Installing New Hardware Components Note: Always observe anti-static precautions when handling electronic equipment. ↓ Installing new DSP or I/O cards ↓ Installing new I/O modules INTRODUCTION TO THE HURON New Huron cards and modules can be purchased to expand the capability of Huron. Qualified service personnel should perform the installation of these cards or modules. These guidelines should be followed when installing new cards: Addition and removal of all cards should only be attempted when the power to the Huron system is off. When installing a Huron ADAT I/O card, this should be installed in slot 0 (the leftmost slot when viewing the Huron from the front). When installing a new DSP or I/O carrier card, install it in the slot directly next to the last Huron DSP or I/O card. There should be no vacant slots between Huron DSP and I/O cards. Addition and removal of all modules should only be attempted when the power to the Huron system is off. When installing new I/O modules onto a Huron I/O carrier card, the position and orientation of the modules is very important. Input modules are always populated in module 8 first, followed by module 7, and so on. Output modules are always populated in module 1 first, followed by module 2, and so on. When inserting a new input module insert it in the highest available slot number. When inserting a new output module, insert it in the lowest available slot number. Always be careful to ensure the correct orientation of any modules. The orientation shown in Figure 4 must be adhered to for all modules. Special attention must also be paid to ensuring the module connector pins mate perfectly with the I/O base card connectors. Incorrect insertion of the modules could result in damage to the module and/or the workstation. HURON TECHNICAL MANUAL PAGE 30

Installing AT Add-In Cards If the Huron System does not work after the installation of an ISA card. ↓ Check the following settings Figure 4 — Correct orientation of I/O module during installation INTRODUCTION TO THE HURON The Huron system is an AT compatible computing system. Standard ISA and PCI cards can be added to the system and configured for correct operation. The installation manuals for any add-in cards should be followed carefully to ensure their correct operation in the system. If the Huron system does not work after adding an AT compatible card to the system you should check the configuration of Huron and the add-in card. The most common problem is a conflict between an I/O ROM of an ISA add-in card and the address space used by the Huron system. • The Huron system has a floppy controller built in to the single board computer. Some SCSI cards have a floppy disk drive controller included. This additional SCSI drive controller should be disabled. • Check the base address of any RAM or I/O ROM on the AT add-in card. Some typical default base addresses for add in cards are 0xC800 for ethernet cards and 0xDC00 for SCSI cards. If you determine that the base addresses for the Huron system and the new add-in card overlap, then you must change one of the base addresses. Either follow the instructions in the installation manual of the new add-in card or change the Huron base address as explained below. HURON TECHNICAL MANUAL PAGE 31

INTRODUCTION TO THE HURON<br />

The <strong>Huron</strong> system is an AT compatible computing system.<br />

Standard ISA and PCI cards can be added to the system and<br />

configured for correct operation. The installation manuals for<br />

any add-in cards should be followed carefully to ensure their<br />

correct operation in the system.<br />

If the <strong>Huron</strong> system does not work after adding an AT<br />

compatible card to the system you should check the<br />

configuration of <strong>Huron</strong> and the add-in card. The most common<br />

problem is a conflict between an I/O ROM of an ISA add-in<br />

card and the address space used by the <strong>Huron</strong> system.<br />

• The <strong>Huron</strong> system has a floppy controller built in to the<br />

single board computer. Some SCSI cards have a floppy disk<br />

drive controller included. This additional SCSI drive<br />

controller should be disabled.<br />

• Check the base address of any RAM or I/O ROM on the AT<br />

add-in card. Some typical default base addresses for add in<br />

cards are 0xC800 for ethernet cards and 0xDC00 for SCSI<br />

cards.<br />

If you determine that the base addresses for the <strong>Huron</strong> system<br />

and the new add-in card overlap, then you must change one of<br />

the base addresses. Either follow the instructions in the<br />

installation manual of the new add-in card or change the <strong>Huron</strong><br />

base address as explained below.<br />
