Chapter 2 Card Reference
15310E-CTX-K9 Card
2.2.1 System Cross-Connect
The 15310E-CTX-K9 card provides:
• 2016 VC12 ports. That is, 1008 VC-12 Cross-connections (1008X1008)
• 96 VC3 ports. That is, 48 VC-3 Cross-Connections (48X48)
• 128 VC4 ports. That is, 64 VC-4 Cross -Connections (64X64)
2.2.2 15310E-CTX-K9 Card Side Switches
The 15310E-CTX-K9 supports errorless side switches (less than a 50-ms impact to any traffic) when the
switch is initiated through software, through either a soft-reset or a software upgrade where there is no
FPGA or firmware upgrade. A side switch means switching from a 15310E-CTX-K9 on one side of the
shelf to the redundant 15310E-CTX-K9 on the other side of the shelf.
2.2.3 15310E-CTX-K9 Optical Interfaces
There are two PPM (SFP) slots on the 15310E-CTX-K9 faceplate to provide optical interfaces. (PPM is
the graphical user interface term for SFP.) Each slot can contain a one-port PPM. Cisco-qualified PPMs
can be single-rate (STM1, STM4, or STM16) or multirate (STM1/STM4). Single-rate PPMs are
autoprovisioned when they are installed, but multirate PPMs must be provisioned. This behavior can be
controlled by NE defaults.
Note To provision, edit, or delete PPM ports, refer to the “Change Port Settings” chapter in the
Cisco ONS 15310-MA SDH Procedure Guide. For more information about PPM/SFP hardware, see the
“2.8 SFP Modules” section on page 2-19.
Note CTX-2500 only supports STM1-E Electrical SFP.
2.2.4 15310E-CTX-K9 Card-Level Indicators
The 15310E-CTX-K9 card has four card-level LEDs, described in Table 2 -3.
Table 2-3 15310E-CTX-K9 Card-Level Indicators
Card-Level LEDs Description
FAIL LED (Red) The red FAIL LED indicates that the card processor is not ready or that a
catastrophic software failure occurred on the card. As part of the boot
sequence, the FAIL LED turns on and flashes until the software deems the
card operational.
