v No cable can be connected between a port on a left canister and a port on a
right canister.
v A cable must not be connected between ports in the same enclosure.
v Port 4 of a control enclosure is not cabled to another control enclosure.
v Attach cables serially between enclosures. Do not skip an enclosure.
v The last enclosure in a chain must not have cables in port 2 of canister 1 and
port 2 of canister 2.
v A connected port on the node canister must connect to a single port on an
expansion canister. Cables that split the connector out into separate physical
connections are not supported.
v Ensure that cables are installed in an orderly way to reduce the risk of cable
damage when replaceable units are removed or inserted.
v Arrange your cables to provide access to the following items:
USB ports
USB port access is required when you use a USB flash drive to configure
the system.
Enclosures
Access is required to the hardware for servicing and for safely removing
and replacing components using two or more people.
Connecting Ethernet cables to node canisters
To provide system management connectivity for your Storwize V3700 system, you
must connect Ethernet cables to Ethernet port 1 of each node canister in the control
enclosure. This connection can optionally also be used for iSCSI host connection.
Ethernet port 2 can optionally be connected to provide a second system
management address, a second iSCSI host connection, or both.
Procedure
To install the Ethernet cables, complete the following steps.
1. Connect Ethernet port 1 of each node canister in the system to the IP network
that will provide connection to the system management interfaces, as shown in
Figure 30. This port can also be used for iSCSI connectivity to the system by
hosts on the network. Where more than one control enclosure is present in the
system, ensure port 1 of every node canister is connected to the same network
to provide access if the configuration 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
