## Boards for ASB 150 02

This document describes all the ASB 150 02 boards from R3 upwards, which still might be installed at the customer site. Some of these boards are already phased out and can not be ordered anymore.To get a an overview of all the boards which are still in active sustaining, please refer to the document
ASB 150 02 spare parts list (154 11- ASB 150 02 Uen).

### Handling of PBAs

Service personnel shall always connect themselves to ground to prevent damage caused by static discharges.

Note

Boards with Electrostatic Sensitive Devices (ESD) are marked with a sign.In the interest of quality and reliability of the system boards, always handle static sensitive boards with special care. Always use a wrist strap connected to a low resistance ground e.g. provided on the cabinet:
Use portable equipment LYA 30101 as a protection against electrostatic discharges. For safety reasons the wrist strap should be equipped with a 1 MOhm series resistor.

Some of the benefits of ESD protection are:

- less failures/service calls
- lower maintenance costs
- higher customer satisfaction

### Connection fields on the PBAs

### Board position numbering

#### BP 250 (Cabinet: BDV 113 08)

Board position numbering for:

- Cabinet 0: position 0,1 --- 8.
- Cabinet 1: position 16,17 --- 24.
- Cabinet 2: position 48,49 --- 56.

#### BP 128i (Cabinet: BDVBS 101 06)

Board position numbering for:

- Cabinet 0: position 0,1,2,3,4.
- Cabinet 1: position 16,17,18,19,20.

#### BP 50 (Cabinet: BDVBS 101 05)

Board position numbering for:

- Basic unit: position 0,1 --- 4.

### Placing of boards

The cabinets BDV 113 08, BDVBS 101 05 and
BDVBS 101 06 are prepared for arbitrary furnishing of boards belonging to the ASB150 02 system but certain constraints should be considered for best performance results.

#### BDV 113 08

The cabinet 0 and the two optional cabinets 1 and 2 have to be equipped as follows:

Pos. 0 |  | Reserved for CPU-D_

Pos. 1-8, 16-24, 48-56 |  | Available for arbitrary PBA configuration like ELU-_,MFU, VMU-D, VMU-HD, AUX_, BTU-_ , REG, IC-CU_ and IC-LU. The latter one requires PUB 5 or higher.

Pos. 8, 24, 56 |  | Due to thermal considerations this position is recommended for the IPU. If any other position has to be chosen or in case of multiple IPUs then the next right hand board position of the IPU must be left free.

#### BDVBS 101 06

The cabinet 0 and the optional cabinet 1 have to be equipped as follows:

Pos. 0 |  | Reserved for CPU-D_

Pos. 1-4 ,16-20 Available for arbitrary PBA configuration like ELU-_,MFU, VMU-D, VMU-HD, AUX_, BTU-_ , REG, IC-CU_, IC-LU and IPU. |  |

Note

The cabinet BDVBS 101 06 does not support ELU-C boards

#### BDVBS 101 05

This single cabinet solution supports only five slots which has to be equipped as follows.

Pos. 0 |  | Reserved for CPU-D_

Pos. 1-4 |  | Available for arbitrary PBA configuration like ELU-_,MFU, VMU-D, VMU-HD, AUX_, BTU-_ , REG,IC-CU_ and IC-LU. The latter one requires PUB 50 R4A or higher.

Pos. 4 |  | Due to thermal considerations this position is recommended for the IPU. If any other position has to be chosen or in case of multiple IPUs then the next right hand board position of the IPU must be left free.

Note

The cabinet BDVBS 101 05 does not support ELU-C boards

Note

The backplane PUB 50 R3A or higher is required to support the IC-LU board

Install sub-equipped boards in the last position after the standard boards to enable easy upgrading without having to re-number trunks and extensions.

The Integrated Cordless system has be installed within one cabinet. BMS cannot detect IC-LU boards installed in the system so it is advisable to locate these boards to the right of the IC-CU_ board. IC-LU boards can be removed and replaced without needing to shut down the exchange. All boards except the CPU-D_ can be exchanged under power provided that the board is replaced by a board of the same type and configuration. New boards e.g. to upgrade the system, can be installed under power in a free slot of the cabinet.

When installing boards with ground brackets in a cabinet of an earlier release of BDV 113 08, which not prepared for them, take out the screws of the ground brackets at the top and bottom of the boards. Then bend the bracket at the top slightly away from the cabinet to allow a clearance for the front cover to slip on correctly.

#### EMC

The ferrites, with the ERICSSON ordering number STF 82 601, should be situated close to the slot where the cables are led out of the cabinet. Two turns through the ferrite core are sufficient to comply with EN 55022 Class B and to avoid disturbances in non-industrial, residential (home) usage.
