Rack Mounting EarsEach DTC includes flush rack mounting ears as an integral part of the chassis. The rack mounting ears are utilized to flush mount the chassis in a 23” rack or 600mmx600mm ETSI rack. Additionally, separate forward mount ears are provided to allow the chassis to mount 1”, 2”, 5”, and 6” forward from the front of the 23” rack.

When the rack mount ears are in the 5” back and 6” back positions for a forward mount configuration, the DTC uses slack managers to route the fiber-optic cables. There are three slack managers on each side of the DTC (six total) which maximizes valuable rack space and help to eliminate the pinching of cable in addition to providing correct cable bend radius. This ensures the system’s continual integrity and protection against signal loss or degradation.

Fan TrayThe DTC contains two removable fan trays. Each fan tray consists of three individually controlled fans. The top fan tray is referred to as Fan Shelf A, and the bottom tray is referred to as Fan Shelf B. The thermal system employs a push-pull approach to move air through the system. The air flow enters from the bottom front and sides and exits from the top rear and sides.

Both fan trays are required for normal operations and are not redundant. However, individual fans, within a fan tray, are N +1 redundant with power hot-swap controllers. In the event of a single fan failure (within a fan tray), with the remaining fans running at full speed, the chassis will operate in normal room temperature, without one tray, for up to 60 minutes. A single fan failure within a fan tray will trigger an alarm for replacement of the fan tray.

A POWER LED and a FAULT LED are provided on each fan tray. The significance of an illuminated LED is described in Table 2-15 on page 2-22

There are two types of MCMs available for managing a TN780, the MCM-A and MCM-B. The parameter differences between the two modules are shown in Table 2-20 on page 2-25

Table 2-20 MCM-A and MCM-B differences

MCM-A Functional DescriptionThe MCM-A, is a half height module that slides into the chassis in slot 7A or slot 7B. The MCM-A is the shelf controller of all the modules resident within the DTC.The functions are:

Management gateway functions to the external DCN in the Main Chassis

Contains the software, and the database for the TN780

Note: In Release 1.2 the MCM-A can be deployed in a single-chassis system only.

Note: The MCM-A will be supported in non-redundant configurations only.

Note: The MCM-A and a MCM-B should not be located in the same chassis.For the procedure to upgrade from a MCM-A to a MCM-B refer to the UTStarcom TN780 Maintenance and Troubleshooting Guide.

MCM-B Functional DescriptionThe MCM-B, is a half height module that slides into the chassis in slot 7A or slot 7B. The MCM-B is the shelf controller of all the modules resident within the DTC.The functions are:

In a multi-chassis configuration, the MCM-B in the Main Chassis controls all the chassis within the TN780 network element

The MCM-B in the Expansion chassis performs shelf controller functions controlling only the mod-ules resident within that chassis

Management gateway functions to the external DCN in the Main Chassis

Contains the software, and the database for the TN780

The MCM-Bs in the Main Chassis and Expansion Chassis are interconnected through NCT ports located on the I/O Panel.

The MCM-B supports the local craft interfaces for local management access.

For high-availability, redundant MCM-Bs can be deployed in each DTC. One MCM-B actively performs the node/shelf control functions while the other MCM-B is in the standby mode. In a multi-chassis configuration, the interconnected redundant MCM-Bs provide the inter-chassis redundancy.

Note: In a Multi-Chassis configuration the DCN ports on the Main Chassis are active. The DCN ports on the Expansion Chassis are disabled.

Fan TrayThe OTC contains two removable fan trays, one on the left and one on the right of the chassis. Each fan tray consists of an individually controlled fan. The thermal system employs a push-pull approach to move air through the system, with air flow entering from the front of the chassis near the right side and exiting from the rear of the chassis near the left side (or from the front and rear for ETSI). The fan on the left side of the chassis is referred to as Fan Tray A, and the fan on the right side is referred to as Fan Tray B, when looking at the front of the OTC.

a. When there is no power fault condition, the Normally Open contact is closed and the Normally Close contact is open. When both PEM-A and PEM-B have power fault condition, the Normally Open contact is open and Normally Close con-tact is closed. The power fault is defined as when the power input into PEM-A or PEM-B is out of working range.





An alarm is raised when one of the fan fails. A failure requires replacement of the corresponding fan tray. The chassis will operate at below 40°C with a single fan tray.

Fan Tray LEDsThe fan trays have two status LEDs: POWER and FAULT LED are provided on each fan tray. The significance of a lit LED is described in Table 3-13 on page 3-18.

Technical SpecificationsTable 3-14 on page 3-18 gives the mechanical, electrical, environmental specifications and reliability data for the fan tray.

Air FilterA replacable air filter is necessary to filter out dust particles at the air intake of the OTC. Air is filtered at 80% dust arrestance. Depending upon the operational environment, the air filters have to be replaced at regular intervals, preferably once every 3 months.
