This chapter describes how to remove the PA-5EFL port adapter from supported platforms and also how to install a new or replacement port adapter. This chapter contains the following sections:
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.
 |
Note When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to electromagnetic interference (EMI) emissions requirements and to allow 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 the blank port adapter. |
 |
Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 3-1.) |
Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-5EFL on Cisco 7100 series routers Cisco 7200 series routers, or the Cisco uBR7246 series routers.
Although the VIP2 supports online insertion and removal, individual port adapters do not. To replace port adapters, you must first remove the VIP2 from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must first remove the VIP2 from the chassis and then remove the blank port adapter.
|
Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or attempt to install other port adapters on the motherboard when the system is operating. To install or replace port adapters, first remove the VIP2 from its interface processor slot. |
|
Note As you disengage the port adapter from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the port adapter. |
|
Note Before you begin installation, read "Preparing for Installation," for a list of parts and tools required for installation. |
Observe the following warnings and cautions when installing or removing port adapters.
|
Caution Do not slide a port adapter all the way into the slot until you have connected all required cables. trying to do so disrupts normal operation of the router or switch. |
|
Note If a port adapter lever or other retaining mechanism does not move to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position. |
|
Caution To prevent jamming the carrier between the upper and lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustrations. |
 |
Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself. |
In this section, the illustrations that follow give step-by-step instructions on how to remove and install port adapters. This section contains the following illustrations:
Connect ST fiber-optic cables to the PA-5EFL as follows:
|
Note Port adapters have a handle attached, but it is not shown in to allow a full view of the detail on each port adapter's faceplate. |
Step 2 Attach the TX multimode fiber-optic cable directly to the TX port on the PA-5EFL. (See Figure 3-2.)
Step 3 Connect a 5EFL RX port to the appropriate TX port of the repeater, hub, DTE, or other external 10Base-FL equipment.
Step 4 Connect a 5EFL TX port to the appropriate RX port of the repeater, hub, DTE, or other external 10Base-FL equipment.
Step 5 Repeat Steps 1 and 4 for each additional 5EFL interface connection you require.
This completes the procedure for attaching a multimode fiber-optic cable to the PA-5EFL. Proceed to "Configuring the PA-5EFL."
