, the Power Control Switch, if set ON, means that this 2104 Model DL1
does not automatically switch on or off when the host machine is switched on or off.
If you want this 2104 Model DL1 to switch on automatically when the host machine
is switched on, set this switch OFF.
Switch

is not used and can be set either OFF or ON.
Switch

, the Enable Enclosure Services Switch, and Switch
4
, the Select
Enclosure Services Switch, should both be set ON to allow ANSI SCSI-3 Enclosure
Services (SES) to operate.
Note: The switch card has other switches that are accessible only when the switch
card is removed from the 2104 disk enclosure.
One of these switches is used to indicate whether the disk enclosure is a
2104 Model DL1 or a 2104 Model TL1, and another allows the order of the
SCSI addresses of the disk drive modules to be reversed.
More information about these switches is given in the IBM Expandable
Storage Plus: 2104 Service Guide, GY33-0194
