Description

Installation Instructions
When the MVME147SB-1 has been configured as desired by the user, it can be installed in the system as follows:
1. Turn all equipment power OFF and disconnect power cable from AC power source.
2. Remove chassis cover as instructed in the equipment user’s manual.
3. Remove the filler panel(s) from the appropriate card slot(s) at the front and rear of the chassis (if the chassis has a rear card cage). If the MVME147SB-1 is configured as the system controller, it must be installed in the left most card slot (slot 1) to correctly initiate the bus grant daisy-chain. The MVME147SB-1 is to be installed in the front of the chassis and the MVME712A/MVME712AM/ MVME712B/MVME712M may be installed in the front or rear of the chassis. Every MVME147S is assigned an Ethernet station address. The address is $08003E2XXXXX where XXXXX is the unique number assigned to the module (every MVME147S has a different value for XXXXX). Each Ethernet station address is displayed on a label attached to the back of the MVME147S front panel. In addition, the XXXXX portion of the Ethernet station address is stored in BBRAM, location $FFFE0778 as $2XXXXX. If Motorola networking software is running on an MVME147S, it uses the 2XXXXX value from BBRAM to complete the Ethernet station address ($08003E2XXXXX). The user must assure that the value of 2XXXXX is maintained in BBRAM. If the value of 2XXXXX is lost in BBRAM, the user should use the number on the front panel label to restore it. Note that MVME147SBug includes the “LSAD” command for examining and updating the BBRAM XXXXX value. If nonMotorola networking software is running on an MVME147S, it must set up the 7990 so that the Ethernet station address is that shown on the front panel label to ensure that the module has a globally unique Ethernet station address.
4. Insert the MVME147SB-1 into the selected card slot. Be sure the module is seated properly into the connectors on the backplane. Fasten the module in the chassis with the screws provided. For proper operation, a 32-bit VMEbus backplane should be used. This insures that power is sufficiently distributed over enough power pins on connectors P1 and P2.
5. Remove IACK and BG jumpers from header on chassis backplane for the card slot in which the MVME147SB-1 is installed (if applicable).
6. Install MVME712A module according to installation instructions in the MVME712M Transition Module and MVME147SB-1 Adapter Board User’s Manual. 7. Turn equipment power ON.
The MVME147SB-1 provides +12 Vdc power to the Ethernet transceiver interface through a 1 amp fuse (F1) located on the MVME147S module. The fuse is socketed and located near P1. If the Ethernet transceiver fails to operate, check the fuse. When using the MVME147SB-1 module, the yellow LED (DS1) on the MVME147SB-1 front panel, lights when LAN power is available, indicating that the fuse is good. Note that the yellow LED may light if any one of the four serial ports is connected on the MVME147SB-1 regardless of the state of F1. The MVME147S provides SCSI terminator power through a 1 amp fuse (F1) located on the P2 adapter board. The fuse is socketed. If the fuse is blown, the SCSI devices may not operate or may function erratically. When the P2 adapter is used with an MVME147SB-1 and the SCSI bus is connected to the MVME147SB-1, the green LED (DS2) lights when there is SCSI terminator power. If the LED flickers during SCSI bus operations, the fuse should be checked.
