8. Completely power down the MSA array by removing the power cords on the back of the controller enclosure.
9. If you have expansion drive enclosures that are connected to the MSA controller enclosure, power them down by pressing the power
switches at the back of each drive enclosure to the Off (O) position.
Note
If the power supplies do not have power switches, remove the power cord.
Remove and replace the controllers and enclosure
1. If expansion enclosures are connected to the controller enclosure, label and remove the mini-SAS expansion cable from each controller
SAS OUT port (see Figures 7, 8, 9, 10, or 11 for the controller). If more than one expansion enclosure is connected in series, the
remaining SAS cables from these expansion enclosures can remain connected to each other.
2. Remove labeled host connect cables. SAS cables will need to be replaced due to the change of the SAS connector type on the MSA 1040
or 2040/2042 controllers.
3. Remove labeled Ethernet cables from the MSA management ports on each controller.
Important
If you are replacing the HPE P2000 G3 MSA storage enclosure, remove and label each drive from the existing enclosure for re-insertion in
the new MSA storage enclosure into the same slots if possible. The same drive order is recommended to maintain consistency with the
original layout and any documentation that might exist. However, it is not required because the metadata with be identified by the MSA
1040/2040/2042 controllers. Replace the enclosure and re-insert the drives into the new MSA storage enclosure.
4. If you upgrade to the MSA 2040/2042 controllers and do not replace the P2000 G3 MSA storage enclosure, remove the existing
controllers from the array head.
5. Follow the steps found on the HPE Product Recycling page for proper disposal of controllers.
6. Insert the new HPE MSA 2040/2042 controllers into the storage enclosure and tighten the thumb screws.
7. Insert SFPs into the MSA 2040/2042 SAN controllers. If you are planning to use DAC cables for iSCSI, then no SFPs are required. MSA
2040/2042 SAS controllers do not require SFPs. MSA 1040 controllers have SFPs pre-installed; remove 10Gb iSCSI SFPs if you will be
using DACs with the MSA 1040 controllers.
8. Reconnect or install new host connect cables. You must already have the correct SFPs or SAS cables for the MSA 2040 and DACs for
either the MSA 1040 or MSA 2040 available for installation. See Table 5.
