1.5.3 Using Safe Mode
Use the recessed Safe Mode button on the reader
connector panel to recover from errors which prevent
the reader from operating in normal mode. In Safe
Mode the reader is configured with a static IP address
of 10.0.0.101. Safe mode operation restores factory
default settings as follows:
Firmware Version:
IP Address:
Host Name:
Although the browser-based interface pages are
displayed in red when operating in safe mode, the
reader is still functional, although it cannot read or
write tags. In most cases, the reader will need to be
reconfigured for operation with the reader application
after starting in Safe Mode.
1. 1. With the reader running, hold down the
recessed reset button for 4 seconds, using a non-
conductive object.
2. Release the button
3. The green LED should turn solid as soon as the
button is released, indicating the reader is
rebooting. It should take approximately 30
seconds to boot into Safe Mode. The web server,
telnet server and SSH server run in Safe Mode,
however none of the RFID features are activated.
To communicate with the reader in Safe Mode, a
PC must have an IP address and subnet mask
that are compatible with the reader settings, for
example:
IP address 10.0.0.10
netmask 255.255.255.0
There are two main reasons to enter Safe Mode.
One is to perform a firmware update to repair a
corrupted file system. The second is to change
settings that are preventing the reader from
operating normally.
Both of these tasks can be performed via the web
interface.
