Replacing the Battery

Replacing the Battery

If you have made changes to the factory-default configuration but that factory-default configuration is restored when you boot the router, the battery may need to be replaced.

To replace the battery:

1.Disconnect the hub from the power source,

2.Using the supplied nutdriver, remove the two hex nut screws along- side the WAN port connector. (See figure 1-10 on page 1-15.)

3.Using a Torx T-10 or flat-blade screwdriver, loosen the two captured screws holding the cover plate over the hub’s Expansion Slot, then remove the cover plate. (See figure 1-3 on page 1-11.)

4.Connect a grounding wrist strap between your wrist and the hub. (Refer to step 2 on page 1-11.)

Static electricity can severely damage sensitive electronic components such as the router module or the SNMP module.

5.Remove the router and SNMP modules from the hub. (Refer to step 5 on page 1-12.) Place the modules, with the router module on the bottom, on a nonconducting antistatic surface.

6.Using a Phillips (cross-head) screwdriver, remove the four screws securing the SNMP module to the standoffs. (See figure 1-8 on page 1-14.)

7.Carefully disengage the connectors holding the two modules together, then place the SNMP module on an antistatic surface.
