Figyelmeztetés	Figyelmeztetés a felhasználói kézikönyv számára: Ez a berendezés "A" osztályú termék, felhasználására és üzembe helyezésére a magyar EMC "A" osztályú követelményeknek (MSZ EN 55022) megfeleloen kerülhet sor, illetve ezen "A" osztályú berendezések csak megfelelo kereskedelmi forrásból származhatnak, amelyek biztosítják a megfelelo speciális üzembe helyezési körülményeket és biztonságos üzemelési távolságok alkalmazását.

Note In some installations, you also need the screw template and three number-8 Phillips pan-head screws. These are included in the accessory kit with the switch.

Installation Guidelines

Connect all cables to the switch before assembling the switch and cable guard. The switch and cable guard assembly is then mounted on a wall or on or under a desk.

Note Cables cannot be connected to the switch after it is attached to the cable guard. For information about connecting devices to the switch, refer to the hardware installation guide.

Before you begin, decide how to mount the cable guard and switch by reviewing these sections:

Installing the Switch (Front Panel Facing Down)

Step 1

Locate the screw template (included in the switch accessory kit). The template is used to align the mounting screw holes and is also used as a guide to make sure that the screws are installed in the wall with proper clearance.

Step 2

Position the screw template so that the two side-by-side slots face toward the floor, as shown in Figure 1. For the best support of the switch and cable guard, make sure the switch and cable guard are attached securely to a wall stud or to a firmly attached plywood mounting backboard.

1	Wall
2	Screws
3	Screw template

Step 5

Use a 0.144-in. (3.7 mm) or a #27 drill bit to drill three 1/2-in. (12.7 mm) holes in the wall, using the screw template slots for alignment.

Step 6

Insert the three number-8 Phillips pan-head screws in the slots on the screw template, and tighten until they touch the top of the screw template.

Step 8

Attach the cables to the switch, as shown in Figure 2. For information about devices that can be connected to the switch, refer to the hardware installation guide.

Step 9

Slide the switch into the cable guard, as shown in Figure 3, ensuring that all connected cables are routed through the slots in the front of the cable guard. Three hooks on the top of the cable guard secure the bottom of the switch against the cable guard.

Step 10

Guide the connected cables through the slots in the front of the cable guard. The completed switch and cable guard assembly is shown in Figure 4.

Step 11

Use two of the included number-8 Phillips truss-head screws to attach the front of the cable guard to the switch, as shown in Figure 5.

Step 12

(Optional) Use the third number-8 Phillips truss-head supplied screw to attach the bottom of the switch to the cable guard, as shown in Figure 6. This optional screw helps prevent the switch from being easily removed from the cable guard.

Slide the assembled cable guard and switch onto the three mounting screws, as shown in Figure 7.

Step 13

(Optional) Use the three of the number 8-18 Phillips pan-head screws supplied screws to further secure the cable guard and switch on the wall, as shown in Figure 8.

Note You can use the three number-8 Phillips pan-head screws that are included in the switch accessory kit for this step.

Installing the Switch (Front Panel Facing Up)

•

Do not use the screw template, and do not install the wall mount screws as described in Step 1 through Step 7.

•

Install the three number 8 Phillips pan-head screws to mount the switch and cable guard assembly, as described in Step 13. This step is not optional when the switch is installed with the front panel facing up.

Installing the Switch On or Under a Desk

You can install the cable guard and switch on or under a desk. Follow the same steps in the "Installing the Switch (Front Panel Facing Down)" section, but use the screw template to install the mounting screws on or under the desk instead of on a wall.

Installing the Cable Guard with a Previously-Installed Switch

•

If you are mounting the cable guard and switch assembly with the front panel facing down, use the same three mounting screws that are already installed in the wall and go to Step 9.

Note

You might need to turn the wall-mounted screws 1/4 turn counterclockwise before mounting the switch and cable guard assembly on the wall (the cable guard is made of thicker material than the switch chassis.)

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

•

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

•

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

•

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

•

Priority level 1 (P1)—An existing network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website.
