Information About the SCE Platform
The Cisco SCE8000 10GBE is a transparent element with 10GBE links service throughput (Figure 2-1).
It can be installed inline in the network where the entire traffic passes through it or in receive-only mode
where it receives replication of the traffic through SPAN ports or optical splitters.
Figure 2-1 Cisco SCE8000 Platform
The Cisco SCE8000 supports the following network insertion models:
•single appliance (inline)
•single appliance (receive-only)
•cascade configuration
•MGSCP configuration
The Cisco SCE8000 platform is a 4-slot chassis hosting the following modules:
•One or two Service Control Modules (SCE8000-SCM-E) that each contain special purpose fast path
chipset, traffic processors and control processor.
•One SPA Interface Processor card (SCE8000-SIP) that holds up to four SPA 10GBE interface
modules.
•One optional optical bypass module hosting panel that holds up to two optical bypass modules.
In addition, the Cisco SCE8000 chassis contains two power supply modules in a 1+1 configuration, as
well as a fan tray module.

System Power •Steady green — Installed power supplies are functioning normally.
•Steady amber — Only one power supply is functioning normally.
•Unlit — No power from either power supply.
On a slave SCE8000-SMC_E module (in the second slot), this LED is always off.

Introduction to SIPs and SPAs
Introduction to SIPs and SPAs
SIPs and SPAs are a new carrier card and port adapter architecture used to increase modularity,
flexibility, and density for network connectivity. This section describes the SIPs and SPAs and provides
some guidelines for their use.
•SPA Interface Processors, page 2-5
•Specifying the SIP Subslot Location for a SPA, page 2-5
•Shared Port Adapters, page 2-6
•Modular Optics, page 2-6
•XFP Connections, page 2-7
SPA Interface Processors
The SIP module supported by the Cisco SCE8000 chassis is the SCE8000-SIP.
The following list describes some of the general characteristics of a SIP:
•A SIP is a carrier card that inserts into a slot in the chassis like a line card. It provides no network
connectivity on its own.
•A SIP contains one or more subslots (bays), which are used to house one or more SPAs. The SPA
provides interface ports for network connectivity.
•During normal operation the SIP should reside in the SCE8000 chassis fully populated either with
functional SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty
subslots.
Specifying the SIP Subslot Location for a SPA
Cisco SCE8000-SIP subslots begin their numbering with “0” and have a horizontal orientation.
Figure 2-3 shows the subslot numbering for the Cisco SCE8000-SIP.
The Cisco SCE8000-SIP supports four subslots for the installation of SPAs, as follows:
•SIP subslot 0—Top–left subslot
•SIP subslot 1—Top–right subslot
•SIP subslot 2—Bottom–left subslot
•SIP subslot 3—Bottom–right subslot

Introduction to SIPs and SPAs
Shared Port Adapters
The SPA supported by the Cisco SCE8000-SIP is the 1-Port 10-Gigabit Ethernet SPA,
SPA-1X10GE-L-V2
The following list describes some of the general characteristics of a SPA:
•A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card
to provide network connectivity and increased interface port density. The Cisco SCE8000-SIP can
hold up to four SPAs.
Since the interfaces are connected in subscriber/network pairs, either two or four SPAs must be
installed.
•The supported SPA is a single-height SPAs, which inserts into one SIP subslot. (See Figure 2-4.)
Figure 2-4 Single-Height SPA Size
•Each SPA provides a one 10GBE port, which is the interface to either subscriber or network traffic.
These interfaces can be individually configured using the Cisco command-line interface (CLI).
•Either a blank filler plate or a functional SPA should reside in every subslot of an SIP during normal
operation to maintain cooling integrity. Blank filler plates are available in single-height form only.
Since the interfaces are connected in subscriber/network pairs, the SCE8000-SIP must be either
fully populated or have both the bottom bays covered with blank filler plates.
Modular Optics
The SPAs implement 10GBE small form-factor pluggable (XFP) optical transceivers to provide network
connectivity (Figure 2-5). An XFP module is a transceiver device that mounts into the front panel to
provide network connectivity.
Note It is highly recommended only to use the XFP modules listed as supported in this document. Use of
unsupported or unqualified XFP modules may affect reliability or operation.

Figure 2-5 10GBE Small Form-factor Pluggable (XFP0)
The interface connector on the 1-Port 10-Gigabit Ethernet SPA is a fiber optic receiver that supports one
XFP.
The types of optics modules that have been qualified for use with the 1-Port 10-Gigabit Ethernet SPA on
the Cisco SCE8000 platform are as follows:
•XFP-10GLR-OC192SR
•XFP-10GER-OC192IR
•XFP-10GZR-OC192LR
•XFP-10G-MM-SR
XFP Connections
The qualified XFPs include an optical transmitter and receiver pair integrated with Clock and Data
Recovery (CDR) integrated circuits. The XFPs provide high-speed serial links at 10.3125 Gbps on single
mode fibers. Table 2-4 lists the XFP port cabling specifications.
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 laser, enabling data transmission over fiber through an LC connector. The
receive side recovers and retimes the 10 Gbps optical data stream from a photo detector trans impedance
amplifier and passes it to an output driver.
See the label on the XFP for technology type and model.
XFP dimensions are:
•Height 12.5 mm
•Width 18.35 mm
•Length 71.1mm
The XFP operating temperature range is 0°C to 70°C.

single-height 1-Port 10GBE SPA interface modules, but in the Cisco SCE8000, it must be configured
with either two 1-Port 10GBE SPAs (in the top two subslots) or four 1-Port 10GBE SPAs, to provide
interfaces for either one or two complete traffic links. Figure 2-6 provides an illustration of the SPA
module and Table 2-6 lists the SPA module ports and Table 2-7 lists the SPA module LEDs.

Chapter 2 Introduction to the Cisco SCE8000 10GBE Platform
The Cisco SCE8000 Optical Bypass
The Cisco SCE8000-SIP module already includes an internal electrical bypass, but it is strongly
recommended to use the optical bypass module for addressing the following scenarios:
•During platform reboot (SW reload)—If the external bypass module is not used, there is a 10-second
period (at most) during which the link is forced down (cutoff functionality).
•During a power failure —The Cisco SCE8000 has two power supplies. A power failure occurs only
when both of them fail.
In a case where the Cisco SCE8000 platform must be replaced, it is possible to remove the bypass
modules from the SCE8000 chassis without disconnecting them from the network and then reinstall them
in the new SCE platform, so that traffic links are preserved even in a case of complete failure and
replacement of the Cisco SCE8000 platform. (See Replacing the Optical Bypass Module without
Disrupting Traffic on the Link, page 9-27.)
Optical Bypass Functionality
The optical bypass module is connected bump-in-the-wire in the 10-GBE link. It is then connected to the
Cisco SCE8000 platform with two types of connections:
•10GBE optical connections for data link traffic — 10 GBE connections from the optical bypass
module to one pair of the 10GBE SPA ports.
•Control connection — Connection to the RJ-11 External Bypass connector on the SCE8000-SCM,
so the optical bypass is activated if the Cisco SCE8000 platform fails.
Optical Bypass Module Connectivity
The optical bypass module functions as follows:
•Under normal conditions, the bypass module directs traffic to flow via the Cisco SCE8000
(Figure 2-7).
•Under failure conditions, the optical bypass shortcuts the interfaces that are connected to the traffic
link, and all traffic flows through the optical bypass module, bypassing the SCE platform
(Figure 2-7).
