Power-On-Self-Test (POST)
PROM Checksum Failure (1 Blink)
The Switch is not operable. This is a checksum test of the PROM designed to
verify the integrity of the PROM data. A failure indicates the PROM data is
corrupted and blinks the Heartbeat LED once between three-second pauses. No
port Logged-in LEDs blink.

port Logged-in LEDs blink.
RAM Failure (2 Blinks)
The Switch is not operable. This is a test designed to verify the data and address
busses to the SRAM as well as the SRAM integrity. A failure indicates that either
the data bus, address bus, or SRAM is failing and blinks the Heartbeat LED twice
between three-second pauses. No port Logged-in LEDs blink.

Flash Checksum Failure/Switch Management Port (Ethernet) Tests Good (3 Blinks)
The Switch is not operable except to load new Flash code. 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 section of this 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 that indicates that the processor is running out of PROM instead
of Flash memory. This is due to the Force PROM Mode switch being in the ON
position. You should never see this error in the field. The Heartbeat LED will
blink five times between three-second pauses. Refer to the Flash Pass switch in
the Chassis Switch Panel paragraphs in Section 1 of this manual.

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
functionality of each Switch ASIC. This includes the control port interface and all
