Configuring Switches in a Stack

3.The management election process uses the following precedence to assign a management switch:

a.Previously assigned/elected management switch

b.Management assigned priority (values 1–15)

c.Hardware preference level

d.Highest MAC Address

Recommended Procedures for New and Existing Stacks

Important

The following procedures assume that all switches have a clean configuration from manufacturing. When adding a new switch to an already running stack, it is also assumed that the new switch is using the same firmware image version as other switches in the stack.

Installing a New Stackable System of Up to Eight Switches

Use the following procedure to install a new stack of up to eight switches out of the box. Before applying power, make all physical connections with the stack cables as described in “Connecting Stacking Cables” on page 3‐11.

1.Once all of the stack cables have been connected, individually power on each switch from top to bottom (connecting power to a switch is described in “Connecting AC and RPS‐SYS Power” on page 3‐16).

If the switches are powered on almost simultaneously, the system will automatically select the first one that powers up as the Master switch and the others as Member switches. The switches are assigned unit IDs in the order that they become fully operational.

You can control the unit ID assignment according to the physical position in a stack. When you power up each switch and allow it to become fully operational before applying power to the next switch, the first one becomes the Manager and all the next switches will join that stack (regardless of Priority, Firmware Revision, or MAC Address). The switches are assigned unit IDs in the order that you power on each switch.

Note: Once switch IDs are assigned, they are persistent and will be retained during a power cycle to any or all of the switches.

2.(Optional) If desired, change the management switch using the set switch movemanagement command as described in the SecureStack A2 Configuration Guide.

A2H124-24FX specifications

Enterasys Networks A2H124-24FX is a high-performance network switch designed to meet the demands of modern data centers and enterprise environments. This switch exemplifies the blend of reliability, scalability, and advanced features that enterprises require to ensure seamless connectivity and data management.

One of the main features of the A2H124-24FX is its 24 Fast Ethernet (10/100) ports. These ports provide a robust foundation for connecting various devices within a network, making it ideal for workplaces that require extensive connectivity options. Additionally, the switch supports up to 4 Gigabit SFP (Small Form-factor Pluggable) uplink ports, which facilitate high-speed connections to backbone switches or routers, catering to bandwidth-intensive applications.

Another significant characteristic of the A2H124-24FX is its support for Power over Ethernet (PoE). This technology enables the switch to deliver power to connected devices such as IP phones, wireless access points, and security cameras through the same Ethernet cable that transmits data. This feature not only reduces the need for additional power supplies but also streamlines installation processes, reducing overall operational costs.

Security is a paramount concern for any enterprise network, and the A2H124-24FX addresses this through various advanced security features. It includes support for IEEE 802.1X Network Access Control, which ensures that only authenticated users can access the network. Additionally, it provides features such as MAC address filtering and VLAN support to segment network traffic and enhance overall security.

In terms of management, the Enterasys Networks A2H124-24FX is equipped with a user-friendly interface that allows network administrators to configure and monitor the switch effortlessly. It supports both CLI (Command Line Interface) and web-based management, providing flexibility depending on user preference.

This switch also supports advanced Layer 2 and Layer 3 capabilities, including Quality of Service (QoS) features that help prioritize traffic, ensuring that critical applications receive the necessary bandwidth for optimal performance.

In conclusion, the Enterasys Networks A2H124-24FX combines functionality, security, and ease of management, making it an ideal choice for businesses looking to enhance their network infrastructure. Its robust features and reliable performance can effectively support the complex demands of modern networking environments.
