Connecting Ethernet cables to node canisters

The control enclosures on Storwize V5000 Gen2 systems have several Ethernet
ports on the rear of each node canister. The ports provide access to system
management facilities and can also provide iSCSI connectivity. The number of
ports and their initial function differ across each of the Storwize V5000 Gen2
systems.
Procedure
To install the Ethernet cables, complete the following steps.
1. If you have a Storwize V5010 or Storwize V5020 system, complete the following

steps.
a. Identify the location and function of the Ethernet ports on your system;
refer to Figure 22 on page 31 and Figure 23 on page 31.
v Port 1 can be used to provide Ethernet connections; in the figures, port 1
is identified by the green cable.
v Port 2 serves as the technician port when the system is initially set up or
when service is needed. In the figures, port 2 is identified by the blue
cable. After the system initializes, port 2 can also be used for iSCSI
connectivity or IP replication.
Note: Do not connect port 2 to a network switch until the system
initialization or service is complete. After the system initializes, the
technician port is automatically disabled and port 2 can be used for
Ethernet connectivity. However, when port 2 is used to perform system
service, you must first enter the satask chserviceip -techport disable
command to disable the technician port. You can then use port 2 to
provide additional Ethernet connectivity.
b. Connect Ethernet port 1 of each node canister in the system to the IP
network that will provide a connection to the system management
interfaces.
Figure 22 on page 31 shows the Ethernet cabling and the ports on the back
of a Storwize V5010 system.
