Chapter 3 Connecting the Router
Connecting the 3G Card
Step 2 Connect the DB-9 end of the console cable to the DB-9 end of the modem adapter.
Step 3 Connect the DB-25 end of the modem adapter to the modem.
Step 4 Make 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
Note For information on embedded multiband, multiservice WAN modems, see Configuring Cisco EHWIC
and 880G for 3G (EV-DO Rev A) and Configuring Cisco EHWIC and 880G for 3.7G (HSPA+)/3.5G
(HSPA).
Note The Cisco 880G router does not support online insertion and removal (OIR) of the third-generation (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 1 Align 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.
Tip Holding the 3G card on the flat metal surface makes it easier to align and insert the 3G card.
Note When 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.
Note Global System for Mobile Communications (GSM) customers need to insert a SIM card,
provided by their network carrier, into the 3G card.
