Lockout and tagout

For maximum safety while power is applied, always perform a lockout and tagout procedure. Remove
power from the entire test system and discharge capacitors before connecting or disconnecting
cables or any instrument, including the device under test. When you perform lockout and tagout
procedures, make sure that you note all warning labels on the cabinet and instruments (see the
following figure).
Severe personal injury or death due to electric shock or electrocution may result if power is
not removed before working inside the cabinet. Always perform the lockout and tagout
procedure before opening the system cabinet. Also, never turn on the system until all
connections and safety grounds are installed.
To remove system power:
1. You must shut down the software and remove all power from the computer and the system (see

PDU is at the back of the cabinet below the rear door.
