Ether-GSH24T 24-Port Gigabit Ethernet Switch User’s Manual
FCC Warning This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this user’s guide, may cause harmful interference to radio communications.
UL Warning a) Elevated Operating Ambient Temperature-If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature (Tmra).

About This Guide This user’s guide tells you how to install your 24-Port 1000BASE-T Gigabit Ethernet Switch, how to connect it to your Gigabit Ethernet network. Terms For simplicity, this documentation uses the terms “Switch” (first letter upper case) to refer to the 24-Port 1000BASE-T Gigabit Ethernet Switch, and “switch” (first letter lower case) to refer to all Ethernet switches, including the 24-Port 1000BASE-T Gigabit Ethernet Switch. Overview of this User’s Guide Introduction.
Introduction This section describes the features of the 24-Port 1000BASE-T Gigabit Ethernet Switch, as well as giving some background information about Gigabit Ethernet and switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.
Gigabit Ethernet supports video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time. Switching Technology Another key development pushing the limits of Ethernet technology is in the field of switching technology.
Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical. Today’s switches are an ideal solution to most kinds of local area network congestion problems.
Unpacking and Setup This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: ♦ One 24-Port 1000BASE-T Gigabit Ethernet Switch ♦ Accessory pack: 2 mounting brackets and screws ♦ Four rubber feet with adhesive backing ♦ One AC power cord ♦ This User’s Guide If any item is found missing or damaged, please contact your local reseller for replacement.
♦ Visually inspect the power cord and see that it is secured fully to the AC power connector. ♦ Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Do not place heavy objects on the Switch. Desktop Installation When installing the Switch on a desktop or shelf, the rubber feet included with the device must be first attached. Attach these cushioning feet on the bottom at each corner of the device.
Rack Installation The Switch can be mounted in an EIA standard size, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the switch’s front panel (one on each side) and secure them with the screws provided. Attaching the mounting brackets to the Switch Then, use the screws provided with the equipment rack to mount the Switch in the rack.
Identifying External Components This chapter describes the front panel, rear panel and LED indicators of the Switch Front Panel The front panel of the Switch consists of 24 1000BASE-T Gigabit Ethernet ports and LED indicators. Front panel view of the Switch Sixteen Gigabit Ethernet ports of 10/100/1000Mbps Auto-Negotiation interface. Comprehensive LED indicators that display the conditions of the Switch and status of the network. A description of these LED indicators follows (see LED Indicators).
Rear Panel The rear panel of the Switch consists of an AC power connector. The following shows the rear panel of the Switch. Rear panel view of the Switch ♦ AC Power Connector This is a three-pronged connector that supports the power cord. Plug in the female connector of the provided power cord into this connector, and the male into a power outlet. Supported input voltages range from 100 - 240 VAC at 50/60 Hz.
LED Indicators The LED indicators of the Switch include Power, Link/Act, 1000Mbps and 100Mbps. The following shows the LED indicators for the Switch along with an explanation of each indicator. The Switch LED indicators Per unit: Power This indicator lights green when the Switch is receiving power, otherwise, it is off. Per port: Link/ACT.
