Port Adapter Overview

The PA-H single-port HSSI port adapter, shown in Figure 1-1, provides one high-speed serial interface. The interface on the PA-H is considered a data terminal equipment (DTE) device. (Port adapters have a handle attached, but this handle is occasionally not shown in figures in this publication to allow a full view of detail on the port adapter faceplate.)

Figure 1-1 PA-H Port Adapter—Faceplate View

The HSSI network interface resides on a modular port adapter, which provides a direct connection between the high-speed bus in the router or switch and the external networks.


Note The Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, VIP, and Cisco 7304 PCI Port Adapter Carrier Card support online insertion and removal (OIR), but individual port adapters do not. To replace port adapters, you must first remove the Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, VIP, or Cisco 7304 PCI Port Adapter Carrier Card from the chassis and then replace port adapters as required.

The Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco uBR7246 routers, Cisco 7301 router, and Cisco 7401ASR router support the OIR of all port adapter types.


The currently shipping single-port PA-H can be identified by Rev. B in the lower right corner of its front-panel label. (See Figure 1-1.) The older PA-H does not have Rev. B on its label. (See Figure 1-2)

Figure 1-2 Older PA-H—Pre-Rev. B—Faceplate View

To determine which PA-H model you currently have installed, examine the faceplate or, use the show diag command. (For information on using the show diag command, see "Configuring the PA-H.")


Note You should replace older PA-H port adapters with the newer PA-H Rev. B port adapter. Contact Cisco's Technical Assistance Center (TAC) for replacement details.


Interface Specifications

The PA-H conforms with the BABT/TC/130 and EIA/TIA-612 and EIA/TIA-613 standards for HSSI. The PA-H provides one interface, which provides a full-duplex, high-speed, synchronous serial interface for transmitting and receiving data at rates of up to 52 megabits per second (Mbps).

The HSSI has been standardized as EIA/TIA 612/613 and provides access to services at T3 (45 Mbps), E3 (34 Mbps), and Synchronous Optical Network (SONET) STS-1 (51.82 Mbps) rates. The actual rate of the interface depends on the external DSU and the type of service to which it is connected.

The HSSI port on the PA-H is a female 50-pin SCSI-II-type receptacle. You must use the HSSI interface cable from Cisco Systems to connect the interface to an external DSU. See the "Cables, Connectors, and Pinouts" section for descriptions of HSSI cables.

The PA-H supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bit CRCs; to enable 32-bit CRCs, use a configuration command. (For a description of the CRC function, see "Configuring the PA-H.")

LEDs

The PA-H has one row of five status LEDs (TD, TC, RD, RC, and LB/C) and one ENABLED LED. (See Figure 1-3 and Table 1-1.)

Figure 1-3 PA-H LEDs-Horizontal Orientation

After system initialization, the enabled LED goes on to indicate that the port adapter has been enabled for operation.

The following conditions must be met before the PA-H is enabled:

The PA-H is correctly connected and receiving power.

A valid system software image for the PA-H has been downloaded successfully.

The system recognizes the PA-H or PA-H-equipped VIP or Catalyst RSM/VIP2.

If any of the above conditions are not met, or if the initialization fails for other reasons, the enabled LED does not go on.

Cables, Connectors, and Pinouts

Two types of cables are available for use with the PA-H: the HSSI interface cable, which is used to connect your router to an external DSU (and HSSI network), and a null modem cable, which is used to connect two routers back-to-back. Both HSSI cables are available only from Cisco Systems and conform to EIA/TIA-612 and EIA/TIA-613 specifications.

HSSI Interface Cable

The HSSI cable (CAB-HSI1) connects the PA-H with the external DSU. The HSSI cable is 10 feet (3.05 meters) long. The maximum HSSI cable length allowed is 50 feet (15.24 meters). Figure 1-4 shows the HSSI cable and the 50-pin connector used at each end of the HSSI cable. For connection instructions, see "Removing and Installing Port Adapters." Table 1-2 lists the pinouts.

HSSI Null Modem Cable

The null modem cable (CAB-HNUL) can connect two routers directly back-to-back. The null modem cable is 10 feet (3.05 meters) long. Figure 1-5 shows the null modem cable. The maximum null modem cable length allowed is 50 feet (15.24 meters). The two routers must be in the same location, and can be two Cisco 7000 series routers, two Cisco 7500 series routers, two Cisco 7200 series routers, two Cisco 7200 VXR routers, two Cisco uBR7200 series routers, two Cisco 7201 routers, two Cisco 7301 routers, two Cisco 7401ASR routers, two Cisco 7304 routers, or one of each. Using a null modem connection you can verify the operation of the HSSI, or you can link the routers directly in order to build a larger node.

Figure 1-5 Null Modem Cable and Connectors

The null modem cable uses the same 50-pin connectors as the HSSI cable, but uses the pinouts listed in Table 1-3. For connection instructions, see "Removing and Installing Port Adapters."

Catalyst RSM/VIP2 Slot Numbering

The Catalyst RSM/VIP2 can be installed in any slot in a Catalyst 5000 family switch except the top slots, which contain the supervisor engine modules. The Catalyst RSM/VIP2 does not use interface processor slot numbering; therefore, the slots in which it is installed are not numbered. A port adapter can be installed into either port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. Figure 1-6 shows a Catalyst RSM/VIP2 with two port adapters installed.


Note The Catalyst 5500 switch has 13 slots. Slot 1 is reserved for the supervisor engine module. If a redundant supervisor engine module is used, it must go in slot 2; otherwise, slot 2 can be used for other modules. Slot 13 is a dedicated slot, reserved for the ATM Switch Processor (ASP) module. Refer to the Catalyst 5000 Series Route Switch Module Installation and Configuration Note for any additional slot restrictions for the Catalyst RSM/VIP2.

Identifying Interface Addresses

This section describes how to identify the interface address for the PA-H in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a PA-H installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-H installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move a VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot.


Note Interface ports are numbered from left to right starting with 0.


The following subsections describe the interface address formats for supported platforms:

1 Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.

2 Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).


Catalyst RSM/VIP2 Interface Addresses

In Catalyst 5000 family switches, the Catalyst RSM/VIP2 can be installed in any slot except the top slots, which contain the supervisor engine modules. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch does not use interface processor slot numbering; therefore, the slots in which it is installed are not numbered. A port adapter can be installed into either port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. See Figure 1-6.

The interface address is composed of a two-part number in the format port-adapter-slot number/interface-port number. See Table 1-4. For example, if a single-port PA-H is installed in port adapter slot 1 of a Catalyst RSM/VIP2 in a Catalyst 5000 family switch, the interface address would be 1/0.

Catalyst 6000 Family FlexWAN Module Interface Addresses

In Catalyst 6000 family switches, the Catalyst 6000 family FlexWAN module can be installed in module slots 2 through 13 (depending on the number of slots in the router). Slot 1 is reserved for the supervisor engine. A port adapter can be installed into either port adapter bay 0 or bay 1 on a FlexWAN module. See Figure 1-7.

The interface address is composed of a three-part number in the format module-number/port-adapter-bay-number/interface-port-number. See Table 1-4.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-H is a single-port port adapter, therefore the port is always 0.

For example, if the FlexWAN module is inserted in module slot 3, then the interface address of the port adapter is 3/0/0 (module slot 3, port adapter bay 0, and interface 0). If the port adapter is in port adapter bay 1 on the FlexWAN module, this same interface address would be numbered 3/1/0. If you remove the FlexWAN module with the port adapter from module slot 3 and install it in module slot 6, the interface address becomes 6/0/0.


Note The FlexWAN module physical port address begins with slot 0, which differs from the conventional Catalyst 6000 family port address, which begins with slot 1.


Cisco 7120 Router and Cisco 7140 Router Interface Addresses

In Cisco 7120 series router, port adapters are installed in port adapter slot 3. See Figure 1-8. In the Cisco 7140 series router, port adapters are installed in port adapter slot 4. See Figure 1-9.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed on a Cisco 7120 router, the interface address would be 3/0. If a single-port PA-H is installed on a Cisco 7140 router, the interface address would be 4/0.

Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses

In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-10.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed in slot 1of a Cisco 7200 series router, the interface address would be 1/0. If a single-port PA-H is installed in slot 4, the interface address would be 4/0.

Cisco uBR7200 Series Routers Interface Addresses

In the Cisco uBR7223 router, only one slot accepts port adapters and it is numbered slot 1.

In the Cisco uBR7246 router and Cisco uBR7246VXR router, port adapters can be installed in two port adapter slots (slot1 and slot 2). Slot 0 is always reserved for the I/O controller—if present. See Figure 1-11.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed in slot 1of a Cisco uBR7223 series router, the interface address would be 1/0. If the single-port PA-H is installed in slot 2 of a Cisco uBR7246 or Cisco uBR7246VXR router, the interface address would be 2/0.

Cisco 7201 Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed in a Cisco 7201 router, the interface address would be 1/0.

Cisco 7301 Router Interface Addresses

In the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-13.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed in a Cisco 7301 router, the interface address would be 1/0.

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

In the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-15.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface address would be 3/0.

Cisco 7401ASR Router Interface Addresses

In the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered slot 1. See Figure 1-16.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a single-port PA-H is installed on a Cisco 7401ASR router, the interface address would be 1/0.

Cisco 7000 Series Routers and Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7000 series routers and Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-17, and Figure 1-18.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-4.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-H is a single-port port adapter, therefore the port is always 0.

For example, if a single-port PA-H is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface address would be 3/1/0. If the PA-H is in port adapter slot 0 on the VIP, the same interface address would be 3/0/0.


Note Although the processor slots in the seven-slot Cisco 7507 and the thirteen-slot Cisco 7513 chassis are vertically oriented and those in the five-slot Cisco 7010 and Cisco 7505 chassis are horizontally oriented, all Cisco 7500 series routers use the same method for slot and port numbering.
