Installing the Cisco NCS 4201

Connecting a Management Ethernet Cable

When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates

in the auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the

Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to

it.

However, when the Ethernet Management port is configured to a fixed speed (10, 100, or 1000 Mbps) through

command-line interface (CLI) commands, the port is forced to the MDI mode.

When in a fixed-speed configuration and MDI mode:

• Use a crossover cable to connect to an MDI port

• Use a straight-through cable to connect to an MDI-X port

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,

Warning

connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The

intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building

port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to

the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or

Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The

addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically

to OSP wiring. Statement

Installing and Removing SFP and SFP+ Modules

The Cisco NCS 4201 supports a variety of SFP and SFP+ modules, including optical and Ethernet modules.

For information on how to install and remove SFP and SFP+ modules, see the documentation for the SFP or

SFP+ module at:

For information about inspecting and cleaning fiber-optic connections, see:

for Fiber-Optic

We recommend that you wait for 30 seconds between the removal and insertion of an SFP on an interface

Caution

module. We recommend this to allow the transceiver software to initialize and synchronize with the Cisco

NCS 4201. Changing an SFP quicker could result in transceiver initialization issues that disable the SFP.

Connecting a USB Flash Device

To connect a USB flash device to the Cisco NCS 4201, insert the memory stick in the USB port labeled USB

MEM. The Flash memory module can be inserted only one way, and can be inserted or removed regardless

of whether the chassis is powered up or not.
