If any item is missing or damaged, contact your Cisco representative or reseller for support. You need to supply a number-2 Phillips screwdriver to rack-mount the switch. Before you install the switch in a rack, on a wall, or on a table or shelf, you should power on the switch and verify that the switch passes POST. Set the RPS to active mode during normal operation. To p ower on the switch, connect one end of the AC power cord to the AC power connector on the switch, and connect the other end of the power cord to an AC power outlet.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. The other LEDs turn off and then reflect the switch operating status. POST failures are usually fatal. After a successful POST, disconnect the power cord from the switch. This section applies to all switches except the Catalyst 8-port switches. This section describes these installation procedures:.
To install the switch in a inch or inch rack inch racks require optional mounting hardware , follow the instructions described in these sections:. An optional bracket kit that is not included with the switch is required to install the switch in a inch rack.
If you plan to install the switch in a rack, you must first remove screws in the switch chassis so that you can attach the mounting brackets. Figure shows how to remove the chassis screws in a Catalyst switch. Figure Removing Screws from the Catalyst Switch. The bracket orientation and the brackets that you use depend on whether you are attaching the brackets for a inch or a inch rack.
Figure to Figure show how to attach each type of bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side. After the brackets are attached to the switch, use the four supplied number Phillips machine screws to securely attach the brackets to the rack, as shown in Figure Figure Mounting the Catalyst Switch in a Rack.
After the switc h is mounted in the rack, do these tasks to complete the installation:. We recommend that you attach the cable guide to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack.

Figure shows how to attach a inch bracket to one side of the switch. Figure Attaching the inch Brackets for Wall-Mounting.
If your switch has an RPS connector and you are not using an RPS with your switch, use the two Phillips pan-head screws to attach the RPS connector cover to the back of the switch, as shown in Figure For the best support of the switch and cables, make sure the switch is attached securely to wall studs or to a firmly attached plywood mounting backboard.
Mount the switch with the front panel facing up, as shown in Figure Warning To comply with safety regulations, mount the switches on a wall with the front panel facing up. Figure Mounting the Switch on a Wall. After the switch is mounted on the wall, do these tasks to complete the installation:.
Step 1 Locate the adhesive strip with the rubber feet in the mounting-kit envelope. Attach the four rubber feet to the recessed areas on the bottom of the unit. Step 2 Place the switch on the table or shelf near an AC power source. After the switch is mounted on the table, do these tasks to complete the installation:. Note When the connectors are not being used, replace the dust covers on them for protection.
If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage. To order a cable guard, contact your Cisco representative using these part numbers:.
Depending on the Catalyst switch model, the switch can have an RJ console port, a fan exhaust, an RPS connector, and an AC power connector see Figure for an example of a Catalyst rear panel. Figure Catalyst Switch Rear Panel. RJ console port 4. RPS connector 5. Fan exhaust 6. AC power connector 7. The Catalyst 8-port switches have the console port on the front panel rather than on the rear panel. The Catalyst 8-port switches do not have a fan.
The internal power supply is an autoranging unit that supports input voltages between and VAC. Depending on the switch model, you can connect the switch to either of these Ci sco redundant power systems RPS to provide backup power if the switch power supply fails:.
The Cisco RPS is a redundant power system that supports six network switches and provides power to one or two failed switches at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic. The total maximum output power depends on the installed power-supply modules. All supported, connected switches can simultaneously communicate with the RPS You can configure these RPS features through the switch software:.

Product Overview The Catalyst switch—also referred to as the switch —is an Ethernet switch to which you can connect devices such as workstations, Cisco Wireless Access Points, Cisco IP Phones, and other network devices including servers, routers, and other switches. Each of the PoE ports on the Catalyst switches deliver up to On a per-port basis, you can control whether or not a Catalyst PoE port automatically provides power when an IP phone or an access point is connected.
The powered device might switch to the AC power source as its primary power source upon being connected to it. In that case, the PoE port becomes the backup power source for the powered device. Green System is operating normally.
Amber System is receiving power but is not functioning properly. Green RPS is connected and ready to provide back-up power, if required. Blinking green RPS is connected but is unavailable because it is providing power to another device redundancy has been allocated to a neighboring device. Amber The RPS is in standby mode or in a fault condition.
Blinking amber The internal power supply in a switch has failed, and the RPS is providing power to the switch redundancy has been allocated to this device. This is the default mode. Link fault. Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check CRC errors, and alignment and jabber errors are monitored for a link-fault indication.
After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the switch for possible loops. PoE mode is not selected. If the powered device is receiving power from an AC power source, the PoE port LED is off even if the powered device is connected to the switch port. PoE is on. The port LED is green only when the switch port is providing power. PoE is denied because providing power to the powered device will exceed the W switch power capacity.
Error frames can affect connectivity, and errors such as excessive collisions, CRC errors, and alignment and jabber errors are monitored for a link-fault indication. After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the network topology for possible loops.
