Cisco Interface Cards Installation

See the individual interface card installation guides on Cisco.com to install specific interface cards in chassis slots. Interface cards supported by the Cisco 1941 integrated services routers include the following types:

•VWIC—data mode only

•WAN interface cards (WICs)

•High-speed WAN interface cards (HWICs)

•Enhanced High-speed WAN interface cards (EHWICs)

Installing WICs, VWICs, HWICs, and EHWICs

This section describes how to install WICs, VWICs, HWICs, and EHWICs into Cisco 1941 routers.

---

Caution Do not connect a WAN cable to an interface card until you have completed its installation procedure.

---

The Cisco 1941 router has two interface card slots. Each slot can accommodate a Cisco WIC, VWIC (data only mode), or a single-wide high-speed WIC (HWIC).

---

Note Cisco double-wide HWICs are not supported in the Cisco 1941 router.

---

To install a card in a Cisco 1941 router, follow these steps:

---

Step 1 Make sure that the router is turned off and is disconnected from power.

---

Caution Power must be removed from the system prior to installing or removing interface cards to avoid damaging them. When interface cards are pushed into or pulled out of a router that is powered up, there is a strong possibility that they could be damaged electrically and would no longer function.

---

Step 2 Loosen the thumbscrews on the interface card blank faceplate on the back panel, as shown in Figure 8-1. You should be able to loosen the screws using your fingers; however, if the screws are very tight, you might need to use a Phillips screwdriver.

Step 3 Remove the blank faceplate that covers the card slot.

Step 4 Hold the interface card by the edges on either side of the card front panel, and line up the card edges with the guides inside the card slot, as shown in Figure 8-2.

Step 5 Insert the card in the slot, and gently push it into the router until the front panel of the card is flush with the back panel of the router.

Step 6 Tighten the screws.

Installing and Removing Slot Dividers

You can remove a slot divider between the single-wide EHWIC slot, converting it into one double-wide slot.

---

Note The EHWIC slots on both sides of a slot divider must be empty before you remove the slot divider.

---

To remove slot dividers from EHWIC slots on Cisco 1900 series routers, follow these steps:

---

Step 1 Loosen the retention screw on the slot divider. See Figure 8-5.

Step 2 Pull the slot divider straight out of the EHWIC slot.

Figure 8-3 shows the EHWIC slot divider for Cisco 1900 series routers.

To install slot dividers into EHWIC slots, follow these steps:

---

Step 1 Guide the slot divider between the two rails in the bottom of the EHWIC slot. Push the slot divider in until it is fully seated. When the slot divider is fully seated, its outer end is flush with the front panel of the router. See Figure 8-4.

Step 2 Tighten the retention screw on the slot divider. Figure 8-5 shows an installed slot divider.
