Indicator Test Immediately upon power-up, the 1 (Power) and LPT indicators will illuminate steadily in green for several seconds. Then the LPT indicator will become dark while the 1 (Power) indicator remains steady. Irregularity of any indicator during this test indicates that there is a problem with the indicators themselves. Circuit Tests The circuit tests immediately follow the indicator test. A normal (no fault) result is signaled by three flashes of the LPT indicator and the start of normal print server operation. If any error condition is found during the circuit tests, testing will halt with the LPT indicator continuously signaling the particular error according to the following table: LPT LED Flash Pattern Error Type Steady long flashes Continuously on One long, two short flashes One long, three short flashes One long, five short flashes One long, six short flashes Firmware Reload Required DRAM Error Timer INT error Flash Protected Flash Erase/Program error LAN Controller error One long, eight short flashes One long, nine short flashes One long, fourteen short flashes Parallel Controller Error LPT Error LAN PHY error In the event of a Firmware Reload Required error at startup, proceed according to instructions given in the PS Admin User's Guide ("PS Admin Administration" section, under the heading "Upgrading the Print Server's Internal Firmware"). The PS Admin software includes a Print Test function for confirmation of print server connections and functions. This operational test can be performed after you have installed the PS Admin software and completed the PS Admin procedures for configuring the DP-301P+. See the instructions given in the PS Admin Users Guide ("Getting Started Setting up Your Print Server" section, under the heading "Testing your Print Server"). 9
