3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 1.3.1 The PCI Interface 4.333 pc PCI, a high-speed standard local bus, interfaces I/O components to the processor and memory subsystems in equipment ranging from PCs to servers. The PCI functionality for the SYM8953U is contained within the Symbios SYM53C895A PCI to Ultra2 Controller with LVD Link Universal Transceivers.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 1.3.3 Ultra2 SCSI Technology The SYM8953U fully supports Ultra2 SCSI. Ultra2 SCSI is an extension of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of standards. SCSI2 expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers. For the internal bus, special impedance SCSI ribbon cables are specified for operation with Ultra and Ultra2 SCSI devices.

Ultra2 SCSI with LVD allows a longer SCSI cable and more devices on the bus, using the same cables defined in the SCSI-3 parallel Interface (SPI-2) standard for Ultra SCSI. Important: 4.333 pc To utilize Ultra2 SCSI performance, you must only have LVD devices on the bus.

The use of a static ground strap is recommended. 4.333 pc Step 5. Locate the slots for installing a PCI plug-in board. The SYM8953U requires a PCI slot that allows bus master operation. See Figure 2.2. Step 6. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc Remember: The SCSI bus requires proper termination, and no duplicate SCSI IDs. 4.333 pc 2.2 Detailed Installation Procedure This section provides step-by-step instructions for installing the SYM8953U host adapter board, and connecting it to your SCSI peripherals. If you are experienced in these tasks, you may prefer to use Section 2.1, “Quick Installation Procedure.” 2.2.

3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc If you have more than one internal device to connect, use an internal SCSI ribbon cable with the required number of connectors attached along its length and proceed to the next step. If you have only one internal device, proceed to page 2-14. 4.333 pc Step 3. Plug the cable into each additional device as needed. An example of this type of chained connection is shown in Figure 2.7. Make sure to match pin 1 on all connections. Figure 2.

To connect external SCSI devices to the SYM8953U host adapter: Step 1. Plug the 68-pin HD connector on one end of a shielded external SCSI cable (see Figure 2.3) into the host adapter connector J3 (see Figure 2.1). This connector is in the bracket attached to the back panel of your computer. Figure 2.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc Step 2. Plug the 68-pin connector on the other end of the shielded external SCSI cable into the SCSI connector on your external SCSI device. An example of this connection is shown in Figure 2.10. 4.333 pc Figure 2.10 External SCSI Device Cable 44.25 pc HD Connectors If this is the only external SCSI device on your system, proceed to Section 2.2.6, “SCSI Bus Termination,” page 2-18 for termination instructions.

The first and last physical SCSI devices connected on the ends of the SCSI bus must have their terminators active. All other SCSI devices on the bus must have their terminators removed or disabled.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 2.2.6.1 4.333 pc Internal Bus Connections If you have only internal SCSI device connections to your host adapter, you must terminate the last internal device on the SCSI bus. You must disable the terminators on all other devices. Termination on your host adapter is automatically enabled in this case. Figure 2.12 shows an example of how termination is determined for this SCSI bus configuration. Figure 2.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 2.2.6.2 External Bus Connections If you have only external SCSI device connections to your host adapter, you must terminate the last external device on the SCSI bus. You must disable the terminators on all other devices. Termination on the host adapter is automatically enabled in this case. Figure 2.13 shows an example of how termination is determined for this SCSI bus configuration. Figure 2.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 2.2.6.3 Internal and External Bus Connections If you have both internal and external SCSI device connections to your host adapter, you must terminate the last internal and last external devices on the SCSI bus. You must also disable the termination on all other devices. Termination on the host adapter is automatically disabled in this case. Figure 2.14 shows an example of how termination is determined for this SCSI bus configuration. Figure 2.
3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 2.2.7 Setting SCSI IDs You must set each SCSI device and the host adapter to a separate SCSI ID 0 through 15. SCSI ID 7 is the preset host adapter setting, giving it the highest priority on the SCSI bus. If you plan to boot your computer from a SCSI hard disk drive on the SCSI bus, that drive should have the lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for system performance optimization, an ID other than 0 (zero) can be used.
