics include shipment verification, site preparation, and equipment unpacking. Note Cisco does not recommend shipping equipment that is mounted in racks. To ship equipment from one site to another, pack the equipment in the original box. The storage period should not exceed 12 months. Store the packed equipment indoors in a well-ventilated and static-safe environment. The label displays information in alphanumeric bar code format.

This application is typically used for very large end customers or in a building with many smaller end customers. The ONS can be connected towards the backbone network via fiber, radio, or copper.
The unit may support many different CPEs and may also support different types of transmission media. The unit is the interface between the core network and the access network. It is also possible to connect equipment from other vendors to the ONS Typically an internal ONS is used to groom traffic from several ONS s that are connected to the access network.
The internal ONS is connected to the core network. The fan unit is a plug-in device consisting of a circuit board with four fans. The air is sucked in via four circular openings in the left sidewall and emerges via holes in the right side cabinet wall.
Four fans are used to improve reliability. These act as the main and standby fans. The "main" and "stand-by" designations are swapped every 24 hours to evenly distribute wear on the fans. In case of an abnormal temperature rise, all fans will operate simultaneously. The fans operate in pairs; there are two standby fans and two main fans. The maximum temperature measured in the ONS controls the fans. The only modules not containing temperature sensing are the fan unit itself, the power modules, and the system controller card.
The FAN module is connected to the main card through the backplane. The alarm, specific for each fan, is processed and presented as a Fan Failure Alarm.
It also supports two alarm outputs used to signal equipment alarms and traffic related alarms. The module has features that allow power sharing and hot plugging. The secondary current is short circuit proof and the average s. The maximum secondary current is limited to ab.
A 3m long power cable is also provided with a Mini-fit connector in one end and no connector in the other end. This cable connects the ONS to the internal 48V power-rails inside the rack. The cable and the power supply meet the safety requirements of the EN specification. The amount of memory can be configured at the factory from 64 MB to MB. The software is stored in Flash memory devices.
The 32 MB CompactFlash is mounted in a connector on the system controller. The module contains the local synchronization interface for the ONS This interface is directly connected to the SETS functionality on the motherboard.
The interface supports a framed E1 interface. It is possible to select different overhead bytes from all SDH interfaces to the 30 available time slots. The physical connectors of the five interfaces are of the RJ type.
The fifth LED indicates the status of the management port. Power consumption for the system controller module is 23 W maximum. The interface is running at a data rate of The synchronization port is used for SETS functionality on the main card.
The proprietary protection interface will be used for equipment protection in a future release. The power consumption should not exceed 23W. The module is equipped with a reset circuit that resets the card in case of a fault in one of the voltages.
Note The reset switch that is accessible in front of the system controller module will reset the ONS A special tool such as a small screwdriver or a pencil may be used to activate the switch.
Cisco ONS 15305 Installation and Operations Guide
Page Installing The Ons The shelf assembly is allocated for installation in a in. You need two 1-RU extension brackets for this procedure. The brackets The V power interface of ONS is galvanically insulated from the cabinet. The positive pole of the V supply 0 VDC shall always be connected to the same earth potential at the station battery on the PDP side. Failure to do so can result in injury or death. This will cause condensators inside the module to charge.

Note Be sure that the power cable is connected and verify the correct polarity. Verify that it is properly fused 1. Note Note that the ONS power cannot be switched off with a separate power switch. Note The power supply has been connected correctly when the green LED is on.

The product is typically used for high-bandwidth service delivery to medium-sized and large businesses, and for traffic aggregation at small central offices. Ethernet connections over the SDH infrastructure can be point-to-point or multipoint. The Cisco ONS can be configured with up to four plug-in service modules which may vary depending on which application will be implemented. Figure 1.
