Powering on the Altos S300 series
enclosure
This section describes how the Altos S300 series enclosure is powered
on. Jumpers installed on the I/O modules determine how the enclosure
powers up and how the disk drives spin up. The following section
describe the jumper settings.
Altos S300 series jumper settings
The Altos S300 series enclosure jumpers are located on the I/O Modules
(ESM and CSM). By installing or removing these jumpers the following
options may be set.
Note: For information on the I/O module LED, see page 20.
Power up
With this option enabled, the enclosure will power up automatically
when the host system is powered on.
To power up the enclosure with this feature enabled:
1.
Connect the cables between the enclosure and the host system.
2.
Switch on the enclosure (switches on PSU's at rear of enclosure).
3.
Power on the host system and the enclosure will power on also.
To disable this option, install a jumper at location JP13 on the ESM and
CSM (whichever is installed). If two CSMs are installed, the jumper
should be installed on both CSMs.
Remote start up
If you select this option, the disk drives will not spin up until a spin up
command is issued by the host system (even though the enclosure is
powered on). To enable this feature, install a jumper at location JP12
on the ESM and CSM (whichever is installed). If two CSMs are installed,
the jumper should be installed on both CSMs.
