For which platform family is the JD557A intended?

The JD557A is intended for HPE Networking Comware MSR platforms, as indicated by its full model name, HPE Networking Comware MSR 1-port Enhanced Serial SIC Module. This positions it as an expansion option specifically aligned with MSR routers that use the Comware software family.

How many serial ports are available on the JD557A module?

The JD557A module provides a single port, as indicated by the description 1-port Enhanced Serial SIC Module. This makes it suitable when a deployment requires one additional serial interface per module, allowing granular planning of serial connectivity on HPE Networking Comware MSR routers.

What role does the JD557A play in a router configuration?

The JD557A functions as a router interface module in the form of a Smart Interface Card that adds a 1-port enhanced serial connection. In a router configuration, it serves as an expansion component that increases serial connectivity on HPE Networking Comware MSR platforms without changing the base router hardware.

Is the JD557A suitable for modular serial connectivity planning?

Yes, the JD557A is suitable for modular serial connectivity planning because it is a 1-port Enhanced Serial SIC Module for HPE Networking Comware MSR routers. Its single-port design allows network teams to add serial connectivity in discrete increments aligned with specific link requirements.

Product overview

The HPE Networking Comware MSR 1-port Enhanced Serial SIC Module JD557A is a dedicated expansion option designed to add a single serial interface to compatible MSR platforms. As a 1-port enhanced serial Smart Interface Card module, it focuses on extending serial connectivity within existing network infrastructures. The module belongs to the router interface module category and is intended for environments that require an additional enhanced sync or async serial connection. Its design supports use in structured, managed networking deployments where serial lines remain part of the overall WAN or legacy integration strategy. This module is suitable for organizations standardizing on HPE Networking Comware MSR devices and needing a consistent approach to serial expansion. By providing a specific 1-port enhanced serial interface on a SIC form factor, the JD557A helps keep serial connectivity modular and clearly segmented within the routing architecture.

Best for

MSR serial expansion
Use this module when a HPE Networking Comware MSR platform requires an additional 1-port enhanced serial interface for integration into existing serial-based links.
Router interface module
Ideal as a router interface module where a single enhanced serial Smart Interface Card is needed to extend connectivity without changing the core router platform.
Legacy serial integration
Useful for environments that still rely on serial connectivity and need a dedicated 1-port enhanced serial SIC module to maintain or expand these links.
Standardized MSR deployments
Appropriate for standardized HPE Networking Comware MSR deployments where serial connectivity must be added using consistent 1-port enhanced serial SIC hardware.
Modular WAN design
Fits modular WAN designs that separate serial connectivity into discrete 1-port enhanced serial modules for easier planning and lifecycle management.
