Overview: Cisco CRS-3 Flexible PLIM

This chapter describes the flexible PLIM that is supported on the Cisco CRS-3 router and contains the following sections:

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 Chapter4, “Overview: Cisco CRS Shared Port Adapters”

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

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

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 . Both documents are available online from the specific chassis hardware documentation links at the following URL:

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 and high-powered 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. Cisco CRS high-powered PLIMs are subject to slot placement restrictions on the legacy 16-slot chassis. The following error message appears if these restrictions are not followed:

PLATFORM-SHELFMGRV2-4-HIGH_POWERED_PLIM_NOT_POWERED_ON_IN_LOWER_BAY

The following PLIMs are high-powered PLIMs:

CRS-CGSE-PLIM—Cisco CRS Carrier Grade Services Engine (CGSE) PLIM

1OC768-DPSK/C-O—Cisco CRS-1 1xOC768 (C-band) DPSK+ DWDM PLIM (Offset TDC)

6-10GE-WLO-FLEX—Cisco CRS Flexible PLIM

4-40GE-L/OTN—Cisco CRS 4-Port 40 GE LAN/OTN Interface Module

The rules for placement of high-powered PLIMs are:

a. A FLEX PLIM (6-10GE-WLO-FLEX) in the lower shelf cannot be placed under a CGSE PLIM directly above in the upper shelf.

b. High-powered PLIMs may only be placed in lower slots if a high-powered PLIM is in the slot directly above or if the slot above is empty.

  • 16-slot enhanced chassis—No slot restrictions.
