External Non-Cisco Module Support

This section describes the support for, and requirements for, installing a non-Cisco module on the router.

Caveats

blank.gifCisco does not provide technical support for issues related to non-Cisco products. You must contact the module supplier or your reseller to obtain technical support for the non-Cisco module.

blank.gifInstalling a module that does not meet the requirements described in this section can negatively affect router performance.

blank.gifThe router system software does not communicate with or interact with non-Cisco modules.

blank.gifA non-Cisco module that is installed on the router does not interact with the router chassis. Connecting a non-Cisco module to the router does not certify the module. Before installing the module, verify that it is certified for use in your environment.

External Non-Cisco Module Requirements

Non-Cisco modules installed on the router exterior must meet the following requirements:

blank.gifCompliance with Type 4X and IP67 standards.

blank.gifSupport the router mounting boss dimensions (see Figure 96).

Cable Requirements

Cables used for installing an external, non-Cisco module should meet the following criteria:

blank.gifOutdoor-rated

blank.gifUV-stabilized

blank.gifDiameter of 0.20-0.35 inches (5.08-8.89 mm)

Caution: Cables must be a minimum of 0.20 in. in diameter to create an adequate seal within the cable glands. Using smaller cables could result in an inadequate seal and expose the router interior to environmental elements.

blank.gif Power cable —The cable that you provide to connect the module to the router 12V power connector must be wired so that Pin 3 (cable presence) and Pin 4 (ground) are connected to each other. If they are not connected, the module will not detect power from the router. Refer to External Non-Cisco Module Support.

Online Installation and Removal

An external non-Cisco module can be installed or removed while the router is installed (usually on a pole top) and operating normally.

The module must be powered off until it is connected to a power source as part of the installation process described in this section. Power sources can include:

blank.gifRouter Power over Ethernet (PoE) Ethernet port (see Router Hardware Description)

blank.gifRouter 12V power connector, illustrated and described in Figure 98

blank.gifExternal-to-the-router power source

Power

The router interior features a 4-pin, Micro-Fit 3.0 connector, which provides 12 volts of power to an externally-connected module. See Figure 98 for an illustration of the power connector.

Before Installing

Read this section and Installation Safety and Site Preparation before following any installation procedures.

Prepare the Installation Site

The installation site must be prepared according to Installation Safety and Site Preparation.

Preventing Electrostatic Discharge Damage

Many of the components discussed in this chapter are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly, results in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

blank.gifAlways use an ESD wrist or ankle strap and ensure that it makes good skin contact.

blank.gifConnect the equipment end of the strap to an unfinished chassis surface.

blank.gifPlace the removed memory card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.

blank.gifAvoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

blank.gifDo not remove the wrist strap until the installation is complete.

Cabling Guidelines

Follow these guidelines for using cables with the router:

blank.gifPosition cables so that they do not place strain on the router connectors.

blank.gifOrganize cables into bundles when necessary to avoid intertwining.

blank.gifInspect cables to ensure adequate routing and bend radius.

blank.gifInstall cable ties that comply with your site requirements.

blank.gifExternal Cabling

blank.gifInternal Cabling

External Cabling

Depending on the dimensions of the module, you might have to connect the module to the router in a way that the cables are exposed outside the router and the module.

With this configuration:

blank.gifCables are exposed externally

blank.gifUse cable glands to thread cables through the cable ports

blank.gifFollow the cabling instructions in this section

Cisco Cable Glands

When you install the module in a configuration that uses external cabling from the module through the cable ports on the router door, you must provide cable glands for each cable port.

Cable glands:

blank.gifCreate seal to protect the router interior from environmental elements

blank.gifCan be ordered from Cisco: CGR-IP67GLAND (one cable gland per kit)

blank.gifSee Cable Glands Description

Caution: The cable glands must be used for all cables that are threaded through the router chassis cable ports to prevent exposing the router interior to environmental elements.

Outdoor Cable Requirements

Verify that the cables you use to connect the module to the router meet the cable requirements described in Cable Requirements.

Connecting the Cable Glands

To connect the cable glands to a router cable port:

1.blank.gif Use the 13-mm wrench to remove the port plugs from the cable ports on the router door.

2.blank.gif Follow the steps in Cable Glands Installation Steps to:

blank.gifThread the Ethernet and power cables through the cable glands

blank.gifConnect the cable glands to the cable ports on the router door

Internal Cabling

Depending on the module dimensions and the location of the module cables, you may be able to install the module directly over the cable ports and thread the module cables through the cable ports.

With this configuration:

blank.gifCables are not exposed externally.

blank.gifInstall an O-ring in each cable port to create an environment-proof seal.

blank.gifFollow the cabling instructions in this section.

Cisco O-Ring

When you install the module in a configuration that uses internal cabling from the module, through the cable ports on the router door, insert a rubber O-ring into each port to create an environmental-proof seal.

Caution: The O-ring must be used to prevent exposing the router interior to environmental elements.
