To recover a failed access point
1. From a command prompt, type this command to create a static ARP
cache entry for the netloader.
arp - s x.x.x.x yy-yy-yy-yy-yy-yy
where:
x.x.x.x is the IP address that you want to assign the access point
yy-yy-yy-yy-yy-yy is the MAC address of the access point. This MAC
address is printed on a label that is on the bottom of the access
point.
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
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 the appropriate .DNL file to the access point. Make sure the
Transfer mode is binary.
tftp - i IPaddress put filename.dnl
where:
IPaddress is the access point IP address you assigned in Step
filename is the name of the appropriate .DNL file.
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 .DNL image will be lost.
5. Type this command to remove the static ARP cache entry from your
PC.
