Precautions

Maintain the firewall hardware under the guidance of the local dealer or technical support
engineers appointed by H3C.
To avoid injuries, disconnect all power sources from the firewall before maintaining any hardware
modules of the firewall.
Always wear an ESD-preventive wrist strap or ESD-preventive gloves when maintaining the
firewall hardware. For more information, refer to the section talking about electrostatic discharge
prevention in Chapter 3 "Preparing for Installation."
When installing or removing a demountable module, such as an MPU, an LPU, a memory module,
or a CF card, ensure good alignment with the slot and use uniform force to avoid damage to the
module.
Put the removed MPU, LPU, memory module, or CF card on an antistatic workbench with the PCB
side facing upward or place it in antistatic bags.
When checking or moving a removed MPU, LPU, memory module, or CF card, avoid touching any
components on the PCB.
