Unsatisfactory Flash
Introduction
If the HLC’s firmware load ever becomes corrupted, or for troubleshooting
under the direction of a technician, SW2, position 3, allows you to change the
HLC’s execution mode and force the HLC to execute from the firmware load
shipped with the HLC, which resides on the E-PROM module.
To change the HLC’s execution mode via DIP switch setting
1 If you are not already logged in, log in to the MMI.
Note: See “LOGIN (L)” on page 91.
If you are already logged in, type PROVISION SAVE (P S) and press enter
to save the card’s most recent settings (provisioning entries).
2 Remove the HLC from the IPE shelf or Option 11 cabinet.
Set position 3 of DIP switch 2 (SW2) to the desired mode by selecting one
of the following options:
■
To force the HLC to execute from E-PROM, set SW2 position 3 to the
ON position.
■
To allow the HLC to execute from Flash, set SW2 position 3 to the OFF
position.
3
Reinsert the card.
4
Log in to the MMI.
5
Type DISPLAY CONFIGURATION (D C) and press enter to verify that the
HLC is running in the desired execution mode.
Note: You can equip Flash memory with a new firmware load while the DIP
switch is set to Force E-PROM, but for the HLC to execute from the new
firmware load in Flash memory, the SW2 position 3 must be set to OFF.
