Before you perform any module replacement, read the "Safety Warnings" section section and disconnect power when noted.

Safety Warnings


Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030



Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001



Warning Read the installation instructions before connecting the system to the power source. Statement 1004



Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026


Replacing Power Supplies and Redundant Power Supplies

The Cisco 2010 CGR routers have replaceable power supplies. Use a Number 2 Phillips screwdriver to remove or install the power supply.


Caution Any combination of power supplies can be inserted into the chassis. Dual power supply configurations are load sharing in redundancy mode.

A single power supply is sufficient for supporting power needs to the system; however, if a single PSU is deployed it must be in slot 1 (PSU1).


Note The power supplies are hot swappable. The power supply LED must show it is properly functioning before removing the other power supply in the router.


Replacing the Cisco 2010 CGR Router Power Supply

To replace the power supply in a Cisco 2010 CGR router, perform the following steps. See Figure 5-1 for the locations of connectors and other components within the Cisco 2010 CGR router.


Step 1 Loosen the captive screws that fasten the power supply to the chassis.

Step 2 Pull the power supply out of the chassis. See Figure 5-1.

Step 3 Insert the replacement power supply into the chassis. See Figure 5-1.

Step 4 Tighten the captive screws that fasten the power supply to the chassis.


Removing and Installing Compact Flash Memory Cards

This section describes installing and replacing compact flash (CF) memory cards in Cisco 2010 CGR routers. It contains the following sections:

Preventing Electrostatic Discharge Damage

Removing a Compact Flash Memory Card

Installing a Compact Flash Memory Card

Preventing Electrostatic Discharge Damage

Compact flash memory cards 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:

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

Connect the equipment end of the strap to an unfinished chassis surface.

Place a removed compact flash 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.

Avoid 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.

Do not remove the wrist strap until the installation is complete.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Removing a Compact Flash Memory Card

To remove a compact flash memory card from the chassis, perform the following steps. See Figure 5-2, Figure 5-3, and Figure 5-4.


Caution Do not remove a compact flash memory card from the chassis while it is being accessed. The CF LED blinks to indicate when flash memory is being accessed. Removing the compact flash memory card from the router while flash memory is being accessed can cause data corruption and erratic operation.


Step 1 Remove the compact flash cover by placing a flat-blade screwdriver in the slot and pushing sideways against the tension to release the cover door. (See Figure 5-2 and Figure 5-3.)

Figure 5-2 Inserting Screwdriver Into the Compact Flash Cover

Figure 5-3 Removing the Compact Flash Cover

Step 2 Press the ejector button next to the compact flash memory card. The ejector button moves outward so that it projects from the panel.

Step 3 Press the ejector button again. See Figure 5-4. This ejects the compact flash memory card part-way out of its slot.

Step 4 Pull the compact flash memory card out of its slot.

Step 5 Push the ejector button in until the button is flush with the bezel.


Caution To prevent damage to the ejector mechanism, the ejector button must remain pressed in all the way (flush against the bezel) when not being used to eject a compact flash memory card.


Installing a Compact Flash Memory Card

To install a compact flash memory card, perform the following steps:


Step 1 Make sure that the ejector button is fully seated until it is flush with the bezel.


Note If the ejector button is projecting out from the panel, push it in until it is flush with the bezel.


Step 2 Insert the compact flash memory card into the slot until it is fully seated. The ejector button remains flush with the panel.


Note If the ejector button is projecting from the panel after you insert the compact flash memory card, remove the compact flash memory card, press the ejector button until it clicks, and reinsert the compact flash memory card.



Caution To prevent damage to the ejector mechanism, the ejector button must remain fully seated when not being used to eject a compact flash memory card.

Step 3 Replace the compact flash cover by inserting the cover lip into the chassis then pushing the over to snap it back into place.


Installing SFP Modules

This section describes how to install optional small-form-factor pluggable (SFP) modules in Cisco 2010 CGR routers to provide optical Gigabit Ethernet connectivity.

The rugged SFP SKUs supported on the Cisco 2010 CGR:

GLC-FE-100FX-RGD=

GLC-FE-100LX-RGD=

GLC-SX-MM-RGD=

GLC-LX-SM-RGD=

GLC-ZX-SM-RGD=

The SFP module installs into a slot on the router's cable side panel. When selected in Cisco IOS software, it is assigned port gigabitethernet 0/0. The default is the built-in RJ-45 1000 Base-T connector, which is enabled on this port.


Tip Use the show controller command at the Cisco IOS prompt to determine whether you are using an SFP certified by Cisco.


Laser Safety Guidelines

Optical SFPs use a small laser to generate the fiber-optic signal. Keep the optical transmit and receive ports covered whenever a cable is not connected to the port.

Follow these steps to install an SFP module in a Cisco 2010 CGR router:


Step 1 Slide the SFP into the router connector until it locks into position (see Figure 5-5).


Tip If the SFP uses a bale-clasp latch (see Figure 5-5), the handle should be on top of the SFP module.


Figure 5-5 Installing an SFP Module


Caution Do not remove the optical port plugs from the SFP until you are ready to connect cabling.

Step 2 Connect the network cable to the SFP module.


Removing SFP Modules

Follow these steps to remove an SFP from a Cisco 2010 CGR router:


Step 1 Disconnect all cables from the SFP.


Caution The latching mechanism used on many SFPs locks the SFP into place when cables are connected. Do not pull on the cabling in an attempt to remove the SFP.

Step 2 Disconnect the SFP latch (see Figure 5-6).


Note SFP modules use various latch designs to secure the module in the SFP port. Latch designs are not linked to SFP model or technology type. For information on the SFP technology type and model, see the label on the side of the SFP.

Tip Use a pen, screwdriver, or other small straight tool to gently release a bale-clasp handle if you cannot reach it with your fingers.


Step 3 Grasp the SFP on both sides and remove it from the router.


Installing Grid Router WAN Interface Cards

This section describes how to install grid router WAN interface cards (GRWIC) in Cisco 2010 CGR routers.

The GRWIC installs into one of four slots on the cable side panel of the router (see Figure 5-8).


Note You can install 4 single-wide GRWICs in the Cisco 2010 CGR router slots at any one time. Although double-wide GRWICs are not supported at this time, future versions of the Cisco 2010 CGR router will also support double-wide GRWIC configurations.


Figure 5-7 GRWICs for the Cisco 2010 CGR Router

Follow these steps to install a GRWIC in a Cisco 2010 CGR router:


Step 1 Slide the GRWIC in to the router slot. See Figure 5-8.

Figure 5-8 Proper Installation of Multiple GRWICs

Step 2 Tighten the three captive screws on the front of the interface card.


Caution For T1/E1 interfaces, shielded cables are required to meet EN55022, Cispr 22, and EN300-386 compliance.


Note When installing multiple GRWICs, the GRWICs must overlap, as shown in Figure 5-9, to ensure a secure fit.
