devices using common grounding, make sure that grounding resistance is 10
ohms or less. Be sure to have the facility administrator or a certified electrician
confirm the grounding method for the building and perform the grounding work.
Also, do not connect to the IT power distribution system of a power supply facility
where the neutral phase of three phases is not grounded. Otherwise, equipment
may malfunction or be damaged.

Checking External Interface Port
Specifications
This section provides an overview of the specifications of the external interface ports
required for installation and operation of the SPARC M12-1.
You can use the following external interface ports on the SPARC M12-1.
XSCF unit administration port
Serial port
■
The eXtended System Control Facility (XSCF) has one RS-232C-compliant serial
port. You can monitor and control the system by connecting the system
management terminal to the serial port. Functions that require TCP/IP are not
available through the serial port.
XSCF-LAN port
■
In addition to the serial port, the XSCF has two 1000BASE-T LAN ports. You can
remotely monitor and control the system by configuring a system control network
using a LAN port. There are two types of interfaces available: a command-line
interface (XSCF shell) and a browser user interface (XSCF Web).
The XSCF-LAN ports support auto-negotiation only. Therefore, the communication
speed/mode for the XSCF-LAN ports cannot be configured.
Do not make a connection with a network switch or hub until you complete the
network setting for the XSCF. If a connection is made before the completion of the
setting, devices connecting with others may become unable to communicate, or
unauthorized login by a malicious third party to the XSCF of this chassis may be
unable to be prevented.
XSCF USB port (for field engineers)
■
Field engineers use this port to download information from the XSCF.
Other unit ports
10 GbE LAN port
■
The port is used to connect Oracle Solaris to the network. There are four ports.
Connection to the network is also possible through a LAN card, which is provided
by the customer, mounted in a PCI Express (PCIe) slot.
