M204 SPECIFICATIONS: Hardware Specifications 173

An invalid license mask and key forces the M204 into license-

violation mode after three minutes of operation. Make sure the

S3 jumper is on EEPROM Enable and if it continues, check to see

if the keys are enabled. Please see list key on page 86. A reboot

will temporarily ﬁx this.

Unrecoverable errors detected by the M204 ﬁrmware force the

Print Server into Firmware Panic mode. Manually reset the M204

to resume normal operation.

The watchdog timer is a hardware device that resets the system if

not serviced regularly by the CPU. The purpose of the watchdog

is to prevent the CPU from entering an inﬁnite loop because of

some hardware or ﬁrmware problem. After a watchdog interrupt,

some diagnostic information is saved for debugging and the

M204 resumes operation in Auto-Reset Mode. The M204 will

auto-reset up to 16 times before entering non-operational Watch-

dog Halt.

Unsupported interrupts force the M204 into this non-operational

mode and typically indicate a hardware problem.
