All memory and I/O components are located on a single system board that contains a memory subsystem, PCI bus, ISA bus, integrated SCSI fast/wide/Ultra I/O controllers, and option slots for PCI-based and ISA-based option modules.
Processor Module
The system supports up to two processor modules that can be installed on the system board. Each processor module contains a 21264 microprocessor. The 21264 microprocessor is a superscalar chip with out-of-order execution and speculative execution to maximize speed and performance. It contains four integer execution units and dedicated execution units for floating-point add, multiply, and divide. The chip also has an integrated instruction cache and a data cache. Each cache consists of a 64 KB two-way set associative, virtually addressed cache divided into 64-byte blocks. The data cache is a physically tagged, write-back cache.
The EV6 (500 MHz) processor module contains 4 MB secondary B-cache (backup cache) consisting of late-write synchronous DRAMs (dynamic random access memory) that provide low latency and high bandwidth. The EV67 (667 MHz) processor module has an 8 MB DDR (dual data rate). See the documentation that accompanies a processor upgrade for instructions on installing additional processors.
Memory
The system supports up to four banks of memory on the system board. Each bank contains four slots for a total of 16 slots. The system uses 200-pin buffered synchronous dual in-line memory module (DIMMs). See Chapter 5 for instructions on installing DIMMs.

N+1 Fan Configuration
The SFM supports and monitors the two system fans. For optimal cooling, both fans are always running. If one of the fans fails or is hot-swapped for servicing, the system continues to function with the other fan running at full speed.
The fan thermostat is set to drive the fans at their minimum speed in environments below 26ºC to keep noise levels low. As system temperature rises, the fan speed increases to increase cooling. If the system temperature rises above 55ºC (due to high system loads or high ambient temperature), the system software receives an I/O interrupt and the system shuts down within 30 seconds.
Cover Interlock
The SFM has a side cover interlock connector that prevents the system from operating with the system cover open. System power cannot be turned on until the cover is closed. If the cover is opened while the system is running, power shuts off immediately.

1.8 Power Supplies
The system comes with two 375-watt power supplies that are connected in parallel. A third power supply can be added for redundancy. Power supply 0 (PS0) is the leftmost supply in a pedestal system and the topmost supply in a rackmount system.
Figure 1–8 Power Supplies (Pedestal Orientation)
NOTE: On a system with two power supplies, a power supply blank is installed
to maintain the proper airflow.

CAT0043
Page 33
A power backplane integrates the supplies for power distribution, monitoring, and control. The power supplies can be accessed and removed through the front of the enclosure. See Chapter 5 for instructions on adding or replacing a power supply.
The following voltages are provided: +3.3, +5.0, +12.0, –12.0, +5.0 Aux (+5.0 Aux always powered). Two internal fans cool the power supply. The fans are temperature controlled and speed up as the power supply temperature increases.
N+1 Power Supply Configuration
Two power supplies must be installed and working for the system to operate. The system shuts down if the number of working power supplies ever falls below two. In a three-power-supply configuration, a power supply may be removed for servicing without interrupting system operation. An I/O interrupt is generated whenever the number of power supplies in operation changes.

1.10 Hard Disk Drive Storage
The system comes with either a four-slot storage subsystem that holds
1.6-inch drives or a six-slot storage subsystem that holds 1.0-inch drives. Figure 1–10 shows the storage subsystems.
Figure 1–10 Four-Slot and Six-Slot Storage Subsystems
The storage system backplane contains on-board multimode terminators that provide LVD (low voltage differential) termination to the bus when all devices are LVD. If an SE (single-ended) device is installed in the backplane, the terminators automatically switch to SE mode termination. All devices on the bus will operate in SE mode and all transactions will be subject to SE speed and length limitations.

from a RIS server.
You can set a default boot device, boot flags, and network boot protocols for Tru64 UNIX or OpenVMS using the SRM set command with environment variables. Once these environment variables are set, the boot command defaults to the stored values. You can override the stored values for the current boot session by entering parameters on the boot command line.
The SRM boot-related environment variables are listed below and described in the following sections.
auto_action Determines the default action the system takes when the
system is power cycled, reset, or experiences a failure.
bootdef_dev
boot_file
boot_osflags
ei*0_inet_init or ew*0_inet_init
ei*0_protocols or ew*0_protocols
Device or device list from which booting is to be attempted when no path is specified on the command line.
Specifies a default file name to be used for booting when no file name is specified by the boot command.
Defines parameters (boot flags) used by the operating system to determine some aspects of a system bootstrap.
Determines whether the interface’s internal Internet database is initialized from nvram or from a network server (through the bootp protocol). Set this environment
ariable if you are booting Tru64 UNI
Defines a default network boot protocol (bootp or mop).
4-2 DS20E Reference Guide

4.1.1 auto_action
The auto_action environment variable specifies the action the console takes any time the system powers up, fails, or resets. The value of auto_action takes effect only after you reset the system by pressing the Reset button or by issuing the init command.
The default setting for auto_action is halt. With this setting, the system stops in the SRM console after being initialized. To cause the operating system to boot automatically after initialization, set the auto_action environment variable to boot or restart.
When auto_action is set to boot, the system boots from the default boot
device specified by the value of the bootdef_dev environment variable.
When auto_action is set to restart, the system boots from whatever device
it booted from before the shutdown/reset or failure.
NOTE: After you set the auto_action environment variable, it is recommended
that you set the boot device and operating system flags as well, using the set bootdef_dev and set boot_osflags commands.
The syntax is:
set auto_action value
The options for value are:
halt
The system remains in console mode after power-up or a system crash.
boot The operating system boots automatically after the SRM init
command is issued or the Reset button is pressed.
restart
The operating system boots automatically after the SRM init command is issued or the Reset button is pressed, and it also reboots after an operating system crash.
Booting and Installing an Operating System 4-3

Examples
In the following example, the operator sets the auto_action environment variable to restart. The device specified with the bootdef_dev environment variable is dka0. When Tru64 UNIX is shut down and rebooted, the system will reboot from dka0.
P00>>> show auto_action auto_action halt P00>>> set auto_action restart P00>>> init . . . P00>>> show auto_action auto_action restart P00>>> show bootdef_dev bootdef_dev dka0 P00>>> boot ... [Log in to UNIX and shutdown/reboot]
#shutdown -r now ... console will boot from dka0
In the following example, auto_action is set to restart, but Tru64 UNIX is booted from a device other than the device set with bootdef_dev. When Tru64 UNIX is shut down and rebooted, the system reboots from the specified device.
P00>>> boot dka100 . . . [Log in to UNIX and shutdown/reboot] #shutdown -r now ... console will boot from dka100

4.1.2 bootdef_dev
The bootdef_dev environment variable specifies one or more devices from which to boot the operating system. When more than one device is specified, the system searches in the order listed and boots from the first device with operating system software.
Enter the show bootdef_dev command to display the current default boot device. Enter the show device command for a list of all devices in the system.
The syntax is:
set bootdef_dev boot_device
boot_device
The name of the device on which the system software has been loaded. To specify more than one device, separate the names with commas.
Example
In this example, two boot devices are specified. The system will try booting from dkb0 and if unsuccessful, will boot from dka0.
P00>>> set bootdef_dev dkb0, dka0
NOTE: When you set the bootdef_dev environment variable, it is
recommended that you set the operating system boot parameters as well, using the set boot_osflags command.

4.1.3 boot_file
The boot_file environment variable specifies the default file name to be used for booting when no file name is specified by the boot command. The factory default value is null.
The syntax is:
set boot_file filename
Example
In this example, the system is set to boot from dka0.
P00>>> set boot_file dka0
4-6 DS20E Reference Guide
Page 85
4.1.4 boot_osflags
The boot_osflags environment variable sets the default boot flags and, for OpenVMS, a root number.
Boot flags contain information used by the operating system to determine some aspects of a system bootstrap. Under normal circumstances, you can use the default boot flag settings.
To change the boot flags for the current boot only, use the flags_value argument with the boot command.
The syntax is:
set boot_osflags flags_value
The flags_value argument is specific to the operating system.
Tru64 UNIX Systems
Tru64 UNIX systems take a single ASCII character as the flags_value argument.
Load operating system software from the specified boot device
a
(autoboot). Boot to multiuser mode.
Prompt for the name of a file to load and other options (boot
i
interactively). Boot to single-user mode.
Stop in single-user mode. Boots /vmunix to single-user mode and stops
s
at the # (root) prompt.
D Full dump; implies “s” as well. By default, if Tru64 UNIX crashes, it
completes a partial memory dump. Specifying “D” forces a full dump at system crash.
Example
The following setting will autoboot Tru64 UNIX to multiuser mode when you enter the boot command.
P00>>> set boot_osflags a
Booting and Installing an Operating System 4-7
Page 86
Linux Systems
The flags_value argument for Linux is 0 (zero).
Flags_value Arguments for Red Hat Distribution
0 Halt. (Do not set init default to this value.)
1 Single-user mode.
2 Multiuser, without NFS (same as 3, if you do not have networking)
3 Full multiuser mode (Default)
4 Unused
5X11
6 Reboot. (Do not set init default to this value.)
Flags_value Arguments for SuSE Distribution
0 Halt. (Do not set init default to this value.)
S Single-user mode. (Default)
1 Multiuser without network
2 Multiuser with network
3 Multiuser with network and xdm
6 Reboot. (Do not set init default to this value.)
Single-user mode is typically used for troubleshooting. To make system changes at this run level, you must have read/write privileges. The command to boot Linux into single-user mode is similar to the following example, where “/” root is in partition 2 of DKA0, and the kernel is in /boot/compaq.gz.
P00>>> boot –file 2/b oot/co mpaq.g z –flags “root=/ dev/sd a2 rw s”
Example
This following command sets the boot_osflags environment variable for Linux:
P00>>> set boot_osflags 0
4-8 DS20E Reference Guide
Page 87
OpenVMS Systems
OpenVMS systems require an ordered pair as the flags_value argument: root_number and boot_flags.
root_number Directory number of the system disk on which OpenVMS files
are located. For example:
root_number
Root Directory
0 (default) [SYS0.SYSEXE]
1 [SYS1.SYSEXE]
2 [SYS2.SYSEXE]
3 [SYS3.SYSEXE]
boot_flags
The hexadecimal value of the bit number or numbers set. To specify multiple boot flags, add the flag values (logical OR). For example, the flag value 10080 executes both the 80 and 10000 flag settings. See Table 4–1.
Table 4–1 OpenVMS Boot Flag Settings
Flags_Value Bit Number Meaning
1 0 Bootstrap conversationally (enables you to
modify SYSGEN parameters in SYSBOOT).
2 1 Map XDELTA to a running system.
4 2 Stop at initial system breakpoint.
8 3 Perform diagnostic bootstrap.
10 4 Stop at the bootstrap breakpoints.
20 5 Omit header from secondary bootstrap image.
80 7 Prompt for the name of the secondary bootstrap
100 8 Halt before secondary bootstrap.

4.1.5 ei*0_inet_init or ew*0_inet_init
The ei*0_inet_init or ew*0_inet_init environment variable determines whether the interface’s internal Internet database is initialized from nvram or from a network server (through the bootp protocol). Legal values are nvram and bootp. The default value is bootp. Set this environment variable if you are booting Tru64 UNIX from a RIS server.
To list the network devices on your system, enter the show device command. The Ethernet controllers start with the letters “ei” or “ew,” for example, ewa0. The third letter is the adapter ID for the specific Ethernet controller. Replace the asterisk (*) with the adapter ID letter when using this command.
The syntax is:
set ei*0_inet_init value or set ew*0_inet_init value
The value is one of the following:
nvram
bootp
Initializes the internal Internet database from nvram.
Initializes the internal Internet database from a network server through the bootp protocol.
Example
P00>>> set ewa0_inet_init bootp
Booting and Installing an Operating System 4-11
Page 90
4.1.6 ei*0_protocols or ew*0_protocols
The ei*0_protocols or ew*0_protocols environment variable sets network protocols for booting and other functions.
To list the network devices on your system, enter the show device command. The Ethernet controllers start with the letters “ei” or “ew,” for example, ewa0. The third letter is the adapter ID for the specific Ethernet controller. Replace the asterisk (*) with the adapter ID letter when entering the command.
The syntax is:
set ei*0_protocols protocol_value or set ew*0_protocols protocol_value
The options for protocol_value are:
mop (default)
Sets the network protocol to mop (Maintenance Operations Protocol), the setting typically used with the OpenVMS operating system.
bootp
Sets the network protocol to bootp, the setting typically used with the Tru64 UNIX operating system.
bootp,mop
When both are listed, the system attempts to use the mop protocol first, regardless of which is listed first. If not successful, it then attempts the bootp protocol.
