Page 29: Installing The Switch On A Flat Surface
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 3‐6. 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. After installing the rubber feet, return the switch to its upright position.

Page 33: Connecting Stacking Cables
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.

Page 35: Configuring Switches In A Stack
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 3‐7, 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. ... -
Page 36: Recommended Procedures For New And Existing Stacks
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. -
Page 37: Adding A New Switch To An Existing Stack
Once the desired master unit has been selected, reset the system using the reset command. After the stack has been configured, you can use the show switch unit command to physically identify each unit. When you enter the command with a unit number, the MGR LED of the specified switch will blink for 10 seconds. The normal state of this LED is off for member units and steady green for the manager unit. Persistent data on all stack units can be cleared along with the current configuration using the clear config all as described in the SecureStack A2 Configuration Guide. Adding a New Switch to an Existing Stack Use the following procedure to install a new switch to an existing stack configuration. This procedure assumes that the new switch being added has a clean configuration from manufacturing and is running the same firmware image version as other switches in the stack. Ensure that power is off on the new switch being installed. Use one of the following methods to complete the stack cable connections: – If the running stack uses a daisy chain topology, make the stack cable connections from the bottom of the stack to the new switch (that is, STACK DOWN port from the bottom switch of the running stack to the STACK UP port on the new switch). – If the running stack uses a closed loop configuration, break the loop and make the stack cable connections to the new switch to close the loop. Apply power to the new switch. Using the clear config Command in a Stack When using the clear config command (as described in the SecureStack A2 Configuration Guide) to clear configuration parameters in a stack, it is important to remember the ... -

Transmit (TX) • Receive (RX) The transmit strand from a switch port connects to the receive port of a fiber‐optic Fast Ethernet device at the other end of the segment. The receive strand of the applicable LC port connects to the transmit port of the fiber‐optic Fast Ethernet device. Enterasys recommends labeling fiber‐optic cables to indicate receive and transmit ends. Many cables are pre‐labeled, providing matching labels or tapes at both ends of each strand of cable. To connect an LC cable connector to a fixed LC connector, refer to Figure proceed as follows: Caution: Do not touch the ends of the fiber-optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data transmissions. -
