Grass Valley FT Server - Manual (Page 29)

2. Once the system has booted up, the GV logo should be displayed on the screen of the display
unit. While the GV logo is displayed on the screen, the FT server is performing a power-on self
test (POST) to check the unit. Upon the completion of POST, the OS will start.
If the server finds errors during POST (power up self test), it will interrupt POST and display an
error message.
CPU/IO module status
The CPU/IO module (0 or 1) that is started first is managed as the primary, and the module started
later is managed as the secondary. If one CPU/IO module is disconnected because of a failure, the
other module becomes the primary.
The CPU/IO module to be started first is selected depending on the primary/secondary status of
modules when the server was shut down the last time.
The following devices are connected to the primary CPU/IO module by the connectors on the system
backplane and access both CPU/IO modules 0 and 1. When one CPU/IO module is disconnected
because of a failure, those are switched to the other module automatically and continue operating.
• VGA (display)
• USB device (keyboard, mouse, optical disk drive)
NOTE: Both CPU/IO modules 0 and 1 can access the optical disk drive. If one CPU/IO module
is isolated because of a failure, only the active (Primary) CPU/IO module can access the drive.
NOTE: The drive letter of the optical disk drive is reallocated automatically. The unused letter
is allocated to the drive in the order of D to Z. If you want to set the fixed drive letter to the optical
disk drive, specify the letter which is not allocated in the order of D to Z after setting the hard
disk drive letter.
