System Drawer Overview
Architecture
The system bus, with its logic on the system motherboard, connects the
CPU, memory, and system bus to PCI bus bridge modules. The two 64-bit
PCI buses eac h have four sl ots f or P CI opti ons. ( Three of the eight slots can
be used for either PCI or EISA options.)

System Drawer Overview
The system bus is a 144-bit data bus (128 bits for data and 16 for ECC) and a separate 40bit command/address bus. The logic is on the system motherboard. This bus connects CPU
modules, memory modules, and the system bus to PCI bus bridge module. The clock for
the system bus is on the module in CPU slot 0.
CPU modules are available with and without an external cache. The Alpha chip has an 8KB instruction cache, an 8-KB write-through data cache, and a 96-KB-write-back
secondary data cache. The on-board cache version of the module has a 2- or 4-MB data
cache. The default cache system is write-back. The system drawer supports up to four
CPUs.
A memory pair is two modules of the same size and type, which together comprise one
memory option. Memory pairs can be 128 or 512 MB or 1 GB. Each module in the pair
drives 72 bits of the 144-bit system bus. The system drawer can have up to four memory
pairs.
The system bus to PCI bus bridge module supports two 64-bit PCI buses. One PCI bus
has four slots for PCI options; the other has one dedicated PCI slot and three slots that can
be used for either PCI or EISA options.

System Drawer Overview
The console terminal can be a serial (character cell) terminal connected to the COM1 port
or a graphics monitor connected to a VGA adapter on PCI0. If the console terminal is
connected to COM1, the entire power-up display prints. (See the section “Power-Up
Display” for information about the power-up display.) If the console terminal is a VGA
monitor, console power-up messages are sent to either of those devices but SROM and
XSROM power-up messages are lost.
When the console terminal is a serial terminal, the console environment variable is set to
serial. When it is a graphics monitor, console is set to graphics. (See “Environment
Variable Summary” in Chapter 5 for information about environment variables.)
NOTE: Regardless of the setting of the console environment variable, all three
power-up programs send messages to the control panel display.
If the console environment variable is set to serial and no terminal is attached to COM1,
pressing a carriage return on a graphics terminal attached to the keyboard port makes it the
console device and the console prompt is sent to it.
If the console environment variable is set to graphics and no graphics monitor is attached
to the keyboard port, pressing a carriage return on a serial terminal attached to COM1
makes it the console device and the console prompt is sent to it.
NOTE: The console prompt displays only after the entire power-up sequence is
complete. This can take up to several minutes if the memory is very
large.

➊
On power-up, the SROM code on each CPU module loads into that module’s Icache and tests the processor chip. If all tests pass, the module’s LED lights. If
any test fails, the LED remains clear and power-up terminates.
The primary CPU is determined for the first of three times. The primary CPU then
executes a loopback test on each PCI bridge. If this test passes, the bridge LED
lights. If it fails, the LED remains clear and power-up continues. The EISA
system controller, PCI-to-EISA bridge, COM1 port, and control panel port are all
initialized.
Each CPU prints an SROM message to the device attached to the COM1 port and
to the control panel display. (The banner prints to the COM1 port if the console
environment variable is set to serial. If it is set to graphics, nothing prints to the
console terminal, only to the control panel display, until ➏. See “Environment
Variable” summary in Chapter 5 for information about environment variables.)
➋
The S-cache on each CPU module is initialized, and the XSROM code in the
FEPROM on the PCI motherboard is unloaded into them. (If the unload is not
successful, the SROM unloads XSROM code from a different FEPROM sector. If
the second try fails, the CPU hangs.)
Each CPU starts the XSROM code, which prints an XSROM message to the
COM1 port and to the control panel display.
➌
The three S-cache banks on each CPU are enabled, and the B-cache is tested. If a
failure occurs, a message is printed to the COM1 port and to the control panel
display immediately.
Each CPU prints a B-cache completion message to COM1.
➍
The primary CPU is determined for the second time. It then sizes memory.
Information on memory pairs is printed to the COM1 port. If an illegal memory
configuration is detected, a warning message is printed to the COM1 port and the
control panel display.
➎
Memory is initialized and tested, and test traces are printed to the COM1 port and
the control panel display. (The numbers for tests 20 and 21 might appear
interspersed; this is normal behavior. Test 24 can take several minutes if the
memory is very large. The message “P0 TEST 24 MEM**” is displayed on the
control panel display; the second asterisk rotates to indicate that testing is
continuing. All CPUs in a multiprocessor system share the memory testing to
minimize test time.) If a failure occurs, a message is printed to the COM1 port and
to the control panel display immediately.
Each CPU prints a test completion message to the COM1 port.

The primary CPU is determined for the last time. The primary CPU unloads
PALcode and decompression code from the FEPROM on the PCI motherboard to
its B-cache. The primary CPU then jumps to the PALcode to start the SRM
console.
The primary CPU prints a message indicating that it is running the console.
Starting with this message, the power-up display is printed to any console
terminal, regardless of the state of the console environment variable. (If console is
set to graphics, the display from here to the end is saved in a memory buffer and
printed to the graphics monitor after the PCI buses are sized and the VGA device
is initialized.)

display
The display command shows the physical configuration of the system. Display is
equivalent to issuing the SRM console command show configuration. Because it shows
the slot for each module, display can help you identify the location of a device.
exit
The exit command terminates the LFU program, causes system initialization and testing,
and returns the system to the console from which LFU was called.

The lfu command restarts the LFU program. This command is used when the update files
are on a floppy disk. The files for updating both console firmware and I/O firmware are
too large to fit on a 1.44 MB disk, so only one type of firmware can be updated at a time.
Restarting LFU enables you to specify another update file.
list
The list command displays the inventory of update firmware on the CD-ROM, network, or
floppy. Only the devices listed at your terminal are supported for firmware updates.
The list command shows three pieces of information for each device:
1. Current Revision — The revision of the device’s current firmware
2. Filename — The name of the file used to update that firmware
3. Update Revision — The revision of the firmware update image
DIGITAL Server 7300/7300R Series

Operation
readme
update
verify
The readme command lists release notes for the LFU program.
The update command writes new firmware to the module. Then LFU automatically
verifies the update by reading the new firmware image from the module into memory and
comparing it with the source image.
To update more than one device, you may use a wildcard but not a list. For example,
update k* updates all devices with names beginning with k, and update * updates all
devices. When you do not specify a device name, LFU tries to update all devices; it lists
the selected devices to update and prompts before devices are updated. (The default is no.)
The -all option eliminates the update confirmation requests, enabling the update to
proceed without operator intervention.
CAUTION: Never abort an update operation. Aborting corrupts the firmware on the module.
The verify command reads the firmware from the module into memory and compares it
with the update firmware. If a module already verified successfully when you updated it,
but later failed tests, you can use verify to tell whether the firmware has become
corrupted.

DIGITAL Server 7300/7300R Series
Operating the System Remotely
The remote console monitor (RCM) is used to monitor and control the
system remotely. The RCM resides on the server control module (see
Chapter 1) and allows the system administrator to connect remotely to a
managed system through a modem, using a serial terminal or terminal
emulator.
RCM Console Overview
The RCM has special console firmware that is used to remotely control an AlphaServer
system. The RCM firmware resides on an independent microprocessor. It is not part of
the SRM console that resides in the flash ROM. The RCM firmware has its own command
interface that allows the user to perform the tasks that can usually be done from the
system's serial console terminal. RCM console commands are used to reset, halt, and
power the system on or off, regardless of the operating system or hardware state. The
RCM console commands are also used to monitor the power supplies, temperature, and
fans.
The user can enter the RCM console either remotely or through the local serial console
terminal. Once in command mode, the user can enter commands to control and monitor
the system.
Operation
To enter the RCM console remotely, the user dials in through a modem, enters a password,
and then types a special escape sequence that invokes RCM command mode. You must
set up the modem before you can dial in remotely. See the section “Modem Dialog
Details” later in this chapter.
To enter the RCM console locally, the user types the escape sequence at the SRM console
prompt on the local serial console terminal.
The RCM also provides an autonomous dial-out capability when it detects a power failure
within the system. When triggered, the RCM dials a paging service at 30-minute intervals
until the administrator clears the alert within the RCM.

Modem Usage
To use the RCM to monitor a system remotely, first make the c onnections to
the server control module, as shown below. Then configure the modem port
for dial-in.

PK-0762-96
Modem Selection
The RCM requires a Hayes-compatible modem. The controls that the RCM sends to the
modem have been selected to be acceptable to a wide selection of modems. The modems
that have been tested and qualified include:
• Motorola LifeStyle Series 28.8
• AT&T DATAPORT 14.4/FAX
• Zoom Model 360
The U.S. Robotics Sportster DATA/FAX MODEM is also supported, but requires some
modification of the modem initialization and answer strings. See “Modem Dialog
Details,” later in this chapter.
Modem Configuration Procedure
Connect a Hayes-compatible modem to the RCM as shown in Figure 2-5, and power up
the modem.
From the local serial console terminal, enter the RCM firmware console by typing the
following escape sequence:
^]^]rcm
Operation
The character “^” is created by simultaneously holding down the Ctrl key and pressing the
] key (right square bracket). The firmware prompt, RCM>, should now be displayed.
Enter a modem password with the setpass command. See “RCM Commands,” later in this
chapter.
Enable the modem port with the enable command. See “RCM Commands.”
Enter the quit command to leave the RCM console.
You are now ready to dial in remotely.
DIGITAL Server 7300/7300R Series
2–33
Operation
Dialing In to the RCM Modem Port
Dial the modem connected to the server control module. The RCM answers the call and
after a few seconds prompts for a password with a “#” character.
Enter the password that was loaded using the setpass command. The user has three tries to
correctly enter the password. On the third unsuccessful attempt, the connection is
terminated, and as a security precaution, the modem is not answered again for 5 minutes.
On successful entry of the password, the RCM banner message “RCM V1.0” is displayed,
and the user is connected to the system COM1 port. At this point the local terminal
keyboard is disabled except for entering the RCM console firmware. The local terminal
displays all the terminal traffic going out to the modem.
To connect to the RCM firmware console, type the RCM escape sequence.
Refer to Example 2–8 for an example of the modem dial-in procedure.
A sample dial-in dialog would look similar to the following:

The escape sequence is not echoed on the terminal.
RCM> !RCM prompt is displayed. Commands to control and
monitor the system can be entered.
Terminating a Remote Console (Modem) Session
Terminate the modem session by executing a hangup command from the RCM console
firmware. This will cleanly terminate the modem connection.
If the modem connection is terminated without using the hangup command, or if the line
is dropped due to phone line problems, the RCM will detect carrier loss and initiate an
internal hangup command. This process can take a minute or more, and the local terminal
will be locked out until the auto hangup process completes.
If the modem link is idle for more than 20 minutes, the RCM initiates an auto hangup.

Entering and Leaving Command Mode
Use the default escape sequence to enter RCM command mode for the fi rst
time. You can enter RCM command mode from the SRM console level, the
operating system level, or an application. The RCM quit command
reconnects the terminal to the system console port.

DIGITAL Server 7300/7300R Series
2–37
Operation
alert_clr
alert_dis
alert_ena
The alert_clr command clears an alert condition within the RCM. The alert enable
condition remains active, and the RCM will again enter the alert condition when it detects
a system power failure. See “Dial-Out Alerts” later in this chapter.
RCM>alert_clr
The alert_dis command disables RCM dial-out capability. It also clears any outstanding
alerts. (See “Dial-Out Alerts,” later in this chapter.) The alert disable state is nonvolatile.
Dial-out capability remains disabled until the alert_enable command is issued.
RCM>alert_dis
The alert_ena command enables the RCM to automatically dial out when it detects a
power failure within the system. The RCM repeats the dial-out alert at 30-minute intervals
until the alert is cleared. The alert enable state is nonvolatile. Dial-out capability remains
enabled until the alert_disable command is issued.
RCM>alert_ena
In order for the alert_enable command to work, two conditions must be met:
A modem dial-out string must be entered with the system console.
Remote access to the RCM modem port must be enabled with the enable command.
See “Dial-Out Alerts” later in this chapter.
If the alert_enable command is entered when remote access is disabled, the following
message is returned:
*** error ***
2–38
DIGITAL Server 7300/7300R Series
disable
enable
Operation
The disable command disables remote access to the RCM modem port.
RCM>disable
The module’s remote access default state is DISABLED. The modem enable state is
nonvolatile. When the modem is disabled, it remains disabled until the enable command
is issued. If a modem connection is in progress, entering the disable command terminates
it.
The enable command enables remote access to the RCM modem port. It can take up to 10
seconds for the enable command to be executed.
RCM>enable
The module’s remote access default state is DISABLED.
The modem enable state is nonvolatile. When the modem is enabled, it remains enabled
until the disable command is issued.
The enable command can fail for two reasons:
hangup
There is no modem access password configured.
The modem is not connected or is not working properly.
If the enable command fails, the following message is displayed:
*** ERROR - enable failed ***
The hangup command terminates the modem session. When this command is issued, the
remote user is disconnected from the server. This command can be issued from either the
local or remote console.
RCM>hangup
DIGITAL Server 7300/7300R Series

Operation
halt
help or ?
poweroff
The halt command attempts to halt the managed system. It is functionally equivalent to
pressing the Halt button on the system operator control panel to the “in” position and then
releasing it to the “out” position. The RCM console firmware exits command mode and
reconnects the user’s terminal to the server’s COM1 serial port.
RCM>halt
Focus returned to COM port
NOTE: Pressing the Halt button has no effect on systems running Windows NT.
The help or ? command displays the RCM firmware command set.
The poweroff command requests the RCM module to power off the system It is
functionally equivalent to turning off the system power from the operator control panel.
RCM>poweroff
If the system is already powered off, this command has no effect.
The external power to the RCM must be connected in order to power off the system from
the RCM firmware console. If the external power supply is not connected, the command
will not power the system down, and displays the message:
*** ERROR ***
2–40
DIGITAL Server 7300/7300R Series
poweron
quit
Operation
The poweron command requests the RCM module to power on the system. For the
system power to come on, the following conditions must be met:
AC power must be present at the power supply inputs.
The DC On/Off button must be in the “on” position.
All system interlocks must be set correctly.
The RCM firmware console exits command mode and reconnects the user’s terminal to the
system console port.
RCM>poweron
Focus returned to COM port
NOTE: If the system is powered off with the DC On/Off button, the system will
not power up. The RCM will not override the “off” state of the DC
On/Off button. If the system is already powered on, the poweron
command has no effect.
The quit command exits the user from command mode and reconnects the user’s terminal
to the system console port. The following message is displayed:
Focus returned to COM port
The next display depends on what the system was doing when the RCM was invoked. For
example, if the RCM was invoked from the SRM console prompt, the console prompt will
be displayed when you enter a carriage return. Or, if the RCM was invoked from the
operating system prompt, the operating system prompt will be displayed when you enter a
carriage return.
DIGITAL Server 7300/7300R Series
2–41
Operation
reset
setesc
The reset command requests the RCM module to perform a hardware reset. It is
functionally equivalent to pressing the Reset button on the system operator control panel.
RCM>reset
Focus returned to COM port
The following events occur when the reset command is executed:
The system restarts and the system console firmware reinitializes.
The console exits RCM command mode and reconnects the user’s terminal to the server’s
COM1 serial port.
The power-up messages are displayed, and then the console prompt is displayed or the
operating system boot messages are displayed, depending on the state of the Halt button.
The setesc command allows the user to reset the default escape sequence for entering
console mode. The escape sequence can be any character string. A typical sequence
consists of 2 or more characters, to a maximum of 15 characters. The escape sequence is
stored in the module’s on-board NVRAM.
NOTE: If you change the escape sequence, be sure to record the new sequence.
Although the module factory defaults can be restored if the user has
forgotten the escape sequence, this involves accessing the server
control module and moving a jumper.
The following sample escape sequence consists of five iterations of the Ctrl key and the
letter “o”.
RCM>setesc
^o^o^o^o^o
RCM>
2–42
DIGITAL Server 7300/7300R Series
setpass
Operation
If the escape sequence entered exceeds 15 characters, the command fails with the message:
*** ERROR ***
When changing the default escape sequence, avoid using special characters that are used
by the system’s terminal emulator or applications.
Control characters are not echoed when entering the escape sequence. To verify the
complete escape sequence, use the status command.
The setpass command allows the user to change the modem access password that is
prompted for at the beginning of a modem session. The password is stored in the module’s
on-board NVRAM.
RCM>setpass
new pass>*********
RCM>
The maximum password length is 15 characters. If the password entered exceeds 15
characters, the command fails with the message:
*** ERROR ***
The minimum password length is one character, followed by a carriage return. If only a
carriage return is entered, the command fails with the message:
*** ERROR - illegal password ***
If the user has forgotten the password, a new password can be entered.

Dial-Out Alerts
The RCM can be configured to automatically dial out through the modem
(usually to a paging service) when it detects a power failure within the
system. When a dial-out alert is triggered, the RCM initializes the modem
for dial-out, sends the dial-out string, hangs up the modem, and
reconfigures the modem for dial-in. The RCM and modem must continue to
be powered, and the phone line must remain active, for the dial-out alert
function to operate.

DIGITAL Server 7300/7300R Series
Composing a Modem Dial-Out String
The modem dial-out string emulates a user dialing an automatic paging service. Typically,
the user dials the pager phone number, waits for a tone, and then enters a series of
numbers.
The RCM dial-out string (Example 2–11) has the following requirements:
The entire string following the set rcm_dialout command must be enclosed by quotation
marks.
The characters ATDT must be entered after the opening quotation marks. Do not mix
case. Enter the characters either in all uppercase or all lowercase.
Enter the character X if the line to be used also carries voice mail. Refer to the example
that follows.
The valid characters for the dial-out string are the characters on a phone keypad: 0–9, *,
and #. In addition, a comma (,) requests that the modem pause for 2 seconds, and a
semicolon (;) is required to terminate the string.
Elements of the Dial-Out String
ATXDT AT = Attention
X = Forces the modem to dial “blindly” (not look for a dial tone).
Enter this character if the dial-out line modifies its dial tone when
used for services such as voice mail.
D = Dial
T = Tone (for touch-tone)
, = Pause for 2 seconds.
Operation
9, In the example, “9” gets an outside line. Enter the number for an
outside line if your system requires it.

Operation
Resetting the RCM to Factory Defaults
If the escape sequence has been forgotten, you can reset the controller to
factory settings.
Reset Procedure
1. Power down the server and access the server control module, as follows:
Expose the PCI bus card cage. Remove three Phillips head screws holding the cover
in place and slide it off the drawer. If necessary, remove several PCI and EISA
options from the bottom of the PCI card cage until you have enough space to access
the server control module.
2. Unplug the external power supply to the server control module.
Locate the password and option reset jumper. The jumper number, which is etched on
the board, depends on the revision of the server control module.
NOTE: If the RCM section of the server control module does not have an
orange relay, the jumper number is J6. If the RCM section of the
server control module has an orange relay, the jumper number is
J7.
3. Move the jumper so that it is sitting on both pins.
4. Replace any panels or covers as necessary so you can power up the system. Press the
Halt button and then power up the system to the SRM console prompt. Powering up
with the password and option reset jumper in place resets the escape sequence,
password, and modem enable states to the factory default.
5. When the console prompt is displayed, power down the system and move the

Modem Dialog Details
This section provides further details on the dialog between the RCM and the
modem and is intended to help you reprogram your modem if necessary.
Phases of Modem Operation
The RCM is programmed to expect specific responses from the modem during four phases
of operation:
• Initialization
• Ring detection
• Answer
• Hang-up
The initialization and answer command strings are stored in the RCM NVRAM. The
factory default strings are:
Initialization string: AT&F0EVS0=0S12=50<cr>
Answer string ATXA<cr>
Operation
NOTE: All modem commands must be terminated with a <cr> character (0x0d
Initialization
The RCM initializes the modem to the following configuration:
Factory defaults (&F0)
No Echo (E)
Numeric response codes (V)
No Auto Answer (S0=0)
Guard-band = 1 second (S12=50)
Fixed modem-to-RCM baud rate
Connect at highest possible reliability and speed
The RCM expects to receive a “0<cr>” (OK) in response to the initialization string. If it
does not, the enable command will fail.
hex).
DIGITAL Server 7300/7300R Series
2–51
Operation
This default initialization string works on a wide variety of modems. If your modem does
not configure itself to these parameters, the initialization string will need to be modified.
See the topic in this section entitled Modifying Initialization and Answer Strings.
Ring Detection
The RCM expects to be informed of an in-bound call by the modem signaling the RCM
with the string, “2<cr>” (RING).
Answer
When the RCM receives the ring message from the modem, it responds with the answer
string. The “X” command modifier used in the default answer string forces the modem to
report simple connect, rather than connect at xxxx. The RCM expects a simple connect
message, “1<cr>” (CONNECTED). If the modem responds with anything else, the RCM
forces a hang-up and initializes the modem.
The default answer string is formatted to request the modem to provide only basic status.
If your modem does not provide the basic response, the answer string, and/or initialization
string will need to be modified. See the topic in this section entitled Modifying
Initialization and Answer Strings.
After receiving the “connect” status, the modem waits for 6 seconds, and then prompts the
user for a password.
Hangup
When the RCM is requested to hang up the modem, it forces the modem into command
mode and issues the hangup command to the modem. This is done by pausing for a
minimum of the guard time, sending the modem “+++”. When the modem responds with
“0<cr>” (OK), the hang-up command string is sent. The modem should respond with
“3<cr>” (NO CARRIER). After this interchange, the modem is reinitialized in
preparation for the next dial-in session.

Modifying Initialization and Answer Strings
The initialization and answer strings are stored in the RCM’s NVRAM. They come preprogrammed to support a wide selection of modems. In the circumstance where the
default initialization and answer strings do not set the modem into the desired mode, the
following SRM set and show commands are provided to enable the user to define and
examine the initialization and answer strings.
To replace the initialization string:
P00>>>set rcm_init " new_init_string"
To replace the answer string:
P00>>>set rcm_answer "new_answer_string"

Troubleshooting
System Drawer Does Not Power Up
When the system drawer does not power up, the problem may be a
disconnected power cord, a faulty fan, or a disengaged cover interlock.
Figure 3-1 Location of Cover Interlocks
If the system drawer does not power up
• Is the system drawer power cord plugged into the power strip? Is it secure in the
system drawer connector?
• Is the pedestal or cabinet AC power cord plugged in?
• Are the covers on the system drawer closed and the interlocks engaged?
• The cover interlocks must be engaged to enable power-up. See Figure 3-1 for
interlock locations. (The three interlocks are all in the area highlighted in the
illustration.)
• Is the power supply operating?

Troubleshooting
Control Panel Display Is Blank
If the system drawer powers up but the control pane l display is bl ank, the
problem may be a CPU module, the bridge module, the PCI mother board,
the control panel display, or the cable connecting the P CI motherboard and
the display.

If the system drawer powers up but the control panel display is blank
• Did all Self-Test Pass (STP) LEDs on the CPU modules light? See Figure 3-3 for the
location of these LEDs.
NOTE: Running AlphaBIOS causes the CPU STP LEDs to turn off. This is
normal behavior.
• If all STP LEDs are on, check the connection between the PCI motherboard and the
control panel. If the cable is connected and not damaged, the fault may be in either the
PCI motherboard or the control panel.
• If all STP LEDs are off and the DC_OK LED is on, the fault may be the CPU module
or, less likely, the motherboard.
• Did all “OK” LEDs (DC_OK, POWER_FAN_OK, and TEMP_OK) on the CPU
modules light?
• If any OK LED is off, the fault may be in the power system. Check the power
supplies, power control module, and all connections to both.
• Did all STP LEDs on the bridge module light?
• If all bridge STP LEDs are off, the fault is likely the motherboard or the bridge
module. Another possible, but less likely, cause may be the oscillator on CPU 0. If
this is a multiprocessor system, insert a different module in the CPU 0 slot.
Troubleshooting
• If one bridge STP LED is off, the fault may be the bridge module or the motherboard.
NOTE: In all cases listed above, the memory modules can be ruled out as a
possible cause.
