Q-Logic 16HA user manual Force Prom Mode in Effect 5 Blinks

Power-On-Self-Test (POST)

Flash Checksum Failure/Switch Management Port (Ethernet) Tests Good (3 Blinks)

The Switch is not operable The Flash checksum test verifies the integrity of the Flash data. If the Flash data is corrupt, the POST next checks the Switch Management port to find out if it is functional. It does this because the Switch Management port is the load path for loading new Flash data. If the Switch Management port tests good, the Switch blinks the Heartbeat LED three times between three-second pauses. No port Logged-in LEDs blink. This means that you may load new Flash control code via the Switch Management port. Refer to the Switch Management manual for a description of how to load new Flash code.

Flash Checksum Failure/ Switch Management port (Ethernet) Failure (4 Blinks)

The Switch is not operable. The Flash checksum test verifies the integrity of the Flash data. If the Flash data is corrupt the POST next checks the Switch Management port to find out if it is functional. It does this because the Switch Management port is the load path for loading new Flash data. If the Switch Management port tests bad, the Switch blinks the Heartbeat LED four times between three-second pauses. No port Logged-in LEDs blink. This means that the Flash control code is corrupt and the Switch Management port may not operate well enough to load new Flash code.

Force PROM Mode in Effect (5 Blinks)

This is an alarm This indicates that the processor is reading the default configura- tion from PROM instead of from Flash memory. This is due to the Test Mode Switch being in the Force PROM position. You should never see this error in the field if the Test mode switch is in the proper position. The Heartbeat LED will blink five times between three-second pauses.

Switch ASIC Test Failure (6 Blinks)

The Switch is not operable. The Switch ASIC Test verifies the base functionality of each Switch ASIC. This includes the control port interface and all functions that can be performed within the confines of an individual ASIC. A failure indicates a faulty Switch ASIC and blinks the Heartbeat LED six times between three-second pauses. The Switch disables the ports associated with the bad ASIC and blinks their Logged-in LEDs. An ASIC that fails this test could affect the operation of the remaining ports.

GBIC Bypass Port Loopback Test Failure (7 Blinks)

The Switch is operable. The GBIC Bypass Port Loop-Back Test verifies (on a port- by-port basis) the ability of each Switch ASIC to loop data out through the Serdes chip on a port and back to the ASIC control port (bypassing the GBIC). A failure indicates either a faulty Switch ASIC or an ASIC to Serdes interface problem and blinks the Heartbeat LED seven times between three-second pauses. The Switch disables the failing port or ports and blinks their Logged-in LEDs. The ports whose Logged-in LEDs are not blinking have passed the test and are all usable.
