Reconﬁgure the Router

Note: Cisco uBR924 cable access routers are typically conﬁgured at the headend. Most subscriber sites do not

permit local conﬁguration. Remote conﬁguration is either disabled or routinely reset to settings in the

provisioning or billing systems.

Caution

contact your network management, provisioning, or billing system administrator to ensure remote

conﬁguration is allowed. If remote conﬁguration is disabled, settings you make and save at the local site

will not remain in effect after the router is powered off and on. Instead, settings will return to the

previous conﬁguration.

Connect the Console Port

Step 1

Conﬁgure the terminal to support:

• 9600 baud

• 8 data bits

• No parity

• 1 stop bit (8N1)

Step 2

Connect the terminal to the Cisco uBR924 cable access router's console port.

Note: The console port is conﬁgured as DCE and uses an RJ-45 connector. The port is wired the same as all

other Cisco products.

Caution

changes, power cycle the router if that laptop will not be used at the subscriber site. This is particularly

important when the Cisco uBR924 is conﬁgured to operate in a DOCSIS-compliant bridging mode.

Power cycling the Cisco uBR924 ensures the laptop computer does not remain in the list of CPE devices

at the subscriber site for the Cisco uBR924 to support. Only reinitialization of the cable interface clears

out the bridge table and resets the counter that speciﬁes the number of CPE devices being bridged. Refer

to the "Basic Internet Access Bridging Example" section of this document.

Note: This behavior is in accordance with DOCSIS. For conﬁgurations including Cisco Series 7200 CMTS

equipment, issuing the clear cable modem host <mac address> command may be required to clear the laptop

from the headend security access control tables.
