Changing Switch Settings - NEC Express5800/180Rb-7 User Manual

Changing Switch Settings

Before doing the procedures in this section, make sure that
your system is powered off and unplug the AC power cords
from the back of the chassis. Failure to disconnect power
before setting the switches can result in personal injury and
equipment damage.
Observe static precautions. Use an antistatic wrist strap.
To set the system configuration switches on the I/O carrier board:
1. Observe the safety and ESD precautions at the beginning of Chapter 4.
2. Turn off all connected peripherals and turn off system power.
3. Remove the PCI hot-plug cover. You do not need to remove the I/O carrier
from the chassis. Due to the location of the switch block, an add-in card
populated in slot 3 may have to be removed.
4. Refer to Figure 3-6 for Switch SW4G1 location. In the figure, the switch is
located to the left and slightly below the PCI Slot number 3 on the I/O
board. When you are looking at the actual system, the board will be turned
90 degrees, and the switch will be located to the right and slightly below PCI
Slot number 3 on the I/O board. A diagram of the switch configuration is
also located on the underside of the PCI hot-plug cover.
5. The switch block is shown with all switches in the open or disabled position
by default.
6. Move the individual switch for the desired setting.
7. Power on the system for the change to take effect.
8. Return the switch to its' default position after the desired operation is
complete.
