The modules listed in Table B.1 are described in the following sections.
The EP Management Module

Hardware Overview

EP ASICs
EP module ports are managed by the following custom ASICs:
• Integrated Gigabit Controllers (IGCs) – Ethernet packet controllers for Gigabit ports. Each Gigabit Ethernet
module contains two IGCs.
• Integrated Packet Controllers (IPCs) – Ethernet packet controllers for 10/100 ports. Each 10/100 Ethernet
module contains two IPCs.
These custom ASICs perform address lookup, data formatting and data movement for Ethernet packets. The
Gigabit Ethernet modules use IGCs. The 10/100 modules use IPCs.
Each Gigabit Ethernet management or forwarding module has two IGCs.
• IGC 1 manages ports 1 – 4 on the module.
• IGC 2 manages ports 5 – 8 on the module.
Each 10/100 forwarding module has two IPCs:
• IPC 1 manages ports 1 – 24 on the module.
• IPC 2 manages ports 25 – 48 on the module.
Generally, you do not need to know which IGC or IPC is managing a port. However, the information is useful for a
few features such as port monitoring. The documentation repeats the IGC and IPC port mapping information
where needed.
Serial Management Interface
On management modules, the serial management interface enables you to configure and manage the device
using a third-party terminal emulation application on a directly connected PC. A straight-through EIA/TIA DB-9
serial cable (M/F) is shipped with the device.
Reset Button
On management modules, the reset button allows you to restart the system. The button is recessed to prevent it
from being pushed accidentally.
