Chapter 6 Maintaining Hardware
When maintaining router hardware, note that:
z On a mounting screw of your router chassis, there is an anti-dismantle seal of
3Com Corporation. You must keep it in good condition when asking your sales
agent for servicing. You can open the chassis yourself but with permission of
your sales agent and must operate following the related rules. The company is
not liable for any damage or consequence resulting from users’ operation without
permission.
z Do not replace the hardware unless necessary and under the guidance of
technical staff.
z Ensure that no electricity is present before servicing the device to avoid bodily
injuries and device damage.
z Wear an ESD-preventive wrist strap when servicing the device, making sure it
has good skin-contact.
z Use the SDRAMs provided by 3Com Corporation only. Otherwise, anomalies
might occur to the device.
