z
Replace the hardware of the V100-E only when necessary and under the guidance of technical
engineers.
z
Do not remove the H3C tamper-proof seal on the chassis cover of the device without permission. If
you want to open the chassis, contact your sales agent for permission. Otherwise, H3C shall not be
held liable for any consequence caused thereby.
z
Make sure that all power supplies have been disconnected from the V100-E before performing
hardware maintenance on it. Otherwise, you may get injured through an electric shock and the
device may be damaged.
z
Always wear an ESD-preventive strap and ensure a good skin contact when maintaining the device
hardware.
z
Use the memory module provided by H3C only. The device may not be compatible with other
memories.
Installing and Removing a DDR SDRAM
The V100-E is equipped with three types of storage devices:
z
DDR SDRAM: Stores the running programs
z
Flash memory: Stores the programs and configuration files of the V100-E
z
Boot ROM: Stores the boot and initialization programs of the V100-E
Hardware maintenance mainly involves replacing the DDR SDRAM.
Figure 6-2 presents the procedure of replacing a memory module.
