664 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
USB ports
Each node canister has one USB port. The location of the port is the same on every model,
and no indicators are associated with it.
Figure 12-2 shows the location of the USB port.

The USB flash drive is not required to initialize the system configuration. However, it can be
used for other functions. Using the USB flash drive is required in the following situations:
When you cannot connect to a node canister in a control enclosure by using the service
assistant or the technician port, and you want to see the status of the node or re-enable
the technician port.
When you do not know, or cannot use, the service IP address for the node canister in the
control enclosure and must set the address.
When you have forgotten the superuser password and must reset the password.
Ethernet ports
The Storwize V5010 and Storwize V5020 node canisters have two 100/1000 Mbps Ethernet
ports. Both ports can be used for management, Internet Small Computer System Interface
(iSCSI) traffic, and Internet Protocol (IP) replication. Additionally, port 2 can be used as a
technician port (the white box with “T” in the center of the box) for system initialization and
servicing. After initialization the technician port will be disabled. It is possible to reactivate the
technician port later again via CLI commands.
Figure 12-3 shows the Ethernet ports on the Storwize V5010.
