Grounding requirements
Ground each chassis appropriately according to the input power type.
For single-phase input
■
The components of each chassis do not include a grounded (three-wire type)
power cord. Order the power cords that match the device. Always connect the
power cords to grounded power outlets.
To confirm the type of power supplied by the building, contact the facility
administrator or a certified electrician.
For three-phase input
■
No power cord is supplied for three-phase input. Grounded power cords must be
connected from the distribution panel directly to the terminal boards of power
supply chassis as part of local electrical work.
Although common grounding is possible with this device, grounding methods
vary depending on the building of the installation. When using common
grounding, ground devices such that the grounding resistance is equal to or less
than 10 ohms. 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 in installation and operation of the SPARC M10-1.
You can use the following external interface ports on the SPARC M10-1.
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).
