Note
If you are only recovering one access point, you can enter
00:10:40:FF:FF:FF. This special MAC address works with all access
points.
2. Type this command to continuously ping the access point while you
boot the access point.
ping –t –l 100 IPaddress
where IPaddress is the access point IP address you assigned in Step
1.
3. Disconnect and reconnect the power cable (or Ethernet cable, if you
are using power over Ethernet) to the access point. The access point
has no On/Off switch, so it boots as soon as you apply power.
4. When the access point responds to the ping, use any TFTP client to
transfer AP824X.DNL file to the access point. Make sure the Transfer
mode is binary.
tftp –i IPaddress put AP824X.dnl
where IPaddress is the access point IP address you assigned in Step
1.
Once the TFTP transfer is complete, the access point will begin
booting the image that was just passed to it. This image is only
resident in RAM. If you reboot the access point or if the access point
loses power, the AP824X.DNL image will be lost.
5. Type this command to remove the static ARP cache entry from your
PC.
arp –d IPaddress
where IPaddress is the access point IP address you assigned in Step
1.
When the access point is done booting, all access point services are
available. You can now telnet to the access point to upgrade it with a
permanent image and configure it.
Note
You may be unable to access the web browser interface if the
support files for this interface still need to be recovered. If so, use
telnet to upgrade the access point, and then use the web browser
interface to configure it.
