Setting the Locally Administered MAC Address (LAA)
Network Administrator Tip
Each printer comes with a unique, pre-assigned MAC address printed on the NIC
faceplate and set 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
use the factory-set MAC address. Also, this feature is only used with Token Ring.
Note: Before using the procedure described in this section, refer to “Using the
Operator Panel Keys to Set Network Addresses” on page 202.
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 ETHERNET MENU (or
TOKEN RING MENU).
3. Press the Item key until the operator panel displays the following:
TOKEN RING MENU
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 ð1<
ð4-AC-9A-ðð-ðð
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).
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:
ð4<AC-9A-ðð-ðð
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 ð1-
ð4-9A-ð1-ð2-ð2 \
9. Press the Online button to display the Ready message. The panel displays the
message I/O Initializing and the new addresses are written to non-volatile
memory. (This is where the addresses are stored. Non-volatile memory maintains
information when the printer is powered off.) This process takes a few minutes, do
not power off the printer while the message I/O Initializing is displayed.
