Installing the Switch on a Flat Surface When installing the switch on a flat surface, the installation of the rubber feet is recommended to prevent the switch from sliding on a flat surface. Installing the rubber feet is optional if you are installing the switch in a rack. To install the rubber feet, proceed to “Installing the Rubber Feet” instructions below. For instructions to rack mount the switch, proceed to “Rack Mounting the Switch” on page 3‐10. Installing the Rubber Feet To install the rubber feet, refer to Figure Place the switch on its back on a sturdy flat surface to gain access to the bottom of the chassis. Remove the four rubber feet from their plastic bag in the shipping box. Locate the four marked locations on the bottom four corners of the chassis. Remove the protective strip from the back of one rubber foot and position it on a marked location and press firmly into place. Repeat this procedure to install the remaining three rubber feet in the other three locations.

Note: To ensure proper ventilation and prevent overheating, leave a minimum clearance space of 5.1 cm (2.0 in.) at the left, right, and rear of the switch. Warning: Before rack-mounting the switch, ensure that the rack can support it without compromising stability.
Connecting Stacking Cables The stack of switches can be connected in a closed loop or daisy chained. In a closed loop all the switches are connected in sequence and the last switch in the stack is connected back to the first switch. In a daisy chain configuration the cable that would return the connection back to the first switch in a closed loop is not installed. The advantage of the closed loop is redundancy, this configuration eliminates any single point of failure. Up to eight switches can be stacked together and connected by standard UTP Category 5 or better cables. The stacking cables allow the entire stack to operate with a single IP address.

Configuring Switches in a Stack The information in the following sections is important to understand A2 switch operation and installations in a stack installation. About SecureStack A2 Switch Operation in a Stack The SecureStack A2 products are stackable switches that can be adapted and scaled to help meet your network needs. These switches provide a management platform and uplink to a network backbone for a stacked group of up to eight A2 switches. Once installed in a stack, the switches behave and perform as a single switch. As such, you can start with a single switch and add more switches as your network expands. You can also mix different products in the same family in a single stack to provide a desired combination of port types and functions to match the requirements of individual applications. In all cases, a stack of switches performs as one large product, and is managed as a single network entity. When switches are installed and connected as described back in “Connecting Stacking Cables” on page 3‐11, the following occurs during initialization: • The switch that will manage the stack is automatically established and is referred to as the Manager switch. • All other switches are established as Member switches in the stack. • The hierarchy of the switches that will assume the function of backup manager is also determined in case the current manager malfunctions, is powered down, or is disconnected from the stack. • The Console port on the manager switch remains active for out‐of‐band (local) switch management, but the Console port on each member switch is deactivated. This enables you to set the IP address and system password using a single Console port. ...
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.
• Use clear config to clear config parameters without clearing stack switch IDs. This command WILL NOT clear stack parameters and avoids the process of re-numbering the stack. • Use clear config all when it is necessary to clear all config parameters, including stack switch IDs and switch priority values.
Note: If the CPU LED illuminates solid red, there was a critical failure. For more information about the LED indications and troubleshooting, refer to additional help, contact Enterasys Networks. Refer to details If the switch is a standalone switch, it will take approximately 30 seconds for the switch to start up.

Á RPS coverplate Retaining screws to fasten plate Caution: To prevent damaging the switch, DO NOT connect a Power over Ethernet-compliant Redundant Power System (C2RPS-POE) to the redundant power supply connector. The switch is only compatible with the SecureStack C2RPS-SYS redundant power supply system.
Stack Initialization Overview When you install and connect all the stacking cables to the switches in the stack before applying power to the switches, the following occurs: • The switch that will manage (Manager) the stack is automatically established with all other switches established as Member switches in the stack. When the switches complete their initializations, one of the switches in the stack will illuminate its Manager LED, indicating that it is the stack Manager. The Manager LED on each Member switch will be off. • The hierarchy of the switches that will function as backup Manager is also determined in case the current Manager malfunctions, is powered down, or is disconnected from the stack. • The Console port on each Member switch will provide only the unit number. Only the Console port on the Manager switch is active and provide a CLI for out‐of band configuration to set the IP address, password, and other settings. Once you know which switch is the Manager, proceed to “Connecting to Console Port for Local Management” on page 3‐20. Connecting AC and RPS-SYS Power SecureStack A2 Installation Guide 3-19...
Note: When switches are connected in a stack configuration and all stacking cables are connected before powering up the switches, one switch in the stack will be automatically designated as the Manager of the stack and its Console port will remain active. All other switches will become Member switches and their Console ports will be deactivated.
