Dimension GS-1116A/GS-1124A Gigabit Switch Chapter 2 Hardware Description and Installation This section discusses switch installations, hardware and functional overview. The switch is suited to an office environment where it can be rack mounted on standard EIA racks or placed as a standalone switch on a desktop. ) For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front, 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations. 2.
Dimension GS-1116A/GS-1124A Gigabit Switch 2.2 Rack-mounted Installation The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using the included rack-mounting kit. 1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws. Similarly, attach the other bracket. Figure 2-2 Attaching Mounting Brackets and Screws 2.
Dimension GS-1116A/GS-1124A Gigabit Switch 2.3 Rear Panel The ventilation fan and three-pronged power receptacle are located on the rear panel of the switch. Figure 2-4 Switch Rear Panel 2.3.1 Rear Panel Power Connection Connect one end of the supplied power cord to the power receptacle on the back of the switch and the other end to the 100-240 VAC, 50-60 Hz power source. Push the power switch to the ON position. 2.
Dimension GS-1116A/GS-1124A Gigabit Switch • 100Mbps or 1000Mbps in full-duplex mode depending on your Ethernet network. 2.4.2 Auto-sensing (Auto MDI/MDIX) Ports You can connect each RJ-45 auto-sensing port to a computer, hub or switch using either a straight through or a crossover Ethernet cable. 2.4.3 Mini GBIC Slots These are slots for Mini GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single unit that houses a transmitter and a receiver.
Dimension GS-1116A/GS-1124A Gigabit Switch Figure 2-7 Transceiver Installation Procedure Transceiver Removal Use the following steps to remove a mini GBIC transceiver (SFP module) from the GBIC port. 1. Remove the fiber-optic cables from the transceiver. 2. Unlock the transceiver’s latch (latch styles vary). 3. Pull the transceiver out of the slot. 4. Put the transceiver’s dust cover on the transceiver.
Dimension GS-1116A/GS-1124A Gigabit Switch Figure 2-8 Transceiver Removal Example ) Keep the dust cover on a fiber optic module until you connect it. Use the appropriate Ethernet or fiber-optic cables to connect the module to an Ethernet switch. With a fiber-optic module, remove the dust covers from the connectors. You may need to clean the fiberoptic cable’s connectors with a cotton swab dipped in alcohol. 2.4.
