USB ports Ethernet 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: 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 is disabled. It is possible to reactivate the  technician port later again by using CLI commands.  Figure 12-3 shows the Ethernet ports on the Storwize V5010. 626  Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.2.1 Figure 12-3 Storwize V5010 Ethernet ports Figure 12-2 Node canister USB port (the Storwize V5020) GLYPH<SM590000> When you forget the superuser password and must reset the password.
