Secure telnet access is available using Secure Shell (SSH), a network security protocol for secure
remote login and other secure network services over an insecure network.
Brocade Web Tools management is available via a secure browser using Secure Sockets Layer (SSL).
The SSL security protocol provides data encryption, server authentication, message integrity, and
optional client authentication for a TCP/IP connection. Because SSL is built into all major browsers and
Web servers, installing a digital certificate enables the SSL capabilities.
Interpreting POST Results
The power-on self test (POST) system check is performed each time the switch is powered on, rebooted,
or reset.
Example POSTOutput
During POST, the LEDs are activated in various indicator patterns.

To determine POST completion status:

•Verify that the LEDs on the switch indicate a healthy SilkWorm 4016. LED patterns are described
in “Interpreting LED Activity,” next.
If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon. Use
the switchShow command or Web Tools to verify the LED state. For information about how to turn
beaconing on and off, see the Fabric OS Administrator’s Guide or the Web Tools Administrator’s
Guide.
•Use the blade server chassis’ management module to verify that the switch is working correctly.
Refer to the blade server chassis documentation for details.
•Review the system log for errors.
Any errors detected during POST are written to the system log. Access this log through the
errShow command. For information about this command, see the Fabric OS Command Reference
Manual. For information about error messages, see the Fabric OS System Error Message Reference
Manual.
