SAF-TE Command Implementation
If a device is not present in the slot, and this bit is set, power will
remain off. The Ready for Insertion/Removal bit will be set and the
Prepared for Operation bit will be cleared in the Read Device Slot
Status command.
These conditions apply if the Device Present option is
not
chosen in the
configuration program:
Power will be turned off, the Prepared for Operation bit will be
cleared, and the Ready for Insertion/Removal bit will be set in the
Read Device Slot Status command.
4.3.2.3 Identify
This will drive an external LED(s) according to the blink pattern for the
specific device slot. If one LED is chosen, the Identify Slot bit is set to
the fast blink rate. If two LEDs are chosen, the LED1 bit is set to the slow
blink rate and the LED2 bit is set to the fast blink rate.
4.3.3 Send Global Flags Command (0x15)
This command is used to send commands that apply to the enclosure.
The Read Global Flags command (
Table 4.14
) is used to read the most
current state of the global flags sent with this command:
