This chapter provides information on the ATM CES port adapter and its use on the Cisco 7200 series router. This chapter contains the following sections:
The ATM CES port adapter, which is dual-wide, can be installed in any available, horizontally aligned pair of port adapter slots in a Cisco 7200 series router. Figure 3-1 shows an ATM CES port adapter installed in port adapter slot 3 and slot 4 of a Cisco 7206 router.
You might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case, no tools are necessary; any port adapter available for the Cisco 7200 series routers connects directly to the router midplane and is locked into position by a port adapter lever. See "Preparing for Installation," for a list of tools required for removing and replacing a port adapter.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot. This allows the router to conform to EMI emissions requirements and helps provide proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter.
The ATM CES port adapter is a dual-wide port adapter and requires two adjacent port adapter slots in a Cisco 7200 series router.
Following is the procedure for removing a port adapter from a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap to yourself and to an unfinished chassis surface.
Step 2 Move the port adapter lever for the desired port adapter slot to the unlocked position. (See Figure 3-2.)
Step 3 Grasp the two handles on the port adapter and pull the port adapter from the midplane, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter out of the chassis slot.
Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.
Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.
 | Caution Always handle the port adapter by the carrier edges and handles; never touch the port adapter's components or connector pins. (See Figure 3-3.) |
Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a static shielding bag. If you are returning the port adapter to Cisco, immediately place it in a static shielding bag.
Following is the procedure for removing a port adapter slot divider from a Cisco 7200 series router:
Step 1 Remove the port adapters from the slots on both sides of the port adapter slot divider. Refer to the previous "Removing a Single-Width Port Adapter" section when removing a port adapter from a Cisco 7200 series router.
Step 2 With one hand, raise the slot divider lever to unlock the slot divider from the chassis. (See Figure 3-4.)
Step 3 With the slot divider lever still raised, use your other hand to pull the slot divider from the chassis. (See Figure 3-5.)
Step 4 Store the slot divider for use at a later date.
This completes the procedure for removing a port adapter slot divider from a Cisco 7200 series router. Proceed to the "Installing a Dual-Width Port Adapter" section.
Following is the procedure for installing a port adapter slot divider in a Cisco 7200 series router.
Step 1 Position the slot divider so that the slot divider lever faces you and is at the bottom.
Step 2 Align the left and right edges of the slot divider between the guides in the port adapter slot. (See Figure 3-6.)
Step 3 With the left and right edges of the slot divider aligned in the slot guides, slide the slot divider all the way into the slot until you feel the slot divider lock into place (listen for a click).
This completes the procedure for installing a port adapter slot divider in a Cisco 7200 series router.
Following is the procedure for installing a new dual-wide port adapter in a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap to yourself and to an unfinished chassis surface.
Step 2 Use both hands to grasp the port adapter by its metal carrier edges with the adapter components facing downward. (See Figure 3-3.)
Step 3 Align the left and right edges of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 3-7.)
Step 4 With the metal carrier edges aligned in the slot guides, gently slide the port adapter halfway into the slot.
| Caution Do not slide the port adapter all the way into the slot until you have connected all cables. Doing so disrupts normal operation of the router. |
Step 5 With the port adapter halfway into the slot, connect all required cables to the port adapter.
Step 6 After connecting all required port adapter cables, carefully slide the port adapter all the way into the slot until you feel the port adapter's connectors mate with the midplane.
Step 7 After feeling the connectors mate, move the port adapter lever to the locked position. Figure 3-8 shows the port adapter lever in the locked position.
This completes the procedure for installing a new port adapter in a Cisco 7200 series router. Proceed to the following section,"Setting ATM CES Port Adapter Jumpers."
Depending on the circumstances, you might need to change the configuration of the ATM CES port adapter's receive interface from ungrounded to grounded. (The ATM CES port adapter is configured in manufacturing for ungrounded at the receive interface.) The following steps explain how to set the configuration for grounded or ungrounded:
Step 1 Attach an ESD-preventive wrist strap to yourself and to an unfinished chassis surface.
Step 2 Remove the ATM CES port adapter from the chassis. To do so, follow the steps in the "Removing a Single-Width Port Adapter" section.
Step 3 With the ATM CES port adapter on an antistatic mat, use a number 1 Phillips screwdriver to remove the three screws that secure the plastic shield to the ATM CES port adapter's printed circuit board. (See Figure 3-9.) Save the screws.
Step 4 Set the jumper on the ATM CES port adapter to grounded (covered pins) or ungrounded (uncovered pins). This jumper is at location E1 on the port adapter's circuit board. See Figure 3-10.
Step 5 Replace the plastic shield over the ATM CES port adapter's jumper and secure the shield to the port adapter's printed circuit board using a number 1 Phillips screwdriver and the three screws that you saved.
Step 6 Replace the ATM CES port adapter in the chassis. To do so, follow the instructions in the "Installing a Dual-Width Port Adapter" section.
This completes the procedure for setting the ATM CES port adapter jumper(s). Proceed to
"Configuring the ATM CES Interface," for information on configuring and customizing the ATM CES port adapter.
