1.3 Mode Configuration

Apacer SRFD supports 4 static pins that can be used to program a normal operating state. The configuration

of each node uses a combination of the Configuration pins and the Pushbutton (Reset) pin.

Table 1-1: Mode Configuration

1.3.1 Definition

The following method can be used to define the configurations.

Configuration pins set to FAST (RAID-0), SAFE (RAID-1):

A. While the system is powered-up

I. Any configuration change is ignored

II. Physical drive change rules: no drivers accepted; in SAFE (RAID-1) mode, a single driver change

will be accepted with normal driver rules (larger or equal to existing drive)

B. Upon power-up, but with no pushbutton (reset) press

I. Any configuration change is ignored

II. Physical drive change rules: no drivers accepted; in SAFE (RAID-1) mode, a single driver change

will be accepted with normal driver rules (larger or equal to existing drive which must be present)

C. Upon power-up and momentary pushbutton (reset) pressed

I. Only new configuration changes are explicitly accepted (if possible) and all new drives are explicitly

accepted if there is a new configuration
