Shutdown" on page
Shutting down the system can take up to 15 minutes. The server goes into standby
mode, its power-off indicator lights up green.
4. After the server has switched off itself, also the ETERNUS DX100 S3 storage module
should switched off. Therefore press and hold the power ON/OFF button of the storage
base module for at least 4 seconds until the READY LED does not glow any more. Then
wait a few minutes until DX100 S3 has shut down (its power LED goes off).
5. Depending on the needs, relocate the existing modules or just mount the new ones in
the rack according to the numbering scheme of the modules. The sequence of the
modules should be as shown in figure
Rack for Scale" on page
CAUTION!
If you have to unmount or to relocate the existing modules, ensure not to
change their order. Double check the labels, see step 2.
6. The SAS cabling of the ETERNUS DX100 S3 storage modules has to be prepared in the
form of a so called reverse cabling: The cabling chain behind CM#0 of the CE module
goes from the first to the last DE while the chain behind CM#1 goes from the last to
the first DE.
The last DE is the DE with the always highest identifier in the range of DE-1 to DE-a
(i.e. the always most recently added one). That means that expanding a system with
at least one already existing DE requires moving the end of the cable connected to
CM#1 from the IOM#1 IN port of the priorly last DE to the IOM#1 IN port of the new last
DE.
