Installation Guidelines
NOTE:
Do not remove the dismantlement-preventive seal on PFC without
permission. If you want to dismantle it, you should contact the local
agent of H3C for permission. Otherwise, H3C shall not be held liable
for any consequence caused thereby.
To avoid any device impairment and bodily injury caused by improper use,
observe these rules:
•
Wear an ESD wrist strap (not provided with the device) and ensure a
good skin contact.
•
Keep the PFC away from high-power radio transmitters, radars, and
high-frequency heavy-current devices. Use electromagnetic shielding
when necessary.
•
Ensure good ventilation and heat dissipation for the PFC.
•
Place no objects on the PFC to avoid damage to the PFC or impact to
dissipation efficiency.
•
To stack PFCs, keep a vertical distance of 1.5 cm (0.59 in) between
devices for the sake of ventilation and heat dissipation.
