Cisco Gigabit Ethernet Enhanced High-Speed WAN Interface Cards

The Cisco Gigabit Ethernet WAN EHWIC (EHWIC-1GE-SFP-CU) is an enhanced high-speed interface card providing copper and optical Gigabit Ethernet ports and connectivity of T1/E1 and T3/E3 over copper for Cisco ISR.

The Cisco Gigabit Ethernet enhanced high-speed WAN interface card provides copper and optical Gigabit Ethernet connectivity through a dual-purpose uplink (DPU).

Supported Platforms

The EHWIC-1GE-SFP-CU interface card supports the following Cisco ISRs:

•Cisco 1921 ISR

•Cisco 1941 ISR

•Cisco 2901 ISR

•Cisco 2911 ISR

•Cisco 2921 ISR

•Cisco 2951 ISR

•Cisco 3925 ISR

•Cisco 3925E ISR

•Cisco 3945 ISR

•Cisco 3945E ISR

Dual-Purpose Uplink Small Form-Factor Pluggable Module

This section describes DPU small form-factor pluggable modules (SFPs).

For installation instructions to install SFPs in EHWIC-1GE-SFP-CU interface cards, see the Cisco 3900 Series and Cisco 2900 Series Hardware Installation Guide.

---

Note SFPs can be installed or removed without powering down the router and interface card.

---

---

Note The Cisco Gigabit Ethernet EHWIC itself is not hot-swappable. Removal or insertion of the Cisco Gigabit Ethernet EHWIC requires powering down the router.

---

Warning Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet T1/E1 or T3/E3 interface 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, Issue 4) 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 7003

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 CLI to determine whether you are using an SFP certified by Cisco.

Different SFPs have different cabling requirements; see Cisco 3900 Series and Cisco 2900 Series Hardware Installation Guide 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.

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

Connecting Cisco Gigabit Ethernet Enhanced High-Speed WAN Interface Cards to the Network

This section describes how to properly connect to SFPs. For information on how to install SFPs, see Cisco 3900 Series and Cisco 2900 Series Hardware Installation Guide.

To connect the Cisco Gigabit Ethernet EHWIC 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 Remove optical port plugs from the installed SFP.

Step 3 Use the appropriate cable (See Table 3.) 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 4 For network installations that use 1000BASE-CWDM SFPs, connect the SFP to a Cisco CWDM optical add-drop multiplexing (OADM) interface card. (See Figure 3.) For information on the Cisco CWDM OADM, see Installation Note for the Cisco CWDM Passive Optical System.

1	EHWIC-1GE-SFP-CU	2	CWDM SFP (partially installed)
3	LC connector	4	Dual single-channel OADM module
5	To network	6	To network

Step 5 Connect the other end of the appropriate cable (See Table 3.) to your network.

Step 6 Continue router startup and configuration tasks.
