Cisco Gigabit Ethernet High-Speed WAN Interface Cards
The Cisco Gigabit Ethernet high-speed WAN interface card (HWIC-1GE-SFP) is a high-speed interface card providing copper and optical Gigabit Ethernet connectivity for Cisco modular access routers.
The Cisco Gigabit Ethernet high-speed WAN interface card provides copper and optical Gigabit Ethernet connectivity through a small form-factor pluggable module (SFP), which is inserted into the interface card. (See the "Installing Small Form-Factor Pluggable Modules into Cisco Gigabit Ethernet High-Speed WAN Interface Cards" section.)
SFPs can be installed or removed without powering down the router and interface card.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet high-speed WAN interface card (HWIC-1GE-SFP) only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.
Note The Cisco Gigabit Ethernet high-speed WAN interface card itself is not hot-swappable. Removal or insertion of the Cisco Gigabit Ethernet high-speed WAN interface card requires powering down the router.
The Cisco Gigabit Ethernet high-speed WAN interface card supports the SFPs shown in Table 34.

Note Only Cisco-certified SFPs are supported on the Cisco Gigabit Ethernet high-speed WAN interface card.
Tip When switching from one type of SFP to another, connection problems, including connection failure, may result. Use the show controller command at the Cisco IOS command-line interface (CLI) to determine whether you are using an SFP certified by Cisco.
Different SFPs have different cabling requirements; see the "Cabling for Small Form-Factor Pluggable Modules" section for more information on SFP cabling.
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.
The interface card faceplate carries a Class 1 laser warning label. (See Figure 115.)
Figure 115 Class 1 Laser Warning Label
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
Cisco Gigabit Ethernet High-Speed WAN Interface Card LEDs
The Cisco Gigabit Ethernet high-speed WAN interface card uses LEDs to indicate card status and activity. (See Figure 116.)

Installing Small Form-Factor Pluggable Modules into Cisco Gigabit Ethernet High-Speed WAN Interface Cards
Small form-factor pluggable modules (SFPs) are hot-swappable Ethernet interfaces that can be installed directly into the Cisco Gigabit Ethernet high-speed WAN interface card. See Table 34 for SFPs supported on the Cisco Gigabit Ethernet high-speed WAN interface card.
To install an SFP into the Cisco Gigabit Ethernet high-speed WAN interface card, perform the following steps:
Step 1 Install the interface card in the router. (See Chapter , "Installing Cisco Interface Cards in Cisco Access Routers.")
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Step 2 Slide the SFP into the housing on the interface card until it is locked into position. (See Figure 117.) The SFP is designed to prevent improper insertion.
Tip If the SFP uses a bale-clasp latch (see Figure 117 and Figure 118), the bale-clasp handle should be on top of the SFP in the closed position for proper seating of the SFP module.
Figure 117 Installing an SFP on the Cisco Gigabit Ethernet High-Speed WAN Interface Card
Caution Do not remove the optical port plugs used on the SFP until you are ready to connect cabling to the interface card.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet high-speed WAN interface card (HWIC-1GE-SFP) only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.
Step 3 Connect the interface card to the network. (See the "Connecting Cisco Gigabit Ethernet High-Speed WAN Interface Cards to the Network" section.)
Removing Small Form-Factor Pluggable Modules from Cisco Gigabit Ethernet High-Speed WAN Interface Cards
This section describes a generic removal procedure. Small form-factor pluggable modules (SFPs) use various latch designs (see Figure 118) to secure the module in the SFP port.
Note 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 top or side of the SFP.
Removing SFPs from Cisco Gigabit Ethernet High-Speed WAN Interface Cards
To remove an SFP from a Cisco Gigabit Ethernet high-speed WAN interface card, perform the following steps:
Step 1 Disconnect all cables from the SFP.
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Caution The latching mechanism used on many SFPs locks the SFP into place whenever cables are connected. Do not pull on the cabling in an attempt to remove the SFP.
Step 2 Disconnect the SFP latch (see Figure 118).

Tip Use a pen, screwdriver, or other small, straight tool to gently release the bale-clasp handle if you cannot reach it with your fingers.
Step 3 Grasp the SFP on both sides and remove it from the interface card.
Cabling for Small Form-Factor Pluggable Modules
Cisco Gigabit Ethernet high-speed WAN interface cards connect to the network through various supported small form-factor pluggable modules (SFPs). Cabling requirements vary by SFP. See the "Cabling for Small Form-Factor Pluggable Modules" section.
For information on cabling requirements for various small form-factor pluggable modules (SFPs) supported by the Cisco Gigabit Ethernet high-speed WAN interface card, see Table 35.

Cisco Gigabit Ethernet high-speed WAN interface cards are designed for use in the following network design scenarios:
•In metropolitan-area network (MAN) backbones for low-cost, high-speed, and long-distance connectivity
•In multiprotocol WAN gateway routers for LANs
•In same-building or same-campus wiring closets to achieve high-speed connectivity for high-demand network segments
Tip For more information on possible network configurations using the Cisco Gigabit Ethernet high-speed WAN interface card, see Cisco product documentation.
Connecting Cisco Gigabit Ethernet High-Speed WAN Interface Cards to the Network
To connect the Cisco Gigabit Ethernet high-speed WAN interface card to the network, perform the following steps:
Step 1 Confirm successful insertion of the SFP.
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Step 2 Confirm that the router is powered down.
Step 3 Remove optical port plugs from the installed SFP.
Step 4 Use the appropriate cable (see Table 35) to connect to the installed SFP.
Note For short distances or loopbacks, network installations using 1000BASE-CWDM and 1000BASE-ZX SFPs may require 15-dBm attenuators to avoid over-powering the connection. Calculate the power budget for the connection to determine which attenuator to use.
Step 5 For network installations that use 1000BASE-CWDM SFPs, connect the SFP to a Cisco CWDM optical add-drop multiplexing (OADM) interface card. (See Figure 120.) For information on the Cisco CWDM OADM, see the Installation Note for the Cisco CWDM Passive Optical System document.
Figure 120 Using a Cisco CWDM OADM Card to Connect the Cisco Gigabit Ethernet High-Speed WAN Interface Card to the Network
Step 6 Connect the other end of the appropriate cable (see Table 35) to your network.
Step 7 Continue router startup and configuration tasks.
