Desk-Top Mounting

If the system chassis is going to be set on a desk or a shelf, you should install the rubber foot pads that are included in the accessory kit. To install the rubber feet, follow these steps:

Step 1 Place the switch upside down on a flat surface.

Step 2 Remove the adhesive foot pads from their backing, and place one in each corner on the bottom of the chassis. (See Figure 3-3.)

Step 3 Place the switch right-side up, and position it on the desk or shelf close to where the DC source and the system ground are located.

Figure 3-3 Installing the Rubber Feet

Installing the System Ground

The system (NEBS) ground provides additional grounding for EMI shielding requirements and is intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and grounding connections.

To connect the system ground, you need the following tools and materials:

Note The grounding lug and the grounding lug screws are supplied as part of the accessory kit. The grounding wire and the tools are not supplied as part of the accessory kit.

•Grounding lug—A two-hole standard 90-degree barrel lug. Supports up to 6 AWG wire.

•Grounding screws—Two M4 x 8 mm pan-head screws.

•Grounding wire—The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. We recommend that you use commercially available 6 AWG wire. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

•No. 1 Phillips screwdriver.

•Wire-stripping tool to remove the insulation from the grounding wire.

•Crimping tool to crimp the grounding wire to the grounding lug.

To attach the grounding lug and cable to the grounding pad, follow these steps:

Step 1 If you are using insulated wire, use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire. If you are using bare wire, go to Step 2.

Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug.

Step 3 Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground lug.

Step 4 Place the grounding wire lug against the grounding pad, making sure that there is solid metal-to-metal contact.

Step 5 Secure the grounding lug to the chassis with two M4 screws. (See Figure 3-4.) Ensure that the grounding lug and the grounding wire do not interfere with other switch hardware or rack equipment.

Step 6 Prepare the other end of the grounding wire, and connect it to an appropriate grounding point in your site to ensure adequate earth ground for the switch.

Figure 3-4 Installing the System Ground

Connecting Source Power to the Chassis

This section provides instructions on connecting source power to the chassis. Two procedures are provided:

•Connecting Source DC to the DC-Input Power Supply

•Connecting Source AC to the AC-Input Power Supply

Note The ME6524 switches support mixing AC-input and DC-input power supplies in the same chassis.

Connecting Source DC to the DC-Input Power Supply

To connect source DC to the DC-input power supply, follow these steps:

Step 1 Ensure that the system (earth) ground chassis connection has been made.

Step 2 Verify that power is off to the DC circuit that feeds the power supply that you are connecting.

As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.

Step 3 Verify that the power switch is in the off (0) position on the power supply that you are connecting.

Step 4 Verify that the power supply is fully seated in the chassis power supply bay and that the two captive installation screws on the power supply are tight.

Step 5 Remove the plastic cover from the terminal block.

Step 6 Attach the appropriate lugs to the source DC cables. The maximum width of a lug is 0.300 inch (7.6 mm).

Either insulated crimp-on spade lugs or insulated crimp-on ring connectors can be used on the source DC cables. They should be sized according to local and national installation requirements and electrical codes.

Note The source DC cables should be sized according to local and national installation requirements and electrical codes. Use only copper wire.

Step 7 Connect the DC-input cables to the power supply terminal block in this order:

1. Ground cable to the ground connector on the terminal block

2. Negative (-) source DC cable to the negative (-) connector on the terminal block

3. Positive (+) source DC cable to the positive (+) connector on the terminal block

Step 8 After ensuring that all of the source DC cable connections are secure, reinstall the plastic terminal block cover.

Caution To prevent a short circuit or shock hazard after wiring the DC-input power supply, you must reinstall the terminal block cover.
Caution In a system with dual power supplies, connect each power supply to a separate power source. In case of a power source failure to one supply, the second power source should still be available.

Step 9 Remove any safety flag and lockout devices or any tape from the circuit breaker switch handle, and restore power by moving the circuit breaker switch handle to the on (|) position.

Connecting Source AC to the AC-Input Power Supply

To connect source AC to the AC-input power supply, follow these steps:

Step 1 Verify that the power switch is in the off (0) position on the power supply that you are connecting.

Step 2 Verify that the power supply is fully seated in the chassis power supply bay and that the two captive installation screws on the power supply are tight.

Step 3 Plug the AC power cord appliance connector (C15 connector) into the AC-in receptacle on the power supply.

Step 4 Plug the other end of the AC power cord into the source AC outlet.

Connecting the Console Port

This section describes how to connect to the console port from a terminal or modem.

The console port allows you to perform the following functions:

•Configure the switch from the CLI.

•Monitor network statistics and errors.

•Configure SNMP agent parameters.

•Download software updates to the switch or distribute software images that reside in flash memory to attached devices.

The console port, located on the chassis front panel, is shown in Figure 3-5.

Figure 3-5 Connecting the Console Port

Note The accessory kit that shipped with your Cisco ME 6524 Ethernet switch contains a cable to connect a terminal or modem to the console port.

To connect a terminal to the console port using the cable and adapters provided, follow these steps:

Step 1 Connect one end of the console port cable to the CONSOLE port using the RJ-45-to-RJ-45 cable.

Step 2 Position the cable so that there are no sharp bends in the cable.

Step 3 Connect the other end of the console port cable to the terminal or modem.

Step 4 Check the terminal documentation to determine the baud rate. The baud rate of the terminal must match the default baud rate (9600 baud) of the console port. Set up the terminal as follows:

•9600 baud

•8 data bits

•No parity

•2 stop bits

Installing the SFP Transceivers

These sections describe how to install the SFP transceivers. SFP transceivers are inserted into the downlink and uplink SFP sockets on the front of the Cisco ME 6524 Ethernet switch. These field-replaceable transceivers provide the downlink and the uplink optical interfaces.

You can use any combination of SFP transceivers. The only restriction is that each port must match the wavelength specifications on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications.

Use only Cisco SFP transceivers on the Cisco ME 6524 Ethernet switch. Each SFP transceiver has an internal serial EEPROM that is encoded with security information. This encoding allows Cisco to identify and validate that the SFP transceiver meets the requirements for the switch.

Figure 3-6 shows an optical SFP transceiver equipped with a bail-clasp latch.

Caution We strongly recommend that you do not install or remove the SFP transceiver with fiber-optic cables attached to it because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP transceiver. Disconnect all cables before removing or installing an SFP transceiver.

Removing and installing an SFP transceiver can shorten its useful life. Do not remove and insert SFP transceivers more often than is absolutely necessary.

Figure 3-6 Optical SFP Transceiver with a Bail-Clasp Latch

To insert an SFP transceiver into the SFP socket, follow these steps:

Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to attach an ESD grounding strap, see the "Preventing Electrostatic Discharge Damage" section on page 2-7 for instructions.)

Step 2 Remove the SFP transceiver from its protective packaging.

Step 3 Check the label on the SFP transceiver body to verify that you have the correct model for your network, and locate the send (Tx) and receive (Rx) markings that identify the top side of the SFP transceiver.

Note On some SFP transceivers, the Tx and Rx marking might be replaced by arrows that point from the SFP transceiver connector (transmit direction or Tx) to the connector (receive direction or Rx).

Step 4 Carefully insert the SFP transceiver halfway into the socket. (See Figure 3-7.) Remove the optical bore dust plugs, pivot the transceiver bail-clasp up, and continue sliding the transceiver into the socket until you feel the SFP transceiver module connector snap into place in the socket connector.

Step 5 Pivot the SFP transceiver bail-clasp fully down to lock the transceiver in place, and immediately reinstall the dust plugs.

Figure 3-7 Installing an SFP Transceiver into an SFP Transceiver Socket

Caution Do not remove the dust plugs from the SFP transceiver port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP transceiver ports and cables from contamination and ambient light.
Caution To comply with GR-1089 intrabuilding lightning surge immunitry requirements, you must use shielded, twisted-pair, Category 5 cabling with both ends of the shield grounded.

Note For optical SFP transceivers, before removing the dust plugs and making any optical connections, observe the following guidelines:

•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.

•Always inspect and clean the LC connector end-faces prior to making any connections. For more information, see the document at this URL:

http://www.cisco.com/en/US/tech/tk482/tk607/technologies_white_paper09186a0080254eba.
shtml

•Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

Step 6 Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.

Step 7 Inspect and clean the LC connector's fiber-optic end-faces.

Tip For complete information about inspecting and cleaning fiber-optic connections, see the document at this URL:

http://www.cisco.com/en/US/tech/tk482/tk607/technologies_white_paper09186a0080254eba.shtml

Step 8 Remove the dust plugs from the SFP transceiver optical bores.

Step 9 Immediately attach the network interface cable LC connector to the SFP transceiver.

Powering Up the Chassis

Turn on the power supply switches to power up the system. During the power-up sequence, the system performs a series of bootup diagnostic tests.

Additional system diagnostic tests are available. These tests allow you to perform a complete sanity check on the system prior to inserting the system into your network and to monitor the health of the system while the system is running.

Where to Go Next

If the default configuration is satisfactory, the switch does not need further configuration. However, you may use the CLI from the console to configure the switch as a member of a cluster or as an individual switch. See the Cisco ME 6500 Series Ethernet Switch Software Configuration Guide and the Cisco ME 6500 Series Ethernet Switch Cisco IOS Command Reference on Cisco.com for information on using the CLI with a Cisco ME 6524 Ethernet switch.
