RAS 2000 Software
The RAS 2000 PowerRack introduces a new system board with several major
performance improvements. When compared to its predecessor, the IntelliServer
PowerRack, the RAS 2000 PowerRack boasts a RISC processor that runs 50%
faster, has double the cache, a 10-Base-T ethernet controller that has double the
throughput capacity, additional non-volatile memory, and a writable operating
system flash through which upgrades and bug fixes can be loaded.
For this release, all operational functionality of the original PowerRack has been
ported over to the RAS 2000, with an exception that should reduce the load of
managing multiple units. While BOOTPand TFTP functionality have been main-
tained for configuration file downloads, support for booting directlyfrom a TFTP
site has been replaced with the ability to download and either execute or save a
kernel image from aTFTP site. The main advantage to this is that kernel
upgrades no longer need to be stored ona TFTP site and made available continu-
ously.They may be downloaded and stored permanently on the RAS 2000.

Features
The RAS 2000 PowerRack software is almost identical in features and functions
to the software used on the original IntelliServer PowerRack. In order to get the
most out of the RAS 2000 PowerRack's improved hardware design, you should
be aware of some important differences between the IntelliServer RAS 2000
PowerRack and the original IntelliServer PowerRack, as explained in this sec-
tion.
The RAS 2000 PowerRack differences are:
•RISC processor (RISC-860)
•Software and configuration files
•Port configuration
•Factory default
•Greater throughput
•Increased CPU speed (30 Mhz)
This section further explains these software differences.
Different Software
Because of the hardware differences between the IntelliServer PowerRack and
RAS 2000 PowerRack, software intended for one cannot be loaded on the other.

Notes:
1) When getting upgrades from our FTP site, examinethe file names and descriptions to
ensure you download the correct software.
2) You cannot save a configuration to a host and then restore it to a different model of
IntelliServer. Ifyou attemptto do this, the IntelliServer will reportan error, "Bad Magic
Number" which means that the file you are attempting to restore the configuration from
is not in the proper format.

Port Speeds
Because of improved hardware design, the RAS 2000 PowerRack supports line
speeds up to 921,600. When configuring a port, the following speeds are avail-
able:
Port Numberin
On the RAS 2000 PowerRack, the CPU Engine card is installed in the lowest slot
of the enclosure (slot 0). Slot 1 is next to the processor card and always contains
ports 0 through 15. As you install additional ports, use slots 2 through 4 in order:
Slot 2 always contains ports 16-31
Slot 3 always contains ports 32-47
Slot 4 always contains ports 48-63
If for any reason it should become necessary to remove one of the REX cards, the
remaining ports keep the same numbers. If you remove aREX card out of the mid-
dle, it leaves a gap in the port numbersthat the RAS 2000 PowerRack recognizes.
Factory Defaults Differences
When the RAS 2000 is using factory default configuration, the lowest and the
highest port number in each slot are enabled aslogin ports and can be used for ini-
tial configurationwith a terminal. (Ina 64-portinstallation, that would be ports 0,
8, 16, 24, 32, 40, 48, and 56.)
The RAS 2000 PowerRack uses unique software that is not interchangeable with
the other IntelliServer PowerRack models. The main differences are:
•Windows NT support
•Flashable kernel
50 300 3600 56000 230400
75 600 4800 57600 307200

NT RAS (Remote Access Service)
Typically, RAS servers are implemented in an NT environment using modem
attached to serial ports local to the NT server. Devices such as fax servers,
modem pool servers, and outbound fax servers are a few applications that would
use this available source of modem connections.
This design does not implement RAS or fax servers directly. Rather, it describes
the method by which a host machine may gain effective control of a UART on
the RAS 2000 PowerRack. Once a host’s driver establishes communication with
a RAS 2000 PowerRack, it attaches to one or more remote serial ports (RSP) and
presents them as "logical" serial ports to the host operating system. In the case of
NT, these appear as COM ports.
The following sections describe how to configure Remote Serial Ports on the
RAS 2000 and how to install the Windows NT driver.

Remote Serial Port Configuration
The purpose of this section is to provide a quick start reference for configuring
the RAS 2000 in a Windows NT environment. This document is not intendedasa
replacement for the spiral bound IntelliServer Configuration Guide.The IntelliS-
erver Configuration Guide should be referenced for detailed explanations of the
settings listed, as well as any settings listed as default/blank. This document
establishes quick start guidelines for the following topics.
•IntelliServer configuration
•Remote serial ports
•Saving your configuration
RAS 2000 Configuration
The IntelliServer line of products can be set up in a number of different ways. For
basic setup instructions and guidelines for your particular environment, refer to
the IntelliServer Configuration Guide (chapters 9 & 10) for detailed setup. The
following configuration information should be used in troubleshooting and initial
setup as a basic guideline. Once configured with a console, proceed with the fol-
lowing.

Upgrade Procedures
Upgrading the Kernel via Netbooting
The RAS 2000 comes with the correct kernel version installed. As additional fea-
tures are made available, kernel files will be posted on Computone’s FTP site in
the /pub/products/RAS 2000 directory. Use the following procedure to install a
new kernel:
1. Download the desired kernel version from Computone’s FTP site. Be sure to
use the BINARY transfer mode.
2. Place the file in your TFTP server’s directory.
3. Login on the RAS 2000 as root and enter the command netboot host filename
where host is the name of the IP address of the TFTP server on which the file
is stored and filename is the name of the file as it’s stored on that server.
4. Login as root and enter the command netboot -s host filename after the
RAS 2000 reboots. The -s option causes the downloaded kernel to be saved to
nonvolatile memory without the RAS 2000 rebooting again.
End of Procedure
Emergency Boot Loader
While the chances of a power failure during a kernel upgrade is remote, nonethe-
less, it is possible. Should this occur, the image in the flash is left in an inconsis-
tent state. The Emergency Boot Loader is designed as a method of getting a
kernel loaded into memory and executing and does not attempt to save the image
to flash. During the normal course of a power-up sequence, the boot loader per-
forms several integrity checks on the PROM. It recognizes an inconsistent state
and invokes the Emergency Boot Loader. In doing so, the status LEDs on the
RAS 2000 (labeled with a circle and rectangle) light yellow-red and stay on.

RAS 2000 PowerRack Windows NT Supplement Page 15
To correct this problem, you need a:
•Computer with a communications program such as cu, Procomm, or Hyper-
Terminal
•.srec file that accompanies the kernel release
•Cable to attach port 0 to a serial port on the computer (Computone cable
2-20121, for example)
Once you have everything connected, use the following procedure:
1. Specify 9600 baud, no parity, 1 stop bit, 8 data bits, and no handshaking for
the serial port.
2. Power up the RAS 2000. You should get the following message:
If you do not get this prompt, double-check all cabling and communication
parameters. When you call tech support, this is the first thing they will ask you.
3. Enter “?”, the following is displayed:
You get a list of valid commands any time you enter an invalid command. The
commands are defined as follows:
There is a checksum error
in the kernel flash.
Emergency Boot Loader

Command Description
reset Resets RAS 2000.
baud <baudrate> Sets baud rate on-the-fly. Once entered, you have to change the
terminal’s baud rate and press enter to get another prompt. If you
enter an invalid baud rate, a list of valid baud rates are displayed.
load Starts kernel load.

Page 16 RAS 2000 PowerRack Windows NT Supplement
4. Enter load and press enter to start receiving the kernel. The following is
displayed:
If all goes well, the .srec file is sent in a plain ASCII transfer format. Upon
uploading, the image is executed.
NOTE: This does not fix the original corruption in the flash, it just gets a kernel
loaded and executing. Once the kernel is up and running, netboot to attempt
another save of the kernel image.
5. Netboot to load and save a new kernel image (see section, Upgrading the
Kernel via Netbooting).
End of Procedure
Restoring Factory Defaults
There are three ways to restore factory defaults to NVRAM:
1. Enter restore factory at the shell command prompt.
2. Hold the paperclip button down while powering up the RAS 2000. Release it
after 1 second.
3. Connect a terminal to port 0, at 9600 baud, 8-bit characters, no parity, and 1
stop bit. and then press the ESC key while the RAS 2000 is booting (at
power-up or after a "shutdown" command).
Even if you use method 2, it is recommended that you have a terminal or PC
attached to port 0. The reason is that the machine has no IP address and, thus, is
not accessible over the network. None of the methods above alter NVRAM so if
you want the old one back, do a restore, shutdown now, or a power cycle. If you
want to save the factory defaults, type insave just as you would when saving any
other configuration.
Figure 7 shows the location of the paperclip button to restore factory defaults.
EBL< load
Press ESC to stop the load
