Main Power Status : Up
Redundant Power Status : Up
Configuration notes
There are several cautions and warnings that you should pay attention to when installing or
replacing power supplies. Refer to the Brocade BR6910 Installation Guide for more information.
Common diagnostic scenarios
• Power supply is not providing power - check all power connections, and replace faulty power
supply if necessary. See the Bro a dc om BR6910 Installation Guide for more information.
• Temperature is outside normal operating range. See the following section.
What to do if the temperature is outside normal operating range
If the device detects temperatures outside the normal range, depending on the severity of the
reading, it will automatically do one of the following:
• Leave the fan speed as is.
• Increase the fan speed.
• Decrease the fan speed.
• Generate a Syslog message and an SNMP trap.
If none of these measures resolves the problem, you should perform the following steps:
1. Shut down the device immediately.
2. Inspect all fans for damage or failure.
3. Inspect electrical connections to the fans.
4. Contact technical support at Brocade for assistance.
The normal operating temperature, humidity, and altitude specifications for Bro a dc om 6910
Switch are:
• Operating Temperature: -40° – 149° F (-40° – 65° C).
• Relative Humidity: 5 to 90%, @ 149° F (65° C), non-condensing.
• Operating Altitude: 0 – 10,000 ft (0 – 3048 meters).
Fiber-optic modules
The most common problems with fiber-optic modules are caused by dirty connectors. Optical
cables that are contaminated in any way (with dust, hand oil, and so on) can degrade the optic eye
pattern. Some of the following symptoms may be experienced:
• Port appears not to function (either no link or unstable link)
• Cyclic redundancy check (CRC) errors
• Port flapping
