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.
