Setting the Locally Administered MAC Address (LAA)
Network Administrator Tip
Each token-ring network interface card comes with a unique, pre-assigned
MAC address printed on its faceplate and set at the factory. The following
procedure allows you to use locally administered addresses (LAA) instead of
the factory value. Resetting the printer to factory defaults sets the LAA back to
the MAC address. IBM recommends that you contact your network
administrator before you change the MAC address because each LAA must be
unique on the network.
To change the LAA address for the printer:
1. Press the Online key to take the printer offline.
2. Press the Menu key until the operator panel displays TOKEN RING MENU.
3. Press the Item key until the operator panel displays MAC ADDRESS.
4. Press the Enter key. For a new printer whose MAC address has not yet been
changed, the operator panel displays the unique MAC address that came with
the card, for example:
MAC ADDRESS 01< 04-AC-9A-00-00
The “<” indicates the value you can change at this point. Notice that the first
pair of values (01, in this case) is shown on the same line as “MAC ADDRESS”.
5. Press the Value key. The asterisk (*) goes away and the value is incremented
by one. The range of the address values is zero to 255 hex (that is, FF). To
decrement the value, simultaneously press the Value key and the Shift key. To
increment or decrement the value by 10, press and hold the keys.
6. Press the Value key until the desired value is displayed, then press Enter to set
the value. The “<” moves to the next value, for example:
04<AC-9A-00-00
7. Press the Value key until the desired value is displayed, then press the Enter
key.
8. Repeat step 7 until all six value pairs have been set, then press the Enter key
to set the LAA address. The value has been set if an asterisk (*) displays to the
right of the value, for example:
MAC ADDRESS 01- 04-9A-01-02-02 *
9. Press the Online key to return the printer to READY status. The panel displays
the message I/O INITIALIZING and writes the new addresses to non-volatile
memory. (This process takes a few minutes.) Do not power off the printer
while the I/O INITIALIZING message is displayed.
