Required Tools and Equipment for Installation and Maintenance


1000BASE-X—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable
(IEEE 802.3z). Supports the Ethernet maximum length of 328 feet (100 meters).

1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable
(IEEE 802.3ab). Supports the Ethernet maximum length of 328 feet (100 meters).

100BASE-TX—100 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable
(IEEE 802.3u). Supports the Ethernet maximum length of 328 feet (100 meters).

Serial Connections

Before you connect a device to a serial port, you need to know the following:

Type of device, data terminal equipment (DTE) or data communications equipment (DCE)

Type of connector, male or female, required to connect to the device

Signaling standard required by the device
These are the most common devices connected to the router serial ports:
Serial Devices
Devices such as RTU or
IED with serial
asynchronous interface
Note: No synchronous
serial protocol support
Connecting

You must provide or purchase separately the correct serial cable. The cable does not ship with the router. Contact
your Cisco reseller to purchase the correct cable from Cisco.

You can connect a device to this port while the router is operating normally.

The serial ports are labeled SER 1/1 and SER 1/2.
