Figure 4 Display/Operation Panel

Liquid Crystal Display (LCD)

The 6500 display/operation panel’s LCD indicates real-time array status and
error conditions, and is used to enter a wide range of setup parameters and
operating commands. The LCD displays 2-line by 16-character messages, and
indicates the current position in a tree-structured menu of functions. (See
Chapter 3, Display/Operation Panel.)

RESET Switch

This switch initiates a reset, which returns the array to an initial power-up
condition. In this power-up state, the firmware and SCSI chip are initialized.
Caution The RESET switch initiates a subsystem restart; any activity in
progress will be halted without saving information.

SELECT Switch

The SELECT switch is used to initialize new function selections that appear
on the LCD display.

Navigation Switches (Up, Down, Left, Right)

The four “arrow” switches on the panel are used to step through options in the
tree-structured menu, and to make selections when available. Pressing
SELECT initializes the currently displayed option.
