Configuring System Jumpers And Switches; Before You Begin; Configuring I/O Riser Board Function Select Switches - NEC HX4500 User Manual

If you want to remotely configure the array (from a PC client); increase array
capacity online; or monitor statistics on disk and controller activity, you must
install the Global Array Manager (GAM) option provided with your RAID
subsystem. The GAM option includes diskettes and user documentation. Use of
GAM is documented in the Global Array Manager 2 Server Installation Guide.
Increasing array capacity is covered in the MORE User Guide. This user guide
covers enhancements to both the Global Array manager and RAID
Configuration Utility utilities software that implement online RAID expansion
(MORE) technology.

Configuring System Jumpers and Switches

This section describes the jumpers and switches used on the I/O riser board,
CPU base board, and system I/O board.

Before You Begin

Only a qualified technical person should perform the procedures in this section.
Note:
system boards. Modify the boards only at an ESD
workstation. Otherwise, wear an antistatic wrist strap
attached to chassis ground.
The system jumpers enable you to set specific operating parameters for your
system. A jumper is a small plastic-encased conductor (shorting plug) that slips
over two jumper pins.

Configuring I/O Riser Board Function Select Switches

The following describes how to configure and set the I/O riser board function
select switches for specific operating parameters. The function select DIP
switches configure the use of the front panel reset switch and the use of an
optional uninterruptible power supply (UPS) unit.
Before doing the procedures in this section, make sure that
your system is powered off. Unplug all AC power cords from
the back of the chassis. Failure to disconnect power before
setting switches and moving jumpers can result in personal
injury and equipment damage.
Figure 3-1 shows the DIP switches. The switches consist of a block of four
switches, accessible on the I/O panel located on the I/O riser board at the rear of
the chassis.
