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.)
Caution 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.
