Remote Access Interfaces
The user is responsible for providing security for the I/O ports for remote access by controlling
physical access to the I/O ports. The I/O ports must be controlled because they provide access to
all user settings, user states and the display image.
The I/O ports include RS-232, GPIB and LAN.
The LAN port provides the following services, which can be selectively disabled:
http
ftp
sockets
telnet
There is also a ‘ping’ service, which presently cannot be selectively disabled. The concern here
might be that it is possible to discover IP addresses of connected instruments in order to query their
setups over the net or break into the code.
Procedure for Declassifying a Faulty Instrument
As shipped from the factory, all the E5052Bs have the following instrument-specific calibration files stored
on the hard disk drive. When replacing a hard disk drive, in order to achieve specified performance, these
files must be copied to the new hard drive. These files are located in the directory, D:\syscal.
Perform the procedure described on the E5052B User’s Guide to declassifying an E5052B if it needs to be
removed from a secure area and be returned to a secure area.
The procedure can be found on Information on Maintenance on the E5052B User’s Guide.
