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. 5.
Installing the Switch on a Flat Surface Caution: 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. Do not connect the switch to the AC power source until instructed to do so later in the installation process. Precaución: Para asegurar una buena ventilación y evitar que el sistema se sobrecaliente, deje un espacio mínimo de 5.1 cm (2 pulgadas) con respecto a los lados y a la parte posterior del aparato.
Rack Mounting the Switch Rack Mounting the Switch To install the switch in a 19‐inch rack, you need: • Two rackmount brackets and mounting screws (rackmount kit) shipped with the switch. • Four user‐supplied screws to attach the switch to a standard 19‐inch rack. Guidelines for Rackmount Installation The installation site must be within reach of the network cabling and meet the requirements listed below: • Appropriate grounded power receptacles must be located within 152 cm (5 ft) of the location.
Rack Mounting the Switch Attaching Brackets and Installing in Rack Proceed as follows to install the switch into a 19‐inch rack: 1. Attach the rackmount brackets to the switch, as shown in Figure 3‐7, using the eight M3x6 mm flathead screws shipped with the switch. Figure 3-7 Attaching the Rackmount Brackets 1 Rackmount brackets 2. With the mounting brackets attached, position the switch between the vertical frame members of the 19‐inch rack as shown in Figure 3‐8.
Connecting High-Speed Stacking Cables Connecting High-Speed Stacking Cables The stack of switches can be connected in a ring or daisy chain topology. In a ring topology all the switches are connected. The only difference in the cable connections in a daisy chain topology is that one cable is not installed. Up to seven or eight switches can be stacked together and connected by high‐speed stacking cables. You can add switches and reach up to a maximum of 384 Ethernet ports per stack.

Configuring Switches in a Stack 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 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.
Configuring Switches in a Stack 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.
Connecting AC and RPS-SYS Power 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. 1. Ensure that power is off on the new switch being installed. 2. Use one of the following methods to complete the stack cable connections: 3.

Connecting to the Network Connecting Fiber-Optic Cables to MT-RJ Ports Warning: Fiber-optic Mini-GBICs use Class 1 lasers. Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter. Advertencia: Los Mini-GBICS de fibra optica usan lasers de clase 1. No se debe usar instrumentos opticos para ver la potencia laser.
Connecting to the Network . 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. If the ends of the fiber-optic strands become contaminated, use a canned duster to blow the surfaces clean. A fiber-port cleaning swab saturated with optical-grade isopropyl alcohol may also be used to clean the ends.
Connecting to the Network 4. Verify that a link exists by checking that the port Link/Activity LED is on (blinking green or solid green). If the Link/Activity LED is off, perform the following steps until it is on: a. Verify that the device at the other end of the segment is ON and connected to the segment. b. If there are separate fiber‐optic connections on the other device, check the crossover of the cables. Swap the cable connections if necessary. c.
Connecting to the Network The transmit strand from a switch port connects to the receive port of a fiber‐optic Gigabit 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 Gigabit 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.
