[. . . ] Keep the device far from radio transmitting stations, radar stations, and high-frequency devices. Use electromagnetic shielding when necessary, for example, use shielded interface cables. Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes. 2. 2. 4 Laser Safety The S5600 Series Ethernet Switches are class-1 laser devices. If the optical boards on your switch are operating, do not stare into the optical ports because the laser light emitted by the optical fiber can hurt your retina. Caution: Staring into the laser beam produced by the fiber can hurt your eyes. 2. 3 Installation Tools Flat-blade screwdriver Phillips screwdriver ESD-preventive wrist strap Caution: The installation tools are not provided with the S5600 series. 2-3 Installation Manual H3C S5600 Series Ethernet Switches Chapter 3 Installing the Switch Chapter 3 Installing the Switch Caution: When you ask your sales agent to maintain the switch, you must ensure that the dismantlement-preventive seal on a mounting screw of the switch chassis is intact. If you want to open the chassis, you should contact the agent for permission. Otherwise, you will bear any consequence resulted from your actions without permission. 3. 1 Rack-Mounting the Switch You can install a switch into a 19-inch standard cabinet in one of the following three ways: Use front mounting ears and a tray Use front mounting ears and rear mounting ears Use front mounting ears and guide rails Note: The front mounting ears and rear mounting ears are delivered with the device, no guide rails are delivered with the device. The front mounting ears only secure the switch rather than bear its weight. Guide rails purchased from H3C apply only to standard cabinets 1, 000 mm (39. 4 in) deep. Use other supports to substitute for guide rails in the case of other cabinet depths. 3. 1. 1 Introduction to mounting ear Figure 3-1 shows the appearance of a front mounting ear. 3-1 Installation Manual H3C S5600 Series Ethernet Switches (1) (2) Chapter 3 Installing the Switch L1 L2 (1): Screw hole used to fix the mounting ear to the cabinet (Use one M6 screw) (2): Screw hole used to fix the switch to the mounting ear Figure 3-1 Appearance of a front mounting ear Figure 3-2 shows the appearance of a rear mounting ear.

You should select a proper position according to the actual requirements. The rear mounting ears tightly contacted with the load-bearing screws can support the switch. 4) Select a position to install the switch and fix the rear mounting ears to the rear brackets with screws and captive nuts, as shown in Figure 3-7. Rear square-holed rack Figure 3-7 Fix rear mounting ears 5) Hold the bottom of the switch with one hand and the front part of the switch with the other hand, and pull the switch into the cabinet gently, as shown in Figure 3-8. 3-5 Installation Manual H3C S5600 Series Ethernet Switches Chapter 3 Installing the Switch Rear mounting ear Front square-holed bracket Screw 2 Rear square-holed bracket Front mounting ear Rear panel Screw 1: Used to bear the weight Screw 2: Used to fix rear mounting ears to rear brackets Figure 3-8 Fix front and rear mounting ears After the switch is pushed into the cabinet, ensure that the upper edge of rear mounting ears is tightly contacted with the load-bearing screw, as shown in Figure 3-9.

Ensure that the bottom side of the guide rails and the switch are in close contact. Front panel Figure 3-13 Install front mounting ears and guide rails 5) Fix the other end of front mounting ears to the front brackets of the cabinet with M6 screws and captive nuts and ensure that the front mounting ears and guide rails have fixed the switch in the cabinet securely, as shown in Figure 3-14. 3-8 Installation Manual H3C S5600 Series Ethernet Switches Chapter 3 Installing the Switch Rear panel Guide rail Figure 3-14 Effect diagram of front mounting ear and guide rail installation Note: Ensure a clearance of 1U (44. 45 mm, namely, 1. 75 inches) between devices for the purpose of heat dissipation. 3. 2 Mounting the Switch on a Tabletop/Workbench When placing the switch on a tabletop or workbench, you simply need to: Make sure that the tabletop or workbench is clean, flat, and sturdy. Allow 10 cm (3. 9 in. ) of clearance around the sides of the chassis. Do not place heavy objects on the switch. 3-9 Installation Manual H3C S5600 Series Ethernet Switches Chapter 3 Installing the Switch 3. 3 Installing/Removing the Power Module Caution: To avoid bodily injury, do not touch any bare conducting wire, screw, and the part which is labeled danger voltage. 3. 3. 1 Installing the Power Module The power module of the S5600 series is swappable. Follow those steps to install the power module: Step 1: Wear an ESD wrist strip, and make sure it is well grounded. [. . . ] You should correctly locate the problem, whether it is caused because the ground wire of the arrester is not well grounded or because the live and zero wires are connected in reverse direction. You may check that in the following way. When the red LED is on, use a multimeter to examine polarity at the power socket of the arrester. If it is same to that of the power socket in the equipment room, it means that arrester is not well grounded. [. . . ]
