Cisco 910 Industrial Router Installation
Additional Router Connections
Connecting a USB Port
See
Figure 1
for the USB port location.
You can connect an optional USB device to the USB port, which will provide power to the USB device. You can also
connect a USB device that is powered by an external power source, such as an AC adapter or batteries.
Before you connect a USB port, you need to know the following:
You can connect the USB device to the port while the router is operating normally.
Depending on the USB device you connect to the port, you might require a USB extension cable to connect the USB
device to the port.
To prevent the connected USB device from being stolen or accidentally removed, secure any connected USB device
with a locking mechanism designed for this purpose.
Connecting an SFP Port
See
Figure 1
for the SFP port location.
Small Form-Factor Pluggable (SFP) modules are transceiver devices that plug into the router SFP connectors. The
transceiver connects the electrical circuitry of the module with the optical network.
The SFP module used on the port must match the wavelength specifications on the other end of the cable, and the cable
must not exceed the stipulated cable length for reliable communications.
Use only Cisco SFP transceiver modules with the router. Each SFP transceiver module supports the Cisco Quality
Identification (ID) feature that allows a Cisco switch or router to identify and validate that the transceiver module is
certified and tested by Cisco.
For detailed instructions on installing, removing, and cabling the SFP transceivers, see the corresponding SFP module
documentation.
Warning:
Class 1 laser product. Statement 1008
Caution:
Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the fiber-optic
cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from
contamination and ambient light.
Caution:
You are not recommended to install or remove the SFP module while the fiber-optic cable is attached to it,
because of potential damage to the cables, to the cable connector, or to the optical interfaces in the SFP module.
Disconnect the fiber-optic cable before you remove or install an SFP module.
Materials and Tools Required
You must provide these tools and materials to install an SFP transceiver module:
Wrist strap or other personal grounding device to prevent ESD occurrences.
Antistatic mat or antistatic foam to set the transceiver on.
Fiber-optic end-face cleaning tools and inspection equipment. For complete information on inspecting and cleaning
fiber-optic connections, see white-paper at:

Before you connect an SFP port, you need to know the following:
You can connect an SFP module to the port while the router is operating normally.
