You can use the technician port to do these
tasks:
On Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP systems, the second onboard Ethernet port (port 2) is used as the technician port. Lenovo Storage V3700 V2 technician port and Lenovo Storage V3700 V2 XP technician port show the location of the technician port (T) on each model.

Storage V3700 V2 XP technician port
Note: Do not connect the technician port on
a Lenovo Storage V3700 V2 or Lenovo
Storage V3700 V2 XP system to a network switch until the system initialization or service
is complete. When the technician port is disabled, you can use port
2 to provide extra Ethernet connectivity for system management, iSCSI,
or IP replication. After the system initialization completes, the
technician port is automatically disabled. However, after you complete
the service tasks, you must use the satask chserviceip -techport
disable command to disable the technician port. If you need
to service the system later, you can enable port 2 to become the technician
port again. To do so, use the service IP to enter the satask
chserviceip -techport enable -force CLI command. If you
do not have SSH access to the service IP, you must use a USB stick
to run this command in an satask.txt file. For
more information, see Procedure: Getting node canister and system information by using a USB flash drive.
Lenovo Storage V5030 and Lenovo Storage V5030F systems have a dedicated technician port. Lenovo Storage V5030 and Lenovo Storage V5030F technician port shows the location of the port (T).

Note: Never use the technician port (T) on a Lenovo Storage V5030 or Lenovo Storage V5030F system to provide an Ethernet connection to the system. Do
not connect the Ethernet technician port to a network switch. The
technician port must be directly connected to a personal computer
only when you are initializing a system or servicing a node.
