Cisco ASR 9000 SIP-700 Overview
Cisco ASR 9000 SIP-700 Overview
There are two types of Cisco ASR 9000 SIP-700 available; A9K-SIP-700 and A9K-SIP-700-8G.
• A9K-SIP-700 supports 4 GB of memory.
• A9K-SIP-700-8G supports 8 GB of memory.
Both types of Cisco ASR 9000 SIP-700 are identical in appearance and can be identified by the PID located
on the faceplate of the SIP
The following sections describe the Cisco ASR 9000 SIP-700:

SPA Interface Addresses on the Cisco ASR 9000 SIP-700
A Cisco ASR 9000 Series Aggregation Services Router identifies a SPA interface address by its rack number,
SIP slot number, SPA subslot, and port number on the SPA, in the format rack/slot/subslot/port . Subslots
and ports are numbered starting from 0, so each Cisco ASR 9000 SIP-700 has two subslots 0 (left) and 1
(right). For example, the interface addresses of a 2-port SPA located in the second SIP subslot, where the SIP
is inserted into router line card slot 3 in rack 0 are 0/3/1/0 and 0/3/1/1. The following figure shows the slot,
subslot, and port locations for the 2-Port Channelized OC-12/DS0 SPA on a Cisco ASR 9006 6-slot chassis.

CHAPTER 2
Overview: Cisco ASR 9000 Series Router Shared
Port Adapters
This chapter describes the shared port adapters (SPAs) that are supported on the Cisco ASR 9000 Series
Aggregation Services Router and contains the following sections:
• SPA Summary, on page 9
• 2-Port Channelized OC-12/DS0 SPA Overview, on page 12
• 1-Port Channelized STM-16/OC-48 SPA Overview, on page 14
The minimum FPD version for the SPA-4XT-Serial SPA is 1.04. Refer to the "Upgrading FPD" chapter in the System
Management Configuration Guide for Cisco ASR 9000 Series Routers for information on how to verify image versions
and how to perform an upgrade for SPA FPD images.
Checking Hardware and Software Compatibility
To check the minimum software requirements of Cisco IOS XR software with the hardware installed on your
router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether SIPs or
SPAs within a system are compatible, but it does provide the minimum Cisco IOS XR requirements for
individual hardware modules or components.

2-Port Channelized OC-12/DS0 SPA Overview
The 2-Port Channelized OC-12/DS0 SPA is a double-height SPA that provides Synchronous Optical NETwork
(SONET) network connectivity with a bandwidth of 622.08 Mbps.
The following sections describe the 2-Port Channelized OC-12/DS0 SPA:
2-Port Channelized OC-12/DS0 SPA LEDs
The 2-Port Channelized OC-12/DS0 SPA has three types of LEDs. There are two LEDs for each port on the
SPA, and one STATUS LED. The following figure shows an example of these LEDs on a SPA.
The framer processes incoming and outgoing SONET frames. The framer operates at OC-12c/STM-4 line
rates (622.08 Mbps). Packet data is transported with a user-configured encapsulation (such as Point-to-Point
Protocol [PPP]) and mapped into the STS-12c/STM-4 frame. The main operational mode of the framer is
OC-12, where each one of the 12 Paths can carry a DS3 and each DS3 can carry 28 DS1s.
The 2-Port Channelized OC-12/DS0 SPA interface is compliant with ANSI and Telco standards.
2-Port Channelized OC-12/DS0 SPA SFP Optical Transceiver Modules and
Cables
The 2-Port Channelized OC-12/DS0 SPA uses a small form-factor pluggable (SFP) optical transceiver module
installed in each port for SONET single-mode and multimode optical fiber connection. (See the following
figure.)
Cisco Systems qualifies the optics that are approved for use with its SPAs. The 2-Port Channelized OC-12/DS0
SPA supports the following types of optical transceiver modules:
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal diameter is
approximately 10/125 microns.)
Use single-mode (for intermediate or long-reach configurations) or multimode optical fiber cable to connect
your router to a network or to connect two 2-Port Channelized OC-12/DS0 SPA -equipped routers back to
back.
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.
1-Port Channelized STM-16/OC-48 SPA Overview
The following sections describe the 1-Port Channelized STM-16/OC-48 SPA:
1-Port Channelized STM-16/OC-48 SPA LEDs
The 1-Port Channelized STM-16/OC-48 SPA has two types of LEDs: an A/L LED for the port and a STATUS
LED, as shown in the following figure.
Cisco ASR 9000 Series Aggregation Services Router SIP and SPA Hardware Installation Guide
14
Overview: Cisco ASR 9000 Series Router Shared Port Adapters
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-48/STM-16
line rates (2.488 Gbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]) and
is mapped into the STS-48/STM-16 frame. HDLC and Frame-Relay are also supported. The main operational
mode of the framer is OC-48, where each one of the 48 Paths can carry a DS3 and each DS3 can carry 28
DS1s.
Cisco ASR 9000 Series Aggregation Services Router SIP and SPA Hardware Installation Guide
15
Overview: Cisco ASR 9000 Series Router Shared Port Adapters
1-Port Channelized STM-16/OC-48 SPA Cables and Connectors
The 1-Port Channelized STM-16/OC-48 SPA interface is compliant with RFC 1619, PPP over SONET/SDH,
and RFC 1662, PPP in HDLC-like Framing. The 1-Port Channelized STM-16/OC-48 SPA also provides
support for SNMP v1 agent (RFC 1155–1157), and Management Information Base (MIB) II (RFC 1213).
1-Port Channelized STM-16/OC-48 SPA Cables and Connectors
The 1-Port Channelized STM-16/OC-48 SPA uses a small form-factor pluggable (SFP) optical transceiver
module installed in the port for SONET and SDH single-mode and multimode optical fiber connection (see
the following figure).
Figure 9: SFP Optics Module
The SFP optical transceiver modules used with the 1-Port Channelized STM-16/OC-48 SPA provide the
following optical fiber options:
• Multimode—2.488-Gbps, OC-48/STM-16 optical fiber (SONET STS-48 or SDH STM-16)
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
• Single-mode—2.488-Gbps, OC-48/STM-16 optical fiber (SONET STS-48 or SDH STM-16)
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal diameter is
approximately 10/125 microns.)
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see the
figure below) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to connect
your router to a network or to connect two 1-Port Channelized STM-16/OC-48 SPA-equipped routers back
to back.
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.
