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 rst 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 rst
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
rst 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.
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.
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.
Onboard Ethernet Port Speed Function
1 10 Gbps Management IP, Service IP, Host I/O
2 10 Gbps Secondary Management IP, Host I/O
3 10 Gbps Host I/O
4 10 Gbps Host I/O
T 1 Gbps Technician Port - DHCP/DNS for direct attach service management.

Connecting Ethernet cables
1. Connect Ethernet port 1 of each node canister to the IP network that will provide connection to the system management interfaces.
Ethernet port 1 can be used for iSCSI connectivity to the system by hosts on the network. If the
system has more than one control enclosure, ensure port 1 of every node canister is connected to the
same network to provide access if the conguration node fails.
2. Optionally, connect Ethernet port 2 of each node canister in the system to a second IP network that will provide redundant connection to
the system management interfaces. Port 2 can also be used for iSCSI connectivity to the system by hosts on the network. If the system
contains more than one control enclosure, ensure that port 2 of every node canister is connected to the same network to provide access
if the conguration node fails.
Connecting other networking cables
Each control enclosure has PCIe slots that support optional networking adapters. However, the location requirements for the networking
adapters differ between the FlashSystem 7200 and Storwize V7000 Gen3 control enclosures. Use the information that you entered in
Network cable worksheets on page 9 to establish the proper connections.
On FlashSystem 7200 systems, the networking adapters can be installed in any PCIe slot.
Type Adapter Ports Total Adapters Purpose
16 Gbps Fibre Channel (FC) 4 0-3 Supports NVMe over Fabrics (NVME-oF). Required for adding control enclosures, up
to a maximum of four per system.
32 Gbps FC 4 0-3 Supports simultaneous SCSI and NVMeFC connections on the same port.
25 Gbps Ethernet (iWARP) 2 0-3 Supports iSCSI or iSER host attachment.
25 Gbps Ethernet (RoCE) 2 0-3
12 Gbps SAS adapter 4 (2 active) 1 Required to connect to expansion enclosures. If ordered, this adapter is

25 Gbps Ethernet (RoCE) 2 0-2
3 12 Gbps SAS adapter 4 (2 active) 1 Required to connect to expansion enclosures. This adapter is preinstalled
in PCIe slot 3.
1. Ensure that the networking adapters are installed in the appropriate PCIe slot.
2. Connect the required number of FC or Ethernet cables to the ports on each node canister. Both node canisters must have the same
number of cables connected.
Powering on the system
After you install all hardware components, you must power on the system and check its status. Each control enclosure has two power
supply units (PSUs). To provide redundancy in a power failure, connect the power cords to separate power circuits.
Attention: Do not power on the system with any open drive bays or host interface adapter slots. Open bays or PCIe slots
disrupt the internal air flow, causing the drives to receive insufcient cooling. Filler panels must be installed in all empty
drive bays and PCIe slots.

1. Ensure that the circuit breakers or switches of the power sources are turned on.
2. Ensure that each power cable is secured to each PSU on the back of the node. To do so, route each power cable through the retainer.
The cable retainer has a curved opening that faces the rear of the PSU. After you plug the power cable in to the PSU, slip the power cable
behind the retainer. Pull the cable back into the retainer opening to secure it. Then, route each power cable through the cable retainer.
For PSU 1, hook the power cable underneath the cable retainer so the cable can extend to the left.
For PSU 2, make a loop to secure the cable under the retainer and extend the power cable to the right side of
the node.
To remove a power cable, push the cable forward to unhook it from the cable retainer. Then, unplug the cable
from the PSU.
3. Connect the PSUs of the control enclosure and each expansion enclosure to their power sources.
4. Check the status LED indicators to verify the status of the enclosure. The control enclosure is ready and running without critical errors
when the LEDs indicate the following status.
Location LEDs Indicator Status

Setting up the system or adding the control enclosure to an existing system
The system can contain 1-4 control enclosures. If you are adding a control enclosure to an existing system, go to Adding a control enclosure
to an existing system on page 8. Otherwise, continue to Setting up the system on page 7.
Setting up the system
Each node canister in the control enclosure has a 1 Gbps Ethernet technician port. Before you initiate a new system, you must connect an
Ethernet cable to the technician port on the control enclosure.
1. Locate the technician ports on the control enclosure. Because node canister 1 is inverted, the plug of the Ethernet cable also needs to be
inverted to connect to the technician port.
2. Connect an Ethernet cable to a technician port. The cable must be long enough to connect easily to a notebook computer.
If Dynamic Host Conguration Protocol (DHCP) is available, the notebook computer is automatcially congured. If DHCP is not available,
use the following information to congure the computer.
Static IPv4 Address Subnet Mask Gateway DNS
192.168.0.2 255.255.255.0 192.168.0.1 192.168.0.1
3. Use the notebook computer to open a new web browser page. The web browser might display a warning about a potential security risk.
It is safe to accept the risk and continue. See Browser considerations on page 8 for more information.
4. If the node canisters communicate with each other using RDMA over Ethernet, browse to address http://service or press the
wrench icon on the initialization page to access the Service Assistant Tool. Use the following credentials to sign in to the system.
User ID Initial Password
superuser passw0rd
5. Use the Change node IP tab of the Service Assistant to congure the node IP settings for the node. Repeat this step for each node
canister in the system.
6. Use the initialization GUI to enter the requested information, such as the management IP address and service IP addresses.
You need to set the IP address, subnet mask, and DNS server only when you do not want to use
DHCP.
For more information, see Management and service address worksheet on page 11.
7
Adding a control enclosure to an existing system
If the system was already set up on another control enclosure, do not install it again on this control enclosure. Instead, use the management
GUI to add the control enclosure to the system.
1. Connect the node canisters to the storage area network or to a 25 Gbps (or faster) Ethernet.
2. Congure the zoning on the SAN switches. The correct zoning provides a way for the FC ports to connect to each other.
If the new node canisters use RDMA over Ethernet to communicate with other node canisters, use the service assistant tool or the
satask chnodeip command to set the node IP of each node that will be in the system.
3. In the management GUI, select Monitoring > System. On the System - Overview page, select Add Enclosure.
When a new enclosure is cabled correctly to the system, this action automatically displays on the System - Overview page. If this action
does not appear, ensure that the new enclosure is cabled correctly. You can also add a new enclosure by selecting Add Enclosure from
the System Actions menu.
4. Complete the instructions in the Add Enclosure wizard until the control enclosure is added to the system.
5. If two control enclosures are in the system, you must set up a quorum disk or application outside of the system. If the two control
enclosures lose communication with each other, the quorum disk prevents both I/O groups from going offline.
Browser considerations
The management GUI supports the following HTML5-compliant browsers. Certain features must be enabled on the browser. Review the
documentation that is provided with your browser to determine how to enable each item.
Browser Required enabled features
• Mozilla Firefox 80.0.1
• Mozilla Firefox Extended Support Release (ESR) 78.2.0
• Microsoft Edge 85.0
• Google Chrome 85.0
• JavaScript
• Cookies
• Scripts allowed to disable or replace context menus (Mozilla Firefox
only)
In addition, review the following considerations about browser security features and certicates.
• Browser security features might prompt you before the browser accepts the self-signed certicate that the system issues.
• You might need to remove old certicates that are stored in the browser before the browser accepts the request.
• The web browser might display a warning about a potential security risk. It is safe to accept the risk and continue.
• After the technician port physical connection is completed (that is, connected both ends), it can take up to 45 seconds before the port is
fully up and able to process requests. Submitting requests before this interval might result in 404 error responses.
• If the http://service request causes a 404 error or does not produce a response, you might need to use URL https://
192.168.0.1 to connect to the system.
Installation worksheets
Worksheets can help you plan and install the system. You can also use the worksheets to track important information as you remove and
reinstall parts from the control enclosure during the installation process.
