Hi,

You require the Shelf ID Expander Cable in such case. Generally around 3 Cables will be shipped along with the new Controllers. These cable will not come with new Enclosure purchased.

With the help of Sheld ID expander cable you can cascade it to existing cable so that you will get 3 more ports so that you can connect 2 more enclosures.

Hi MAH,

Please see hardware configuration guide of your EVA to view how cables should be connected.

I have enough port to connect the shelf ID exapander cable on the TOP. Can I remove the TOP terminator and disconncet the cable and connect to the bottom , while the EVA is Online.? Then I can conncet the 3rd disk enclosure below .

Or it will effect the EVA configuration??

Removing Terminators will not cause any issue in EVA. All enclosures may become ID numbers with "0" (I checked with Bottom terminator removed).

You can join the cable on Top and add the new enclosure.
