2. Lower the handle and slide the drive out of the enclosure as shown.
3. To replace the drive, ensure that the LED indicators are at the top of the new drive.
4. Press the blue touchpoint to unlock the latching handle on the drive.
5. Slide the new drive into the node canister. Press on the drive label near the bottom of the new drive to ensure that it is fully inserted.
6. Close the handle on the drive until the latch clicks into place.
Connecting SAS cables
This task applies if you are installing one or more SAS-attached expansion enclosures. Each control enclosure can manage two chains of 2U
and 5U expansion enclosures. The system supports an intermix of 2U and 5U expansion enclosures with a total chain weight of 10 in each of
two SAS chains. For more information about expansion enclosures, see IBM Knowledge Center (https://ibm.biz/BdqxdY).
1. Using the supplied SAS cables, connect the control enclosure to the first expansion enclosure.
a. Connect SAS port 1 of the top node canister (node 1) in the control enclosure to SAS port 1 of the left expansion canister in the first
expansion enclosure.
b. Connect SAS port 1 of the bottom node canister (node 2) in the control enclosure to SAS port 1 of the right expansion canister in the
first expansion enclosure
2. To add a second expansion enclosure chain to the control enclosure, complete the following steps.
a. Connect SAS port 3 of the top node canister in the control enclosure to SAS port 1 of the left expansion canister in the second
expansion enclosure.
b. Connect SAS port 3 of the bottom node canister in the control enclosure to SAS port 1 of the right expansion canister in the second
expansion enclosure.
Connect networking cables
To provide connectivity for the system, you must connect cables to the appropriate ports on the control enclosure.
Four 10 Gbps Ethernet ports on each node canister provide system management connections and iSCSI host connectivity. The onboard 10
Gbps Ethernet ports use RJ-45 connections and operate at 1 Gbps when connected to a 1 Gbps switch. A separate technician port provides
access to initialization and service assistant functions.

Important: In the control enclosure, node canister 1 is on top and node canister
2 is on the bottom. Because the node canisters are inverted, the location of the
ports and the numbering of the ports are oriented differently on each node
canister. It is important to remember this orientation when you are installing
adapters and cables.
