Checking Hardware and Software Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether the Cisco 7600 ES20 line cards within a system are compatible, but it does provide the minimum Cisco IOS requirements for individual hardware modules or components.

---

Note Access to this tool is limited to users with Cisco.com login accounts.

---

To access Software Advisor, click Login at Cisco.com, type "Software Advisor" in the SEARCH box, and click GO. Click the link for the Software Advisor tool.

Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

Identifying Slots and Subslots for the Cisco 7600 Series Ethernet Services 20G Line Cards

This section describes how to specify the physical location of a Cisco 7600 Series Ethernet Services 20G line cards on the Cisco 7600 series routers within the command-line interface (CLI) to configure or monitor those devices.

Specifying the Slot Location for a Cisco 7600 Series Ethernet Services 20G Line Cards

The Cisco 7600 series routers support different chassis models, each of which supports a certain number of chassis slots.

---

Note The Cisco 7600 ES20 line cards are not supported with a Supervisor Engine 1, Supervisor Engine 1A, Supervisor Engine 2, or Supervisor Engine 720-3A.

---

For information about the chassis slots available in different Cisco 7600 series router models, see http://www.cisco.com/univercd/cc/td/doc/product/core/cis7600/hardware/cis_76xx/osr_over.htm.

Some commands allow you to display information about the Cisco 7600 ES20 line card itself, such as show module, show idprom module, show hw-module slot, and show diagbus. These commands require you to specify the chassis slot location where the Cisco 7600 ES20 line card that you want information about is installed.

For example, to display status and information about the Cisco 7600 ES20 line card installed in slot 6 of a Cisco 7609 router, enter the following command:

Router# show module 6

For more information about Cisco 7600 ES20 line card commands, see the "Command Summary for the Cisco 7600 Series Ethernet Services 20G Line Card " and the "Cisco 7600 Series Ethernet Services 20G Line Card Commands" chapters in the Cisco 7600 Series Router SIP, SSC, and SPA Software Configuration Guide .

---

Note The Cisco 7600 ES20 line card must be in a slot that provides two primary serial channels. Dual serial channels are not available in all slots of a 13-slot chassis. Dual fabric connectivity is supported in slots 9 to 13.

---

Cisco 7600-ES20-10G Line Card Slot, Bay, and Port Locations

The Cisco 7600-ES20-10G line card uses a slot/bay/port numbering scheme. The slot refers to whichever slot the line card occupies in the router. The bay number is always 0. The port number is either 0 or 1.

Executing the show interface command for a Cisco 7600-ES20-10G line card located in slot 4 of a Cisco 7600 series router chassis produces the following:

show interface TenGigabitEthernet4/0/0   (first interface)

show interface TenGigabitEthernet4/0/1   (second interface)

Cisco 7600-ES20-GE Line Card Slot, Bay, and Port Locations

The Cisco 7600-ES20-GE line card uses a <slot, bay, port> numbering scheme. The slot refers to whichever slot the line card occupies in the router. The bay number is always zero. The port number is zero through 19.

Executing the show interface command for a Cisco 7600-ES20-GE line card located in slot 6 of a Cisco 7600 series router chassis produces the following (only first six interfaces are shown):

show interface TenGigabitEthernet6/0/0 	(first interface)

show interface TenGigabitEthernet6/0/1   (second interface)

show interface TenGigabitEthernet6/0/2 	(third interface)

show interface TenGigabitEthernet6/0/3 	(fourth interface)

show interface TenGigabitEthernet6/0/4 	(fift interface)

show interface TenGigabitEthernet6/0/5 	(sixth interface)

For more information about Cisco 7600 ES20 line card commands, see the "Command Summary for the Cisco 7600 ES20 Line Cards " and the "Cisco 7600 ES20 Line Card Commands" chapters in the Cisco 7600 Series Router SIP, SSC, and SPA Software Configuration Guide .

Cisco 7600-ES20-10G Cables and Connectors

The Cisco 7600-ES20-10G line card supports the XFP-10GLR-OC192SR and XFP-10GER-OC192IR XFP modules.

The XFP-10GLR-OC192SR and XFP-10GER-OC192IR XFPs modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits.

The XFP modules provide high-speed serial links at the following rates: 9.95 Gbps (OC-192) and 10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber (SMF). The transmit side recovers and retimes the 10-Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm or 1550-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo-detector transimpedance amplifier and passes it to an output driver.

See the label on the XFP module for technology type and model.

•XFP module dimensions are:

•Height: 12.5 mm

•Width: 18.35 mm

•Length: 71.1mm

The XFP module temperature range is 0°C to 70°C.

Cisco 7600-ES20-GE Line Card Cables and Connectors

The Cisco 7600-ES20-GE line card uses a small form-factor pluggable (SFP) optical transceiver module installed in each GE SFP port.

Figure 2-5 SFP Optics Module

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between the two of them.

---

Note When shorter distances of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver.

---

Table 2-10 provides cabling specifications for the SFP modules that can be installed on the Cisco 7600-ES20-GE line card. Note that all SFP ports have LC-type connectors.

1 Multimode fiber (MMF) only. 2 A mode-conditioning patch cord is required. When using the SFP-GE-L with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the SFP module and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 ft (300 m). We do not recommend using the SFP-GE-L and MMF with no patch cord for very short link distance (tens of meters). The result could be an elevated bit error rate (BER). 3 Dispersion-shifted single-mode fiber-optic cable.
