2-7
Board-level tests
Each of the ESU 120e boards contains an on- board processor which
executes a series of tests checking the circuitry on the board.
• RAM and EPROM tests.
• Verify on-board circuitry.
Unit-level tests
• Front panel LED verification.
• Board-to-board interface test. A test pattern is sent from the
controller through a loopback on all other boards and checked
on the controller. This verifies the data path, clocks, and control
signals for the entire chassis.
Initialization
Set User Passcode
The ESU 120e is designed to operate with or without the use of a
passcode. The default condition is without a passcode.
If the unit is to be remotely accessed using T-Watch PRO you
must enter a passcode. When managing a number of units, the
passcode can be the same for all the units.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation other than
viewing. See Set Passcode on page 6-2 for details.
Set Unit Identification
The Unit ID sets the unit to respond to remote control (controlled
by a device other than the front panel or terminal). If no Unit ID is
recorded it is not possible to operate from any remote control
device, including the local PC for T-Watch PRO or SNMP. See Unit
ID on page 6-4 for details.
