Step 2: Update PROM1 and/or PROM2
:
Now you can use the field update utility (epcs) to program the EPCS PROMs. This is a custom utility that resides in the unit.
Warning:
Care should be taken at this time, if miss spelled characters or letters are typed by accident, or you have missed
to type the bin command in Step 1, this could cause the unit's Flash memory to be corrupted. The unit will try to reload
the OS using the corrupted file ten (10) times before it displays the following screen. You can recover from this situation by
repeating the procedure all over again from Step 1 above.
FIGURE 6.14
Ready: Please read the rest of this page once before typing the commands.
Update FPGA1 by programming EPCS1:
epcs –e1 EPCS_1_ver#.bin
Update FPGA2 by programming EPCS2: (if necessary)
epcs –e2 EPCS_2_ver#.bin
NOTE:
Both EPCS PROMS can be programmed concurrently using two different terminal
sessions (logins). If you get errors during programming then
DO NOT TURN OFF THE
UNIT,
just repeat the epcs commands again.
The server board should now configure itself on power-up.
Two choices to reset the unit:
(1)
Unplug and reconnect power cable in the back of the unit.
(2)
Use Telnet and type “epcs –c” this will automatically reboot the unit without a need for resetting with power connector.
You can save your configurations so it’s very quick and easy to telnet into the board again.
After you telnet into the server board you must login into the unit with the following credentials:
Username =
Admin
(case-sensitive)
Password =
pass
(case-sensitive)
Then cd to the /home/ftp directory where the EPCS_x.bin files have been placed.
cd home/ftp
