Installing FRUs

Keep the chassis and the component packages for future use.
CAUTION:
• To ensure good ventilation, install filler panels on unused slots.
• As a best practice, connect power cords after installing all required FRUs.
TIP:
Long-time exposure to strong air flow might cause discomfort. To avoid this hazard, do not stand
close to the air outlet vents while the device is operating. If you must be next to the device on the air
outlet vent side for an extended period, avoid the air flow or take other protective measures.

Attaching an ESD wrist strap

The device is provided with an ESD wrist strap. To minimize ESD damage to electronic components,
wear the ESD wrist strap and make sure it is reliably grounded before you install FRUs.
To attach an ESD wrist strap:
1. Make sure the device is reliably grounded. For information about how to ground your device,
see "Installing the device."
2. Put on the wrist strap.
3. Tighten the wrist strap to make sure it makes good skin contact. Make sure the resistance
reading between your body and the ground is between 1 and 10 megohms.
4. As shown in Figure 3-1, insert the ESD wrist strap into the ESD jack on the chassis.
