Upgrading your Model C160 to a Model C180
Upgrading your Model C160 to a Model C180
Your upgrade kit contains a CPU board, which, when installed, upgrades
your Model C160 workstation to a Model C180 workstation.
The following sections provide step-by-step instructions for removing the
C160 CPU board and installing the C180 CPU board.
The general steps are outlined as follows. See the individual sections for
more detailed instructions.
NOTE: The following steps must be followed in the order in which they appear. Refer to the
individual sections of this guide for the actual step-by-step procedures for upgrading
the C160 to a C180.
• Determine the LAN ID of your system.
• Power off the workstation and any peripheral devices, unplug the power cords,
and disconnect any peripheral cables.
• Remove the main tray assembly.
• Remove the C160 CPU board from the main tray.
• Remove the memory boards from the C160 CPU board and reinstall them onto
the C180 CPU board.
• Install the C180 CPU board into the main tray assembly.
• Place the main tray assembly into the workstation chassis.
• Connect power cords and cables, restart the workstation, and enter the LAN ID
when prompted.

Preparing Your Workstation
Preparing Your Workstation
1Determine the workstations LAN ID by entering the following at the prompt:
/usr/sbin/lanscan
The output is similar to the following:
Hardware Station Dev Hardware Net-Interface NM Encapsulation Mjr
Path Address lu State NameUnit State ID Methods Num
2.0.2 0x08000970ECC0 0 UP lan0 UP 4 ETHER 52
After you install the new CPU board or I/O board and power on the system for
the first time, you are prompted for the LAN ID. Record the information here so
you have a record of it:
EtherLAN ID ___________________-___________________
You must supply the dash (-) between the first six digits and the last six digits.
2Power off your workstation by pressing the power button on the front panel.
When you press the power button, the workstation automatically shuts down the
operating system before it powers off the system.
3When the workstation has completed shutting down and powering off, power off
the monitor, and any peripheral devices connected to the workstation.
4Unplug the power cord of the system unit, the monitor, and any peripheral devic-
es from ac wall outlets.

5Unplug the power cord from the back of the system unit.
WARNING: To avoid electrical shock, make sure you unplug the power cable from
the wall outlet and the system unit before proceeding any further.
CAUTION: The internal components of your workstation are susceptible to mechanical and
electrostatic shock. To prevent such damage from occurring, observe the following
precauxtions during the installation procedure.
•Stand on a static-free mat
•Wearastatic-groundingwriststrap to ensure that any accumulated electrostatic charge
discharges from your body to ground. Attach the static-grounding wrist strap by fol-
lowing the instructions on the package that contains the strap. Be sure to attach one
end of the strap to the system chassis.
6Disconnect all cables, connectors, and terminators from the connectors on the
front and rear of the system.
