CAUTION:
An electrostatic discharge wrist strap with a minimum
resistance of 250K Ohms should be worn when handling
Series 5 circuit packs to prevent possible damage to the
circuit packs. Before using the wrist strap, check it for
opens, shorts, and minimum resistance value. If the strap
does not pass these checks it should not be used. To avoid
possible personal injury while using the wrist strap, do not
connect it to the power shelf or adjacent portions of the RT
frame. Connect the wrist strap to ESD GRD jack on the fan
unit, if present. If grounding jack is not present, connect
wrist strap to bare-metal section of the frame well away from
the power shelf.
