Open the chassis
Caution:
z
Do not replace the hardware unless necessary and under the guidance of support
engineers.
z
There is an anti-dismantle seal on a screw on the chassis. You must keep the seal
intact before your sales representative maintains the firewall. So you must contact
your sales representative to obtain the permission before you open the chassis. The
company is not liable for any damage or consequence resulted from users'
operation without permission.
z
Ensure that the firewall has no electricity before servicing the device to avoid bodily
injuries and device damages.
z
Wear an ESD-preventive wrist strap when servicing the device, making sure it has
good skin-contact.
z
You must use the SDRAMs provided by H3C. Otherwise, anomalies might occur to
the device.
6.3 Replacing a DDR SDRAM
Following are the storage media available for the firewall:
z
DDR SDRAM (Synchronous Dynamic RAM): where the programs of the firewall
are running.
z
Flash memory: stores the programs and configuration files of the firewall.
z
Boot ROM: stores the boot and initialization programs of the firewall.
