Adding a 0C6D to and EVA
I am going to add an expansion rack (0C6D to an EVA .
My questions are :
I should remove the top terminator and connect the CANbus cab-to-cab cable and run this cable to the expansion rack and connect the top terminator now at the end of the EAB.
Can I do this online.

Re: Adding a 0C6D to and EVA
Theoretically, interrupting the CAB should not effect the EVA in anyway except that you will likely get multiple alarms on the EMU's etc... and several warnings in CV.
Should you do it live? Probably not, but there are those situations where shurring down an EVA is NOT an option.
For adding 6 shelves, i'd probably request the downtime since the shelves are likely to need an update from the controllers and it would always be better to have a downtime for it.

Re: Adding a 0C6D to and EVA
if the CAN bus extension is not installed from the beginning, then it is an offline operation (after the EVA switch off), because you need to replace the bottom terminator by the cabinet bus cable and connect it to the expansion rack (0C6D).

Re: Adding a 0C6D to and EVA
1-I won't have bottom terminator , only top terminator in both racks?
The solution is 2C12D, now 2C16D, the 0C6D not full populated (I will take care about not insert disk in slots 13, 14).
2-Can I use the free port in the loop switches to each one of the new disk enclosures?
If answer yes
3-whitch loop switches port I should use the ports of the two in the bottom or the ports of the two in the top of the main rack?
Regards
W.S

Re: Adding a 0C6D to and EVA
it is not an online operation because you are removing the bus termination...
no drives in bays 12-14 in the enclosures 16, 17, 19, 20

Re: Adding a 0C6D to and EVA
After the installation I have received 6 boxes with the following part 345580-B21.
The description say that is Cable Kit, Expansion cab Drive Shelf.
I remember that in the first EVA's generation fiber cable were use as connection from the disk enclosure to the loop switches, after they were replace by copper cables.
Is still supported?
or
they are used only for the expansion disk enclosure? (fiber cable)
