1.1 Hardware Platform
1.1.1 Introduction of ATCAWith the development of data services represented by the 3G communication service,the network devices and the computing devices are experiencing a rapid growth in termof the computing performance. The telecommunication operators have become moreconcerned about the openness and compatibility of the telecommunication products andtelecommunication platforms. Advanced Telecommunications Computing Architecture(ATCA), which is developed by PCI Industrial Computer Manufacturers Group (PICMG),has become a universal, reliable, and open hardware architecture platform. It is expandingfrom the radio access equipment market to the market requiring higher reliability such asIMS.
It enjoys the following features:
l Powerful computing capabilityl High reliability of telecommunication levelsl Large throughputl easy expansion of servicesl Strong manageability and interworkingl High level of openness and standardizationl Convenient operation and maintenancel Separate control stream and service stream
1.1.2 Introduction of ETCAEnhanced ATCA (ETCA) is developed on the basis of ATCA. It adds the access capabilityto ATCA.
ZTE ZXUR 9000 GSM system, which is based on the ETCA hardware platform, possessesa comprehensive system competitive power.
The ETCA hardware platform enjoys the following features:

SJ-20101019110320-003|2012-02-09(R1.1) ZTE Proprietary and Confidential
ZXUR 9000 GSM Hardware Description
l Compatible with the ATCA platform
à Fewer types of physical boards are required because standard ATCA bladeboards are used as the front boards. The front boards process the services.
à Enhanced rear boards provide higher interface performance. All the interfacesare provided on the rear boards. The front boards no longer provide externalinterfaces.
à The minimum configuration is a single shelf configuration that can satisfy therequirements of most applications.
l Convenient maintenance
à Software versions can be downloaded online.
à Information of the rack, shelves, and slots can be stored in an independentmemory board, and maintenance is available through either software orhardware.
à The lower layer information of boards of each node is managed by anindependent shelf management module CMM.
l High reliability
à The system switch is implemented through a dual-star architecture, whichprovides the all-redundancy capability.
à All components support the backup function.
à Both inter-shelf connection ports and intra-shelf connection ports supportTRUNK.
1.1.3 Hardware FeaturesThe hardware system ZXUR 9000 GSM is based on the ETCA hardware platform,providing the following features:
l Provides a new ETCA platform after making partial improvement on the basis of ATCAstandard.
l Provides various external interfaces, satisfying the all-IP requirement and beingcompatible with traditional network (such as E1 and STM-1) access.
l Adopts the structure of control stream and service stream being completely separated.l Supports 1+1 backup for the interface boards, supports load sharing for the switching
boards, supports 1+1 backup for the control-plane processing boards, and supportsload sharing for the user-plane processing boards.
l Standardizes internal interfaces and reduces the association between the lower layerand the applications.
l Supports the evolution towards IPv6.l Protects the operators' investment by supporting the future development of networks,
the multi-mode wireless system applications, and evolution towards LTE and HSPA+.l Provides a green system solution by reducing the number and types of boards and
shelves. Limits the maximum configuration into a single rack.

3.1 Subrack TypesA subrack combines various boards and units into an independent functional unit. Thesubrack provides a good running environment for all units.
The ZXUR 9000 GSM subracks fall into the following types:l Power distribution subrackl Ventilation subrackl ETCA subrack
3.2 Power Distribution Subrack
3.2.1 Power Distribution Subrack FunctionsThe power distribution subrack is also called Power Distribution Unit (PDU). It is installedat the cabinet top, providing power supply for the entire cabinet.
PDU implements functions including power distribution, short-circuit protection, lightningprotection, and power supply and environment monitoring.
l Power distribution: Both input and out of PDU support dual redundancy. PDU providesa pair of three inputs and a pair of ten outputs.
l Short-circuit protection: Each output is equipped with a circuit breaker for outputcontrol and short-circuit protection.
l Lightning protection: The lightning protection module inside PDU provides a rack-levellightning protection. It works with the lightning protection units of rack and boards toform a multi-level lightning protection system.
l Power supply and environment monitoring: The monitoring involves the voltage,circuit-breaker status, rack and equipment room access control, temperature,humidity, smoke, infrared, and lightning protection.

l Jumper position 7 is always not inserted with a jumper cap.l Jumper position 8 (check position) is the odd check, which ensures that the jumper
caps on ECDM are odd number of caps. If the number of jumper caps on the ECDMis an even number, the system will display that the jumper is incorrect.
Note:
One ETCA subrack is configured with two ECDMs. You should make sure that the jumperconfigurations at two sides are consistent, and the configured rack and shelf informationis the same.

Processes global procedure, controls the operation and maintenance of the entiresystem, and connects OMM through internal media plane. As the core of ZXUR 9000GSM operation and maintenance, UMP directly or indirectly monitors and managesthe boards in the system and manages the configuration of each board and othercomponents.
Note:
When UMP performs OMM function, it is inserted in slots 5 and 6 in the master shelf.Through the network port at EGBS, it is connected with the switch, which is then connectedwith EMS server and O&M module client.
When UMP performs OMP function, it is inserted in slots 7 and 8.

In this table:l The jumper is in ON state after inserted with jumper cap, which is represented as 0.
Otherwise, it is in OFF state, represented as 1. The DIP switch code on the left is lowbit and the DIP switch code on the right is high bit. For example, if jumpers 1, 2, and3 are inserted with jumper hats and other jumpers not, infer that the shelf is the thirdshelf in the eighth rack.
l The jumper cab of bit 7 is fixed as non-inserted.l Bit 8, that is, check bit, is polarity check bit. Therefore, bit 8 is used to ensure that
the total number of jumper caps on ECDM is an odd number. If the total number is aneven number, the system prompts jumper error.

Generally, the shelf has two ECDMs. Ensure that the jumper configurations on the twoECDMs are consistent and the configurations of rack and shelf are the same.
