Over Temperature Blink Pattern

An over temperature blink pattern is 5 blinks followed by a two second pause. The
5-blink error pattern indicates that the air temperature inside the switch has
exceeded the failure temperature threshold. The failure temperature threshold is
70° C.
If the Heartbeat LED shows the over temperature blink pattern, do the following:
1. Inspect the chassis vents. Are the intake and exhaust vents clear?
2. Inspect the Power Supply Fault LED on both power supplies. Is the Power
Supply Fault LED illuminated on either power supply?

Establish communications with the switch using Telnet. Enter one of
the following on the command line:
telnet xxx.xxx.xxx.xxx
or
telnet switchname
where xxx.xxx.xxx.xxx is the switch IP address and switchname is the
switch name associated with the IP address.
A Telnet window opens prompting you for a login. Enter an account
name and password. The default account name and password are
(admin, password).
Open an admin session to acquire the necessary authority.
