Flexible PLIM Summary

The Cisco CRS-3 Flexible PLIM supports SPAs and has four SPA bays available. The Cisco CRS-3 Flexible PLIM has six integrated, 10 GE ports. These ports support multiple framing options, including WAN, LAN, and OTN. These ports also support Tunable DWDM optics, turning the 6-ports into 10 GE IP over DWDM (IPoDWDM) interfaces.

The PLIM mates with its associated modular services card (MSC) through the chassis midplane. Each available SPA provides different interface types and port densities. For a description of the SPAs supported on the Cisco CRS-3 Flexible PLIM, see Chapter 4 "Overview: Cisco CRS Shared Port Adapters."

Table 3-1 shows a summary description of the PLIM supported on the Cisco CRS-3 router.

Table 3-2 describes the Cisco CRS-3 Flexible PLIM LEDs.

Table 3-2 Cisco CRS-3 Flexible PLIM LED 

LED Label	Color	State	Meaning
PLIM Status LED	Green	On	The PLIM is powered on and operational.
	Amber	On	The PLIM has a problem or is disabled by software.
	Off	Off	The PLIM is powered off.
Port Status LED	Green	On	The port is enabled by software and there is a valid link.
	Amber	On	The port is disabled by software or there is a problem with the link.
	Off	Off	The PLIM is powered off.

Physical Specifications

Table 3-3 shows the Cisco CRS-3 Flexible PLIM physical specifications.

Identifying Slots and Subslots for PLIMs and SPAs

The following sections describe PLIM, SPA, and interface numbering:

•PLIM Slot Locations on the Cisco CRS-3 Router

•SPA Slot Numbering on the Cisco CRS-3 Flexible PLIM

•SPA Interface Addresses on PLIMs

PLIM Slot Locations on the Cisco CRS-3 Router

A PLIM can be installed in slots 0 through 15 on the Cisco CRS-3 router 16-slot line card chassis and in slots 0 through 7 on the Cisco CRS-3 router 8-slot line card chassis. Figure 3-2 and Figure 3-3 show the slot numbering on the front (PLIM side) of the line card chassis.

Figure 3-2 16-Slot Line Card Chassis Slot Numbers—Front (PLIM) View

Figure 3-3 8-Slot Line Card Chassis Slot Numbers—Front (PLIM) View

For additional information about the slot locations of PLIMs and their associated modular services cards (MSCs), see Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description or Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description.

SPA Slot Numbering on the Cisco CRS-3 Flexible PLIM

The Cisco CRS-3 Flexible PLIM accepts four single-width SPAs. Figure 3-4 shows a Cisco CRS-3 Flexible PLIM with two 4-Port OC-48c/STM-16 POS/RPR SPAs installed in subslots 1 and 3.

Figure 3-4 and Figure 3-5 illustrate the SPA subslot locations on the Cisco CRS-3 Flexible PLIM. The subslot labels are located inside the SPA subslot and are only visible when the SPA is not installed.

SPA Interface Addresses on PLIMs

SPAs in the Cisco CRS-3 Flexible PLIM running Cisco IOS XR Software Release 4.3.0 use an addressing format that specifies the physical location of the PLIM, SPA, and interface. The interface address format is rack/slot/subslot/port, where:

•rack—Specifies the rack number, 0 in a single-chassis system.

•slot—Specifies the slot number in which the Cisco CRS-3 Flexible PLIM is inserted:

–For the 8-slot line card chassis—0 through 7

–For the 16-slot line card chassis—0 through 15

•subslot—Specifies the slot in which the SPA is inserted—1 through 4

•port—Specifies the interface number that you want to select on the SPA:

–For the 1-Port OC-192c/STM-64 POS/RPR XFP SPA—0 is the only option

–For the 4-Port OC-48c/STM-16 POS/RPR SPA—0 through 3

–For the 8-Port Gigabit Ethernet (V2) SPA—0 through 7

Restrictions

Thermal restrictions:

4-slot chassis—No slot restrictions.

8-slot chassis—No slot restrictions.

16-slot chassis (for non-VE chassis)—The Cisco CRS-3 Flexible PLIM is a high powered PLIM. High powered PLIMs are confined to upper slots, but are allowed in lower slots only if another identical PLIM is installed directly above.

16-slot enhanced chassis—No slot restrictions.
