## 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: 

GLYPH<SM590000> 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. 

GLYPH<SM590000> 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. 

GLYPH<SM590000> When you forget 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 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.
