External Interfaces - Fujitsu SPARC Enterprise M4000 User Manual

Note – (2) Only the system model with a special interface can power on and off the
peripheral devices. (See Remote Cabinet Interface (RCI) in
Redundant XSCFs (High-End Systems Only)
The high-end systems use a redundant configuration of XSCF Units, thereby
providing a high-reliability with the system. The XSCF that controls the server is
called the Active XSCF or Active XSCF Unit, while the other XSCF acts as a backup
and is called the Standby XSCF or Standby XSCF Unit. The Active XSCF and the
Standby XSCF monitor each other, and if an error is detected, they determine when
a failover switching to Active or Standby should be performed.

External Interfaces

The following connectors (ports) and LEDs act as the external interface of the XSCF
Unit. The user, system administrator, and field engineer (FE) can use these ports for
server monitoring and XSCF firmware operations:
One Serial port that can be used for the command line interface (CLI) (Note 1)
■
Two Ethernet ports (XSCF-LAN ports) (10/100BASE-T)
■
CLI and the browser user interface (BUI) can be used with these ports for server
monitoring and operations. (Note 1)
USB port that an FE or a system administrator can use to download hardware
■
information
Two Uninterruptible Power Control (UPC) ports to connect the entire system with
■
an Uninterruptible Power Supply Unit (UPS) (Note 2)
Remote Cabinet Interface (RCI) port to perform power supply interlock by
■
connecting a system and an I/O device with a RCI device (Note 3)
Three LEDs (ACTIVE LED, READY LED, and CHECK LED) that indicate the
■
XSCF Unit status
Note – (1) In this manual, XSCF CLI functions are called "XSCF Shell," and XSCF
BUI functions are called "XSCF Web."
Note – (2) An uninterruptible power supply unit is connected for backup power
control purposes in the event of a power outage. In the high-end system, the UPC
interface ports are in the cabinet.
