Installation

Before installing the management switch, verify that the package contains the following items:

• The Switch
• Self-adhesive rubber pads for desktop installation
• Rack mount kit for rack installation
• User guide
• AC power cord

If any items are missing or damaging, contact your dealer immediately.

The Switch can be mounted on any appropriate level surface that can safely support the weight of the hubs and their attached cables. There must be adequate space around the switch for ventilation and access cable connectors.

To install the switch on a flat surface, tabletop, shelf, etc. follow these steps:

1. Set the switch on the flat surface and check for proper ventilation

Allow at least 2 inches (5.1 cm) on each side for proper ventilation and 5 inches (12.7 cm) at the back for power cord clearance.

2. Attach rubber feet on each marked location on the bottom of the chassis

The rubber feet are optional but recommanded to keep the unit from slipping.

3. Attach all device to the port

The Switch can be installed in most standard 19-inch racks.

To install the Switch in a rack, follow these steps:

• Determine how far you want the Switch to protrude in front of the rack.You can install the Switch slush to the rack or extended from the rack.

• Using the supplied screws to attach a mounting bracket to each side of the Switch.

• Position the Switch in the rack and align the holes in the mounting bracket with the holes in the rack.

• Insert two screws, appropriate for your 19-inch rack, into each of the mounting brackets and tighten.

This section describes how to connect devices to the switch ports and how to connect a console terminal to the hub Console port. You can connect the switch to any equipment that conforms to the IEEE 802.3 standard.

• Connecting the 10BASE-T/100BASE-TX Ports

The Switch has 24 10BASE-T/100BASE-TX ports, which are configured with RJ-45 connectors. The ports connect via straight-through cables to the network interface card (NIC) in a node or server. (See Figure 2-2)

When connecting to another hub or switch (See the Cascading to another hub or switch section), you just need to use straight-through Category 5 twist-pair cable. The Switch has an Uplink button that controls the polarity of port 1. Means that you can connect port 1 of the Switch to another switch or hub when this button is in depressed position. When this button is in raised position, it works like another ports.

• Connecting the Console Port

The Switch provides an RS-232 port that enables a connection to a PC or terminal for monitoring and configuring the switch. This port is a male DB-9 connector, implemented as a data terminal equipment (DTE) connection.

To use the Console port, you need the following equipment:

• A terminal or TTY-compatible terminal, or a PC or portable computer with a serial port and the ability to emulate a terminal.

The terminal should have the following settings:

• 9600 baud
• No parity
• 8 bits
• 1 stop bit
• flow control set to none
• Window Terminal Emulation option set to NO

• A crossover RS-232 cable with a female DB-9 connector for the console port on the switch

To connect a terminal to the console port, follow these steps:

1. Set the terminal protocol as described above.
2. Connect the female connector of the RS-232 cable directly to the Console port on the hub, and tighten the captive retain screws. (See Figure 2-3)
3. Connecting the other end of the cable to a terminal or the serial connector of a PC running communication software.

• Cascading to another hub or switch

You can expand the Switch by cascading to another hub or switch. One up-link push button on the front panel allows users to connect to either a hub or a desktop, using straight-through Category 5 twist-pair cable. When the 1^st port is connected to a desktop, the push bottom is adjusted to the Normal position (MDI-X). If the 1^st port is connected to another hub or switch, the push button has to be on the Uplink (MDI).

When you add connectivity for 100 Base-Fx transmission media, please insert the optional MII fiber-optic module in the MII Module Slot on the rear panel
