Interpreting POST results

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 through 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 SAN I/O Module is powered 
on, rebooted, or reset.

During POST, the LEDs are activated in various indicator patterns.

Perform the following steps to determine POST completion status.

1. Verify that the LEDs on the SAN I/O Module indicate a healthy SAN I/O Module. LED patterns 

are described in 

 next.

If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon. 
Use the SAN I/O Module CLI 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.

2. Use the Blade Server Enclosure’s Chassis Management Controller (CMC) GUI to verify that the 

SAN I/O Module is working correctly. 

For details, refer to the Hardware Owner’s Manual for the Blade Server Enclosure.

3. Review the system log for errors.

Any errors detected during POST are written to the system log. Access this log through the 
Module’s CLI 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.
