u
Do not expose the SIMMs to moisture or extreme temperatures.
u
Do not remove the SIMMs from the antistatic bag until instructed.
Follow these SIMM population rules to correctly install the SIMMs.
u
Each bank has two slots. Fill both slots in a bank.
u
Use the same size SIMM in both slots in a bank.
u
Install SIMMs one bank at a time, beginning with bank 0 and ending with bank 3.
u
After adding or replacing SIMMs, restart the computer. The new memory configuration
is detected automatically.
To install a memory upgrade:
1. Remove any option boards that interfere with access to the SIMM sockets.
2. Remove the existing SIMMs from their sockets before adding new ones. Refer to the
following figure.

7. Repeat steps 5 through 7 for each SIMM.
8. Replace the option boards that you removed in step 1 above.
9. After you close the base unit, restart the system. The new memory is recognized
automatically.
Adding Internal SCSI Devices
Desktop systems are equipped with an Ultra SCSI controller for all SCSI devices.
u
You can install internal Ultra SCSI devices, or devices controlled from an expansion
card, in the device bays located on the right front side of the base unit of a desktop
system. The device must be 1.6 inches high or less to fit in these bays.
manuals search engine
37
u
You can install a replacement or a second SCSI hard disk drive into the system hard
disk drive bracket between the riser card and power supply. If the hard disk drive is
more than 1 inch high, you will not be able to install a second hard disk drive into the
system hard disk drive bracket, nor will you be able to use ISA slot 1. If you install a
second hard disk drive in the system hard disk drive bracket, you will not be able to use
ISA slot 1. If you install a non-Ultra SCSI device, data transfer rates are limited to the
device’s speed.
Deskside systems are equipped with an Ultra Wide SCSI controller for internal SCSI
devices. The internal device bays are located above the floppy disk drive bay. You can
install internal Ultra Wide SCSI devices, or devices controlled from an expansion card, in
the device bays. The device bays are designed to accommodate 1.6-inch high devices; if a
device is more than one 1.6-inch high, the bay underneath must be left empty. If you install
a non-Ultra Wide SCSI device, data transfer rates are limited to the device’s speed.
CAUTION
Connecting a non-compliant SCSI-1 device to a TD-x20, TD-x25, TDZ-x20, or TDZ-x25
workstation may cause your system to stop working, or lead to other unpredictable results.
To install an internal SCSI device:
NOTE
Refer to Chapter 2, “Maintaining System Devices,” for information about removing and
replacing devices in the system, and for information on installing a device in the optional
device bay on the desktop system.
1. If a device already occupies the location in which you are adding the new device, remove
the existing device. If installing the device into an empty drive bay, remove the support
or slide bracket from the drive bay.
2. Mount the device to the support or slide bracket, if necessary.
3. If you are installing the device into one of the forward device bays in a desktop system,
slide the device through the faceplate and secure it to the chassis.
4. If installing hard disk drives into the system hard disk drive bracket in a desktop system,
replace the bracket, ensuring the bracket tabs engage the slots on the peripheral brace.
NOTE
ISA Slot 1 can be used only if a single system hard disk drive is installed, and if it is less than
1.6-inches in height.
5. Connect the SCSI cable and power cable to the device. The SCSI cable is keyed to
ensure proper insertion, so that the red stripe (pin 1) is adjacent to the power connector.

6. After closing the base unit, install the device drivers and configure the device according
to the vendor’s instructions, if necessary.
Adding External SCSI Devices
Desktop systems are equipped with an Ultra SCSI controller for all SCSI devices. If you
install a non-Ultra SCSI device, data transfer rates are limited to the device’s speed.
Deskside systems are equipped with a separate Ultra SCSI controller for external SCSI
devices. If you install a non-Ultra SCSI device, data transfer rates are limited to the device’s
speed.
CAUTION
Connecting a non-compliant SCSI-1 device to a TD-x20, TD-x25, TDZ-x20, or TDZ-x25
system may cause your system to stop working, or lead to other unpredictable results.
You can add up to five external single-ended SCSI devices to a desktop workstation, and up
to seven external single-ended SCSI devices to a deskside workstation. The total length of
the external SCSI cables depends on the number of devices connected to the SCSI adapter.
manuals search engine
39
The total length must not exceed the following:
Devices
SCSI-1
SCSI-2
Ultra SCSI
1 to 4
6 meters
3 meters
3 meters
5 to 8
3 meters
3 meters
1.5 meters
NOTE
You must count the controller as one device.
When calculating the total length of the SCSI cables connected to the SCSI adapter, use the
following estimates where appropriate:
SCSI cabling inside a desktop workstation
101.6 mm
SCSI cabling inside each external device
203.2 mm
NOTE
The last external device on the SCSI cable chain must supply active termination. All other
external devices must have SCSI termination disabled or removed.
To install an external SCSI device:
1. Set the device’s SCSI ID to an unused number and enable or disable the device’s SCSI
termination according to the note above and the vendor’s instructions.
2. Connect one end of the SCSI cable to the SCSI port on the back of the base unit. If
other external devices are installed, connect the SCSI cable to the available SCSI port on
the last device on the SCSI cable chain.
3. Connect the new SCSI device to the other end of the SCSI cable.
4. If necessary, install the device drivers and configure the device according to the vendor’s
instructions.

PCI to ISA Bus Interrupt Mapping
The ISA bridge (Intel 82371SB) provides the sixteen conventional ISA interrupts, plus four
interrupt request pins for PCI peripheral interrupts (PIRQ0 through PIRQ3). For PC-AT
architecture compatibility reasons, the PCI interrupts are routed to the ISA interrupts within
the ISA bridge. The assertion of a PCI interrupt concludes in an ISA interrupt being
asserted.
Bit 7 of each PIRQ registers enable (Low) or disable (High) the routing of the PIRQ to an
ISA interrupt. The lowest four bits (3:0) of each PIRQ register determines to which ISA
interrupt the PIRQ will be routed. The PIRQs can be mapped to the following ISA
interrupts:
IRQ 5, 9, 10, 11, 15

Each PCI slot on the riser card has four available interrupt lines: INTA, INTB, INTC, and
INTD. These are connected to the PCI interrupts, PIRQ0 through PIRQ3, as shown below:

The spare interrupts listed above may be assigned to PCI and ISA devices. When you add a
PCI device to the system, the interrupt will be automatically assigned by the system BIOS.
However, at least one interrupt must be available for the PCI bus. For increased
performance, one interrupt should be left available for each PCI based controller used in the
system. When you add a ISA board, you must assign the interrupt using the System BIOS
and jumpers on the option board.
The Sound Controller can be configured for either IRQs 5, 7, 9, 11, 12, or 15. The MIDI
Port can be configured for either IRQs 9, 10, 11, 15, or no interrupt, in which case it will act
as a write-only device.
