Chapter 1 - Getting Started
Spin-Up Settings
11
For example, if the setting for switches 1 through 3 are “Down.” the device ID addresses
for the drive slots 1 - 12 would be 0 - 11 respectively.
NOTE:
If a hard address ID conflict occurs during Fibre Channel loop initialization, the
Fibre Channel protocol will dynamically set the drive IDs. This could cause
problems with some software products.
Switches 4, 5, and 6 are not used.
Spin-Up Settings
Switches 7 and 8 control the drive spin-up functions. The switches are directly attached to
all of the drive slot start signals. Switch 7 controls the “Start_1” signal (Delay Spin-up) and
switch 8 controls the “Start_2” signal (Remote Spin-up).
The table below describes the function of each switch.
