GPRSDevices sensitive to static

23 Jan 200312


68P02903W24-A

Devices sensitive to static

Introduction

Certain metal oxide semiconductor (MOS) devices embody in their design a thinlayer of insulation that is susceptible to damage from electrostatic charge. Sucha charge applied to the leads of the device could cause irreparable damage.

These charges can be built up on nylon overalls, by friction, by pushing thehands into high insulation packing material or by use of unearthed solderingirons.

MOS devices are normally despatched from the manufacturers with the leadsshorted together, for example, by metal foil eyelets, wire strapping, or byinserting the leads into conductive plastic foam. Provided the leads are shortedit is safe to handle the device.

Special handling techniques

In the event of one of these devices having to be replaced, observe thefollowing precautions when handling the replacement:

S Always wear an earth strap which must be connected to the electrostaticpoint (ESP) on the equipment.

S Leave the short circuit on the leads until the last moment. It may benecessary to replace the conductive foam by a piece of wire to enable thedevice to be fitted.

S Do not wear outer clothing made of nylon or similar man made material. Acotton overall is preferable.

S If possible work on an earthed metal surface or anti-static mat. Wipeinsulated plastic work surfaces with an anti-static cloth before starting theoperation.

S All metal tools should be used and when not in use they should be placedon an earthed surface.

S Take care when removing components connected to electrostatic sensitivedevices. These components may be providing protection to the device.

When mounted onto printed circuit boards (PCBs), MOS devices are normallyless susceptible to electrostatic damage. However PCBs should be handled withcare, preferably by their edges and not by their tracks and pins, they should betransferred directly from their packing to the equipment (or the other wayaround) and never left exposed on the workbench.

Swing frame

The purpose of the swing frame is to allow access to the rear of the PCU whenrear access to the cabinet is not available.

WARNING The swing frame cabinet must be bolted to the floor orsupported by a wall bracket at the top.Operation of a populated swing frame in an unsecuredcabinet presents a danger of toppling.Only one swing frame is to be open at any given time, thespare swing frame keys should be removed from theequipment and stored in a secure location.

Operation

NOTE All swing frame transit bolts must be removed prior tooperating the swing frame for the first time.

To open a swing frame:

1. Insert the swing frame key into the swing frame lock.

2. Turn key a quarter turn clockwise to unlock.

NOTE Only one key is used with each cabinet and is captive inthe swing frame lock when unlocked. This is to ensureonly one frame at a time can be open. The key must beremoved from the lock before the cabinet door can beclosed.

3. Slide the PCU fully out by pulling on the slam plate, located at the bottomof the cage frame, and withdrawing it from the cabinet until the rear of theframe firmly locks into position.

NOTE The entire PCU must be withdrawn from the cabinet forthe rear of the frame to lock into position.

4. Swing the PCU away from the cabinet by releasing the securing latchlocated on the left hand side of the frame (see Figure 3-5).

5. Hold the swing frame in the open position using the swing frame retainingbar, which can be set to 65_ or 90_ for required access.

To close the swing frame:

1. Release the swing frame retaining bar and carefully swing the PCU backto the closed position, ensuring it is held in place with the securing latch(see Figure 3-5).

CAUTION Ensure all cables are in the correct position and are not indanger of being caught or crushed, from the actions ofreplacing the swing frame back into the cabinet.

2. Firmly push the slam plate inwards, until it is almost flush with the frame,to release the catches which are holding the rear of the frame in its fullyout position.

Installing the PCU cabinet

Introduction to cabinet installation

WARNING If the cabinet is not stabilized there is a danger that it maytopple, particularly with a swing frame cabinet when theswing frames are rotated.The swing frame cabinet must be stabilized by bolting tothe floor, (or by fitting the supporting brackets to the top ofthe cabinet).

The cabinet can be mounted on a smooth concrete floor, or other strongsupportive cavity construction.

The swing frame cabinet requires three M10 floor mounting anchor bolts, or ifthe floor is not suitable supporting brackets, supplied with the equipment, mustbe fitted.

The static frame cabinet requires four M10 floor mounting anchor bolts to bolt itto the floor. Motorola recommend the static frame cabinet is secured to the floor.

The following cabinet option installations are described:

S PCU swing frame cabinet.

S PCU static frame cabinet.

Recommended bolt length for anchoring cabinets

The bolts and washers are locally sourced, with the length and type of the M10steel anchor bolts used to anchor cabinets is dependant on the depth andconstruction of the mounting surface. This must be determined by a site survey,carried out by a structural engineer.

Connecting the digital interface cable loom to the PCU

Introduction to digital loom connection

In addition to the connection procedure this section contains a brief overview ofthe digital interface and detailed cable routeing information to assist in theconnection procedure.

NOTE Ensure, prior to connection, the correct digital interfacecable loom has been selected:S For a PCU running software implementing coding

schemes 1 and 2, a cable loom containing 18 RJ-45to RJ-45 cables can be used.

S For a PCU running software implementing codingschemes 1, 2, 3 and 4, a cable loom containing 24RJ-45 to RJ-45 cables is required.

The digital interface cable connects three types of digital signal to the PCU:

S The GPRS data stream (LAPD protocol), GPRS signalling link (GSL), tothe BSC.

S The GPRS data stream (TRAU protocol), GDS (TRAU), to the BSC.

S The Gb link to the SGSN.

The GSL, the GDS (TRAU) and the Gb interface connect through the nonsystem slot E1 transition modules to network interface boards (NIBs), installedprior to shipment, on the PCU non-system-slot processor (DPROC) cards.

GSL

E1 cables from the BSC, carrying GSL are connected through transition moduleports to one of the two NIBs (PCI mezzanine cards�PMCs), mounted on a PICPconfigured DPROC.

GDS (TRAU)

An E1 cable from the BSC, carrying GDS (TRAU), can be connected to:

S A NIB mounted on a PICP configured DPROC, or

S A NIB mounted on a PRP configured DPROC.

GPRSConnecting the digital interface cable loom to the PCU

23 Jan 20033�36


68P02903W24-A

Gb

The Gb links are connected through transition module ports to:

S The other NIB mounted on the same PICP-configured DPROC as theGSL, or

S To either NIB on a separate PICP DPROC.

Each Gb link can carry 30 timeslots.

NOTE The connection for GSL E1 links to the BSC for softwaredownload is:S Default, PCU slot one (rear), PMC socket one,

Transition module port 1A (link 0) time slot 1.

S Secondary option (for PCU running software preGSR6), PCU slot two (rear), PMC socket one,Transition module port 1A (link 0) time slot 1.

S Secondary option (for PCU running software GSR6or later), PCU slot eleven (rear), PMC socket one,transition module port 1A (link 0), timeslot 1.

A NIB with Gb links cannot interface GDS or GSL.Only GDS (TRAU) can be connected to the PRP and onlyone GDS E1 link can be made to a NIB card.

The detailed connection information for the digital interface cable loom can befound in Table 3-7 and Table 3-8 in this section.

The routing for the digital interface cable loom is dependent on the cabinet type.

Initial configuration process

The PCU initial configuration process starts automatically when the PCU isswitched on.

1. The PCU boots up using PPCBug software, installed on the MPROC.

2. To begin Initialization, the BSC IP instructs the BSC Exec DISP to bring upthe GSL as specified in the database. On the PCU at the PCU systemprocessor (PSP) an IP (pIP) and Exec DLSP bring up the other side of thedefault GSL.

3. Once communication is established, the BSC IP queries the pIP for the setof code objects currently residing at the PCU, to determine which newobjects require sending. The required set are transferred from the BSC tothe PCU. The database is included in this transfer.

CAUTION The code download from the BSC can take up to 40minutes. When the CPU and PCI LEDs are flashing amberthe PCU is writing to the flash ROM. Do not switch offPCU during code download or corruption of the 96 Mbyteflash ROM can occur.

4. The PSP, once the download is complete, determines which card is ineach slot of the PCU and downloads the appropriate objects anddatabase information to each DPROC and NIB. The database is stored innon-volatile memory at the PSP.

5. The PSP distributes the configured number of cells in the database acrossthe PRPs. It also creates router tables of cell to router and distributesthese tables to all boards to allow communications.

6. The gateway manager (GWM) initiates process start-up at the PRPs andPICPs

7. The GBL interface is initialized as the GSL is brought into service. ThePSP indicates to the BSC CA that the PCU is enabled and registers forcalls.
