Installing FRUs
There is no required order for installing FRUs. HP recommends that you connect power cables after
completing installing all required FRUs.
TIP:
Keep the chassis and the component packages for future use.
Attaching an ESD-preventive wrist strap
Every HP FlexFabric 12900 switch provides an ESD-preventive wrist strap. To minimize ESD damage to
electronic components, wear the ESD-preventive wrist strap and make sure it is well grounded when
installing modules.
To use an ESD-preventive wrist strap:
1.
Make sure the switch is well grounded. For how to ground your switch, see "
2.
Put on the wrist strap.
3.
Tighten the wrist strap to keep good skin contact. Make sure the resistance reading between your
body and the ground is between 1 and 10 megohms.
4.
As shown in
, insert the ESD-preventive wrist strap into an ESD port (one on the front
panel and one on the rear panel) on the switch chassis, or attach it to the grounding screw of the
chassis with an alligator clip.
