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.
NOTE:
The term "facility shelf" is used throughout this procedure to
refer to the middle shelf of the Series 5 RT. The remaining
shelves will be referenced according to digroup name (e.g.,
AB shelf contains digroups A and B). White system refers to
the two upper shelves of the Series 5 RT plus the right half of
the facility shelf and blue system refers to the two lower
shelves of the Series 5 RT plus the left half of the facility
shelf.
Install (if not previously installed) RSU (ring switch unit) in bulk
power shelf.
