2 Introduction
The PRIMERGY BX600 Blade Server system is a modular server system that can
integrates up to 10 server modules, four IBP Modules (one IBP will be included in the base
enclosure, the other three are optional) and two Management Modules (MMB). The IBP
Module provides networking connectivity to PRIMERGY BX600 Blade Server. The
Management Modules provides a single point of control for the PRIMERGY BX600 Blade
Server.
The PRIMERGY BX600 Intellignent Blade Panel (IBP) Modules are 42-port devices that
are connected to servers through the mid-plane connectors located on PRIMERGY BX600
Blade Server middle plane. The device has 42 ports. The ports numeration starts from the
internal ports g1-g30 connected to server blades, and ports g31-g42 are the external ports
connecting the IBP Module to the network through the internal ports.
• 12 external RJ-45 connectors for 10/100/1000 Base-T copper ports (uplinks).
• 30 internal ports connected to servers through PRIMERGY BX600 Blade Server mid-plane
connector of a VHDM type.
The terminal connection to the device is provided through the MMB board only. No access
point is provided on the IBP Module front panel. For debugging and management purposes, a
UART bus of each IBP Module is connected to the MMB board. The MMB board can select for
management only one IBP at a time.
The IBP Module receives a power supply (12 V dc) through the mid-plane connector. A
four system LED indicates the IBP Module status (Power module,MMB-selected or not).
The following figure illustrates the PRIMERGY BX600:

2.1 Features of the IBP Module
The IBP provides a wide range of advanced performance-enhancing features. Multicast
filtering provides support for real-time network applications. Flow control eliminates the loss of
packets due to bottlenecks caused by port saturation. And broadcast storm suppression
prevents broadcast traffic storms from engulfing the network. Some of the management
features are briefly described below.
Head of Line Blocking
Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing
for the same egress port resources. HOL blocking queues packets, and the packets at the
head of the queue are forwarded before packets at the end of the queue.
