SERVMANAGERS
If any of these errors occur, it means that either the RS-232 cable is bad, the
file-transfer parameters aren’t set correctly, the transmit or receive level is
bad, or the computer or ServSwitch has a hardware problem.
NOTE
Normally only two wires are necessary to the ServManager, receive and
ground. However, if you are using DOS to copy the configuration file to
the ServManager, DOS
must see a high DSR signal input (Pin 6 on PC
COM ports, whether they are DE9 or DB25 type) in order for the copy
command to work. The ServManager provides this signal using RTS (Pin
6) output from its RS-232 Port.
Hit ENTER to continue and you should get the following message.
You can hit the up- or down-arrow to change the “Yes” to “No.” If you enter
“Yes,” you go back to the beginning of the receive-file procedure. If you enter
“No,” the ServManager proceeds with its normal power-up operation.
If verifying fails, you will get the following message:
At this point you can either hit ENTER and try again or turn OFF the
ServManager and start over. (Make sure that what you are trying to load is the
actual updated firmware program itself, and not an archived or compressed
version of it.) Depending on what was loaded, it is possible that the
ServManager’s kernel (flash loading utility), program, or configuration data is
corrupt. If you continue to get this error, then either the program file or
configuration data is corrupt, or there is a kernel, flash-memory, or other
software or hardware problem in the box; call Black Box for technical
support.
