Goal

This article describes the process and requirements for interfacing to the RS232 or USB serial console on the back of a Axiom Brick.

Solution

Prerequisites

One (1) Brick Console Cable Kit.
One (1) Client computer with a RS232 or USB port.
One (1) RS232 or USB Terminal Application.

The Brick Console Cables can only be ordered as a kit, part number 1450-00290-30 Cable Kit, and contains the following:

• 6051-00081-00 PC to Brick Cable, 3.5MM Stereo Mini-Jack-M to DB9-F, 2.0M
• 6051-00097-00 USB to DB9 RS232 Cable, 6Ft

Details

Interface to the Brick console should only be conducted by authorized personnel. Significant adverse system impact, including irrecoverable data loss can occur if the procedures are not executed properly.

OVERVIEW OF HARDWARE:

The Brick Console port is a 1/8 Inch Mini Stereo Jack. There is one port per RAID Controller. The ports are circled in red in the following image:

This port is connected to a workstation Serial Port with a Console Cable (The cable may be supplied as two pieces, a Stereo to RJ-45 Telco Cable and a DB-9 to RJ-45 Telco Adapter. For systems without serial ports, a USB-Serial Convertor may be supplied).

The cable looks similar to the following image:

The following table describes the pin relationship between the DB9 connector and the 1/8 Inch Mini Stereo Jack.

INTERFACE PROCEDURE

1. Connect Stereo Plug end of the Brick Console Cable to the Mini Stereo Jack on a RAID controller or RC. RC0 is located on the right side - RC1 on the left side when facing the back of the brick.
2. Connect the opposite end (DB9 or USB) to the client computer by the appropriate means.
3. Open a RS232 / USB terminal application on the computer (i.e. Hyperterminal, Putty, etc.). If USB, determine the serial port number being emulated from device manager. 
4. Connect to the serial port with the following settings:
   
   1. 115200 Bits per Second
   2. 8N1 or 8 Bits, No Parity, 1 Stop Bit
   3. No Flow Control All hardware and software flow control must be disabled
   4. Configure the RS232 terminal application to capture all printable output from the session.  This is often useful in assisting Engineering with any possible bug fixes that might be associated with the problem.
5. Open the serial connection in your terminal application.
6. Press the enter key. If the connection is successful, a Password prompt should appear.

For all SATA and FC RAID controllers, the password is tardis. For FC Expansion controllers, the password is gemini. Enter the correct password to log into the brick.
