Preparing Network Connections
When preparing your site for network connections to the router, you must consider a number of
factors related to each type of interface, such as the type of cabling required for each type (fiber, thick
or thin coaxial, or twisted-pair cabling), distance limitations for each signal type, the specific cables
you need to connect each interface, and any additional interface equipment you need, such as
transceivers, modems, channel service units (CSUs), or data service units (DSUs). Before installing
the router, have all additional external equipment and cables on hand. If you intend to build your own
cables, refer to the cable pinouts in the appendix "Cabling Specifications." For ordering information,
contact a customer service representative.
Additional and Optional Connection Equipment
You may need some of the following data communications equipment to complete your installation:

synchronous. When connecting serial devices such as modems or DSUs, connect only asynchronous
devices to the console and auxiliary ports, and synchronous devices to the FSIP serial ports.

2-18 Cisco 7010 Hardware Installation and Maintenance
Check the power at your site before installation and periodically after installation to ensure that
you are receiving clean power. Install a power conditioner if necessary.
Install proper grounding to avoid damage from lightning and power surges.
To install and configure the router, you need a terminal with an EIA/TIA-232 DTE port and an
EIA/TIA-232 DCE console cable with DB-25 plugs at both ends. You can detach the terminal
(and cable) after the installation and configuration procedures are complete.
The console and auxiliary serial ports are asynchronous, and the FSIP serial ports are
To use an IEEE 802.3 or Ethernet interface (thick-wire, thin-wire, or unshielded twisted-pair) at
your installation, you need an 802.3 media attachment unit (MAU) and an attachment unit
interface (AUI), or an Ethernet transceiver and transceiver cable. The AUI or transceiver cable
will need an AUI 15-pin plug to connect to the 15-pin AUI receptacle on the EIP. Some interface
equipment may use cables with screw-type locks rather than the slide-type locks that are standard
on the EIP. A kit for replacing the slide-type locks with screw-type locks is shipped with the EIP.
For IEEE 802.3u Fast Ethernet (100BaseT) connections to the FEIP, you need Category 5, UTP
cable for RJ-45 connections or Media Independent Interface (MII) cables for MII connections.
For more detailed Fast Ethernet cable requirements, refer to the section "Fast Ethernet
Connection Equipment" in this chapter.
To connect a 4- or 16-Mbps Token Ring interface, you need an IEEE 802.5 MAU and a Token
Ring adapter cable.
To use the optical bypass feature available with multimode/multimode and
single-mode/single-mode FDDI interfaces, you need an optical bypass switch. A
DIN-to-mini-DIN control cable for connecting the switch is included with the
multimode/multimode FIP (CAB-FMDD).
To use a low-speed synchronous serial interface, you need a synchronous modem or a (CSU/DSU
to connect to the network. Most modems require an EIA/TIA-232 DTE connection.
