Problem Description

In service support for the 15600-CXC is limited to the following SONET SW releases R1.0.0, R1.1.0, R1.1.1, R1.1.2, R1.1.3, R1.3.1 and the SDH SW release R1.4.0. Support for the 15600-CXC in the R5.0.0 SONET SW release will be limited to allowing upgrades from the 15600-CXC to the 15600-SSXC. The 15600-SSXC is the only cross connect supported by R5.0.0. While the majority of customers have moved to the SSXC, the Workaround/Solution section of this notice provides a means for and remaining customer(s) wishing to do so.

Note: The R1.4.0 SDH SW does not currently have an upgrade plan that supports the 15600-SSXC(=) or its features.

Background

The 15600-CXC uses off-the-shelf components that were available during its development. The 15600-SSXC uses a custom ASIC developed by Cisco specifically for supporting future product features. Extended support for the 15600-CXC is currently planned only for SDH customers until new SDH SW that supports the 15600-SSXC is released. At that time SDH installations will have the same HW and SW support constraints.

Problem Symptoms

There is a HW/SW compatability constraint. R5.0.0 will only support the 15600-SSXC which affects all SONET customers. R5.0.0 and the 15600-SSXC are required for all future release features. The 15600-CXC is supported on all prior releases of SONET SW (R1.0.0, R1.1.0, R1.1.1, R1.1.2, R1.1.3 and R1.3.1) and for the current SDH SW release (R1.4.0).

Workaround/Solution

Customers currently using the 15600-CXC may request replacement with the 15600-SSXC by contacting the account team via e-mail.

Lead times for the 15600-SSXC have been up to 20 weeks in some cases. Please factor this in to your upgrade plans when considering deployment of the R5.0.0 CTC or later Releases.

How To Identify Hardware Levels

Hardware identification can be done by the Product ID (PID). Boards that are included in the upgrade have the PID of 15600-CXC. For active systems that are upgrading to the 15600-SSXC verification of the SW load on the 15600-TSC can be done using CTM. The system upgrade then needs to follow the appropriate upgrade procedure.
