RAS 2000 PowerRack Windows NT Supplement

RAS 2000 Softwa r e

The R A S 2 0 0 0 PowerRack int roduces a n ew system board wi t h several major
performa nce improvements. W hen compar e d to its pr edecessor, the IntelliSe rver
PowerRack, the RAS 2000 PowerRack boasts a RISC processor that runs 50%
faster, has double the cach e, a 10-Base- T ethernet control l er that h as d ouble the
throughp ut capacity, additional non- vo la tile me mory, and a writa ble ope rating
system flash through whic h up grades and bug fi xes can be loaded.

For this release, all opera tional function a l ity of the o ri g i nal PowerRack has been
ported over to the RAS 2000, with an exception that should reduce the load of
managing multip l e units. While BOOTP and TFTP fun ction ali t y ha ve been main­tained for c onfig uration file downloads, support for booting dire ctly f rom a TFTP
site has been repl aced with th e ability to d ow n lo ad and eit h er execute or save a
kernel image from a TFTP site. The main advantage to this is that kernel
upgrades no longer n eed to b e st or e d on a TFTP site and made ava il abl e continu­ously. They may be downloaded and stored permanently on the RAS 2000.

Features

The RAS 2000 PowerRack softwa re is almost identical in fe atures and functions
to the softwar e used on the original IntelliServer Pow e rRack. In o rder to get the
most out of the RAS 2000 Powe rRack's improv ed hardw are d es ig n, you should
be aware o f some importan t d ifferences betw een the In telliServer RA S 2000
PowerRack and the original IntelliServer PowerRack, as explained in this sec­tion.

The RA S 200 0 P owe rRa c k differe n ces are:

•

RISC pro cess or ( RISC- 860)

•

Software and configuration files

•

Port configuration

•

Facto ry defa ult

•

Great er 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 Power Rack, softwar e in te n de d f o r one cannot be loaded on the other.

Notes:

1) When getting upgrades from our FTP site, examine the 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. If you attempt to do this, the IntelliServer will report an 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 avail­able:

50 300 3600 56000 230400
75 600 4800 57600 307200

110 1200 7200 64000 460800

134.5 1800 9600 76800 921600
150 2000 19200 115200
200 2400 38400 153600

Port Numberin

On the R A S 2000 Po werRack, the CP U En gi n e card is installe d in the lowest slot
of the enclosure (s l ot 0). Slot 1 is ne x t to the proces s or c ard and alw ays contains
ports 0 t hrou g h 15. As you install additional p orts, u se sl o ts 2 throu g h 4 in order:

Slot 2 al w a y s contains ports 16-31
Slot 3 al w a y s contains ports 32-47
Slot 4 al w a y s contains ports 48-63

If for any reason it shoul d become nec ess a ry to remove o n e of the REX ca rd s, the
remaining ports keep the same numbers. If you remove a REX card out of the mid­dle, it leaves a gap in the port numbers that th e RA S 2000 PowerRac k recognizes.

Factory Defaults Differences

When the R A S 20 00 is u sing facto r y defau l t conf igur ation, the lo we st and the
highest port number in each slot are enable d as login p or ts and can be used for ini­tial configuration with a terminal. (In a 64-port installation, that would be ports 0,
8, 16, 24, 32, 40, 48, and 56.)

The RAS 20 0 0 Po w erRack uses unique software that i s not int erchangeable with
the other IntelliS e rver Powe r Rack models. The main dif fe rences are:

•

Windows NT support

•

Flashable kernel

NT RAS (Remote Access Service)

Typically, RAS servers are implemented in an NT environment using modem
attached to serial po rts local to th e N T se rver. Devi ces such as fax servers,
modem pool serve r s, and o ut bou n d fa x ser ver s are a few ap pl ication s th at would
use this available source of modem connections.

This design does not implement RAS or fax servers directly. Rather, it describes
the met hod by which a host machine may ga in effective control of a UART on
the RA S 2 00 0 PowerRac k . Once a host’s driver establishes communica t i on 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.

Upgrade Procedures

The RAS 2000 comes with the correct kernel version installed. As additional fea­tures are made available, kernel files will be posted on Computone’s FTP site in

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.

While th e cha nc es of a power fai lure d u r ing a kernel upg rade is remo t e, nonethe­less, it is po ssib le . Should this occur, th e im a ge i n the f lash is left in an in consis­tent state. The Em erge n cy B o ot Loader is de sign ed as a met h od of getting a
kernel load ed into me mo r y a n d executing and does not at te mpt t o sav e the image
to fla sh . Du r i n g the normal course of a power-u p seq ue nce, the boot loader per­forms sev er al integrity checks on the PR OM. It recognizes an inconsistent state
and invokes the Emergen c y B oot L o ad er. In doing so, the status LE D s on the
RAS 2000 (l a be le d with a cir cl e and rectan gle) light ye llow-red and stay on.

To correct this problem, you need a:

•

Computer with a communications program such as cu, Procomm, or Hyper­Terminal

•

.srec file that accompanies the kernel release

•

Cable to attach port 0 to a serial port on the compu t er (Computone cable
2-20121, for example)

Once y ou h av e e ver ythi ng conn ect ed, use the fol l owing p roc edure:

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:

There is a checksum error
in the kernel flash.
