unix server failing to boot

i have unix 5.4 running on team server hs failing to boot.

when i turn it on, it prints the following lines on the screen and just stops:

module ID 01: (0011) Main power supply ok
module ID 01: (0012) checks ok
module ID 01: (0020) test of SCSI device 0 x 0 in progress
module ID 01: (0022) test of SCSI device 0 x 0 in progress
module ID 01: (0024) reading bootstrap header
module ID 01: (0029) secondary bootstrap loading

please help me i am in trouble

What OS is this? Unix 5.4 doesn't give much of a clue.

You may want to try booting from cd (if you don't tell us what OS, we can't give you specific information).

its Unix 5.4 version 7

What vendor?

Vendor - Fujitsu Icl
