Hardware Jumpers

At present, no hardware jumpers need to be fitted apart from those shipped with the product. No additional functionality or debugging information is derived from altering the default jumper positions. The default jumper positions should be:

491-G1 mother board

J1: A
J2: A
J3: not fitted

512-G1 daughter board

J1: not fitted
J2: not fitted
J3: not fitted

Booter Diagnostics

The booter program is available for use during the start-up of the system. Under normal operation, the user need not be concerned with booter operation, since it automatically identifies, loads, decompresses and executes the selected software files that have the attribute PRIMARY assigned to them. However, during unforeseen error conditions the booter can be used for diagnostic purposes.

491-G1 Motherboard

A connection to the "Booter" may be made by plugging a cable into the 9-pin D-type connector at the front of the motherboard, accessible after removing the front panel. This is an asynchronous interface running initially at 38400 bps, 8 character bits, no parity bit, 1 stop bit, XON/XOFF flow control.Once MON information is displayed the <RETURN> key can be pressed several times to autobaud to the current terminal speed.

Note that before a user issues a reset (by pressing the RESET button on the motherboard or after power down/up of the unit), various switches must be set on the motherboard to enter the Booter interface. The 8-position switch SW2 can be found near the front edge on the 491 motherboard.

WARNING: Do not use the DEBUG button.

Switch position

Operation

1

ON = stop in booter at the => prompt after reset
OFF = normal operation

2

ON = switches the cache off after reset
OFF = normal operation

3

ON = if a debug build is being used, this switches off all trace messages after reset
OFF = normal operation

4

ON = primary configuration script file does not load after reset
OFF = normal operation

5 Not used
6 Not used
7 Not used
8 Not used

Note that position 1 is at the far left. For standard system operation, all switch positions should be kept to OFF, i.e. nearest the debug and reset buttons.

The booter interface commands include:

  • fd - This displays the current status of the FLASH0 file system with respect to total storage size, free space (bytes and blocks) and files currently residing in the system. Files (*.APL, *.ROM, *.SCR and *.FRM) are listed with their respective file sizes, file types and attributes).

  • sl <filename> - This allows the serial loading of a file (via Z-MODEM) to the FLASH0 file system.Note that Intracom recommends terminals to be set to 9600 baud to serial load the TOOLKIT.ROM file.

  • fl <filename> - This loads and executes an application file (*.APL) from the FLASH0 file system. This is of use if you need to load a non-PRIMARY application file.

  • fz - This will completely erase the FLASH0 file system contents. It is recommended that new .APL, .ROM, and .FRM files are made available locally for Z-MODEM transfer via the sl command. CAUTION!!

512-G1 ATM daughter board

It is not envisaged that test personnel or developers need to access the booter of the Daughter board outside of Ericsson Intracom Ltd. However, for completeness, the information is outlined below.

A connection to the Daughter board may be made by plugging a cable into the 9-pin D-type connector at the front of the daughter board, accessible after removing the front panel. This is an asynchronous interface running at 9600 bps, 8 character bits, no parity bit, 1 stop bit, XON/XOFF flow control.

Note that before a user issues a reset (by pressing the RESET button on the daughter board or after power down/up of the unit), various switches must be set on the board to enter the booter interface.

The switch SW3 can be found near the front edge on the 512-G1 motherboard, to the right of the DEBUG button.

WARNING: Do not use the DEBUG button.

Switch position

Operation

1

ON = stop in monitor at the => prompt after reset
OFF = normal operation

2

ON = enables debugging information + output stops
OFF = normal operation

3

Not used

4

Not used

Note that the switch positions are numbered 1-4, with position 1 being at the far left of the switch. For standard system operation, all switch positions should be set to OFF.

Fan Replacement Procedure

A complete fan malfunction, or more typically fan wear (when e.g., the fan speed (rpm) is reduced by 30%), is indicated when either:

  • the front panel rightmost LED is lit (also check for PSU failure as the LED is also used for this)

  • an SNMP FANFAIL trap has been received at the SNMP management station.

In the event of fan failure, the "hot swap" fan on the AXI 510 Edge Router can be replaced when the unit is still powered on.

The fan can only be supplied as a spare part which is made available to the local ERICSSON company from Ericsson Intracom Ltd.

Procedure

Ensure all anti-static precautions are taken.

1) Unscrew the hot-swap fan screws - the screws have hexagonal captive head sockets and are located at either corner of the square fan mounting plate.

2) Carefully extract the fan assembly a few centimeters to expose the plastic inline connector.

4) Disconnect the fan by separating the two halves of the inline connector.

5) Attach new fan previously ordered.

6) Secure fan to rear panel.
