  Connecting an External Ethernet Switch
Connecting an External Ethernet Switch 
If more than four PCs in an office must be connected to each other, you can add Ethernet connections to 
the router by connecting an external Ethernet switch to the router’s Ethernet switch. 
To connect an external Ethernet switch to an Ethernet switch port on the router, perform the following 
steps:
Step 1Connect one end of the yellow Ethernet cable to an Ethernet switch port on the router. Figure 3-3 shows 
a Cisco 888W router connected to an Ethernet switch.
Figure 3-3 Connecting to an Ethernet Switch
Step 2Connect the other end of the cable to the available port on the Ethernet switch to add additional Ethernet 
connections.
Step 3Turn on the Ethernet switch.

Connecting the V.92 modem Port
WarningHazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF 
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, 
detach the end away from the unit first. Statement 1026
For dialup connection to your service provider network through the V.92 port, follow the steps given 
after 
Figure 3-4, which show this connection.
Figure 3-4 Connecting to Your Service Provider Through the V.92 port
To connect the router to your service provide network through the V.92 port, follow these steps:
Step 1Connect one end of the straight-through R-J11 cable to the V.92 port. 
Step 2Connect the other end of the straight through R-J11 cable to an RJ-11 telephone wall outlet.

  Connecting a Terminal or PC to the Console Port
Connecting a Terminal or PC to the Console Port
Connect a terminal or PC to the Console Aux port either to configure the software by using the 
command-line interface (CLI) or to troubleshoot problems with the router. 
To connect a terminal or PC to the console port on the router and access the CLI, follow these steps:
Step 1Connect the RJ-45 end of a DB-9–to–RJ-45 serial cable to the RJ-45 Console Aux port on the router. 
Figure 3-5 shows the RJ-45 end of the serial cable connected to the Console Aux port on the router. 
Figure 3-5 Connecting a Terminal or PC to the Console Port
Step 2Connect the DB-9 end of the DB-9–to–RJ-45 serial cable to the to the COM port on your laptop or PC.
NoteSome laptops and personal computers do not come with DB-9 serial port connectors and may 
require a USB-to-serial port adapter.
Step 3To communicate with the router, start a terminal emulator application.

  Connecting the 3G Card
Step 4Make sure that your modem and the router auxiliary port are configured for the same transmission speed 
(up to 115200 bits per second [b/s] is supported) and support mode control with data carrier detect 
(DCD) and data terminal ready (DTR).
Connecting the 3G Card
NoteThe Cisco 880G router does not support OIR of the 3G card. You must enter the shutdown command on 
the cellular interface before you remove the 3G card from the router. 
To connect and secure the 3G card, follow these steps:
Step 1Align the 3G card to the 3G express card slot, as shown in Figure 3-7. Keep the card parallel to the 
surface and firmly push the card into the slot.
TipHolding the 3G card on the flat metal surface will make it easier to align and insert the 3G card.
NoteWhen inserting the card into the 3G express card slot, you may hear a metal-on-metal sound as 
the 3G card rubs against the internal metal cage. The 3G card is designed to fit tightly into the 
3G express card slot. Firm pressure may be required to insert the card.
NoteGlobal System for Mobile Communications (GSM) customers need to insert a SIMM card, 
provided by their network carrier, into the 3G card.
