Figure 3-3 SAS cable
Careful planning should be done to avoid damage to the SAS cables, consider the following
precautions:
When you route the cable along a folding cable-management arm, leave enough slack in
the cable.
Route the cable away from places where it can be damaged by other devices in the rack
cabinet.
Do not put excess weight on the cable at the connection point. Make sure that the cable is
well supported.
To connect a mini-SAS cable, insert the mini-SAS connector into a mini-SAS port. Make sure
that it locks into place.
To remove a mini-SAS cable, complete the following steps:
1. Put one finger into the hole on the blue plastic tab on the mini-SAS connector and gently
pull on the tab to release the locking mechanism.
2. As you pull on the tab, pull out the connector to remove it from the port
Attention: Care should be taken to not use the cable for leverage when removing the
cable from the mini-SAS port.
In Figure 3-4 on page 37 we show an example of SAS connections being made to direct
attached hosts and a bladecenter through it internal SAS switch module. The DS3500 comes
with two standard built-in SAS ports per controller; and this figure show the system with the
additional option daughter card for the additional two ports per controller.
