Install the heaviest device in the bottom of the rack cabinet.

Do not extend more than one device out of the rack cabinet at the same time.

Remove the rack doors and side panels to provide easier access during installation.

Connect the controller to a properly grounded outlet.

Do not overload the power outlet when you install multiple devices in the rack cabinet.

Install the controller in a rack that meets the following requirement:

Minimum depth of 70 mm (2.76 in.) between the front mounting flange and inside of the front door.


Caution Use safe practices when lifting.


Caution Do not place any object on top of rack-mounted devices.

The following illustration shows the items that you need to install the controller in the rack cabinet. If any items are missing or damaged, contact your place of purchase.


Note Some items come with the controller, not in the rack installation kit.


Note Use cage bars with square-holed racks, clip nuts with round-holed racks, and your own screws or the screws provided in this kit with threaded-hole racks.

Note If the slide rails in your rack installation kit came with shipping thumbscrews, remove them before you begin the following installation procedure.

Step 1 Select an available 1 U space in your rack to install your controller. If you have either a round-holed or square-holed rack, install cage bars or clip nuts in the middle and the bottom (optional for the upper) holes of the lower U on each side of the front of the rack. Then, install cage bars or clip nuts in the upper and the bottom holes of the lower U on each side of the rear of the rack.

Step 2 Use a screwdriver to install the cage bars or the clip nuts on the inside of the mounting rail, as required for your rack, into the selected holes.

Step 3 The rail depth can be adjusted from 17 in (432 mm) to 31.25 in (794 mm). To adjust the depth, you can loosen the nuts on the posts and slide the bracket until the distance between the front and rear slide rail flanges matches the distance between the front and rear EIA rails of the rack cabinet. If you need further adjustment, remove the nuts, move the bracket to the appropriate set of posts (A, B, C, and D) to obtain the appropriate slide rail depth, then reinstall and tighten the nuts.

Step 4 To remove the support bracket, remove the screw (1) and remove the bracket (2) from the rear of the slide rail.

Step 5 To remove the mounting brackets, remove the screws (1) and (3). Slide out the brackets (2) and (4) from the rear of the slide rail.

Step 6 Attach the front of the slide rail and EIA latch to the front of the rack cabinet by installing a screw in the bottom hole of the lower U; then, install another screw in the middle hole of the lower U to attach the front of the slide rail to the front of the rack cabinet.


Note When you fasten the slides to the rack, ensure the screws are engaged but the flange can move slightly. You will use a screwdriver to fully tighten them in Step 9.

Note Use 12-24 screws (not hex head M6 screws) on the front mounting bracket if you are installing this system into a rack with round or square holes (i.e., not threaded holes).

Step 7 Use two screws to attach the rear of the slide rail to the rear of the rack cabinet in the upper and the bottom holes of the lower U.

Repeat Step 3 through Step 7 to install the other slide rail into the rack.

Step 8 Pull the slide rails forward (1) until they click, two times, into place. Carefully lift the controller and tilt it into position over the slide rails so that the rear nail heads (2) on the controller line up with the rear slots (3) on the slide rails. Slide the controller down until the rear nail heads slip into the two rear slots, and then slowly lower the front of the controller (4) until the other nail heads slip into the other slots on the slide rails. Make sure that the front latch (5) slides over the nail heads.

Step 9 Lift the locking levers (1) on the slide rails and push the controller (2) all the way into the rack until it clicks into place.

Slide the system in and out twice to make sure the system slides correctly. Push the system inwards to the rack as close as possible but able to access the screws with a screwdriver. Then tighten the screws with a screwdriver.

Step 10 Slide the controller into the rack until it snaps into place. To slide the controller out of the rack, press on the release latches (1).


Note When you move the rack cabinet, or if you install the rack cabinet in a vibration-prone area, insert the optional M6 screws (2) in the front of the controller.

Cisco Flex 7500 Series Wireless Controller Power Features

Specific steps to power-on the Cisco Flex 7500 Series Wireless Controller are provided in Powering On the Controller.

When the controller is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor (the Integrated Management Module) is shut down; however, the controller can respond to requests to the service processor, such as a remote request to turn on the controller. The power-on LED flashes to indicate that the controller is connected to power but is not turned on.

Turning on the Cisco Flex 7500 Series Wireless Controller

Approximately 5 seconds after the controller is connected to power, one or more fans might start running to provide cooling while the system is connected to power, and the power-on button LED will blink quickly. Approximately 20 to 40 seconds after the controller is connected to power, the power-control button becomes active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while the controller is connected to power. You can turn on the controller by pressing the power-control button.

If a power failure occurs while the controller is turned on, the system will restart automatically when power is restored.

Turning off the Cisco Flex 7500 Series Wireless Controller

When you turn off the controller and leave it connected to power, it can respond to requests to the service processor, such as a remote request to turn on the controller. While the controller remains connected to power, one or more fans might continue to run. To remove all power from the controller, you must disconnect it from the power source.


Caution The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

The integrated management module (IMM) can turn off the controller as an automatic response to a critical system failure.

Grounding the Chassis


Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.

Preventing ESD Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled and can result in complete or intermittent failures.

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect the strap to any unpainted surface on the chassis


Caution Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Replacing a Failed Hot-Swap Hard Disk Drive

To replace a 2.5-inch hot-swap SAS hard disk drive, complete the following steps.

You can order replacement hard disk drives from Cisco. The replacement part PID is AIR-SRVR-146GB-HD=.


Step 1 Read the safety information in General Warnings, Regulatory and Safety.

Step 2 Touch the static-protective package that contains the drive to any unpainted metal surface on the controller; then, remove the drive from the package and place it on a static-protective surface.

Step 3 Ensure that the drive you are replacing has failed before pulling it out of the drive slot. Press on the tray handle to unlock the drive. Pull on the tray handle to remove the drive.

Step 4 Install the hard disk drive in the drive bay:

a. Make sure that the tray handle is in the open (unlocked) position.

b. Align the drive assembly with the guide rails in the bay.

c. Gently push the drive assembly into the bay until the drive stops.

d. Rotate the tray handle to the closed (locked) position.

e. Check the hard disk drive status LED to verify that the hard disk drive is operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.


Replacing a Hot-Swap AC Power Supply

The following section describes the type of ac power supply that the server supports and other information that you must consider when you replace a failed power supply:

The Cisco Flex 7500 Series Wireless Controller comes with two 675-watt hot-swap 12-volt output power supplies that connect to power supply bays 1 and 2. The input voltage is 110 V ac or 220 V ac auto-sensing.

Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power supply immediately.

You can order replacement power supplies from Cisco. The replacement part PID is AIR-SRVR-PWR=.

These power supplies are designed for parallel operation. In the event of a power-supply failure, the redundant power supply continues to power the system.


Caution The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.


Caution Never remove the cover on a power supply or any part that has the following label attached. Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

To install a hot-swap power supply, complete the following steps.


Step 1 Read the safety information in General Warnings, Regulatory and Safety.

Step 2 Touch the static-protective package that contains the hot-swap power supply to any unpainted metal surface on the controller; then, remove the power supply from the package and place it on a static-protective surface.

Step 3 Remove the failed power supply first. Grasp the handle on the rear of the power supply and slide the power supply out from the chassis.

Step 4 Grasp the handle on the rear of the power supply and slide the power supply forward into the power-supply bay until it clicks. Make sure that the power supply connects firmly into the power-supply connector.

Step 5 Route the power cord through the handle so that it does not accidentally become unplugged.

Step 6 Connect the power cord for the new power supply to the power-cord connector on the power supply.

Step 7 Connect the other end of the power cord to a properly grounded electrical outlet.

Step 8 Make sure that the ac power LED and the dc power LED on the ac power supply are lit, indicating that the power supply is operating correctly. The two green LEDs are to the right of the power-cord connector.


Connecting the Cables

Figure 1-10 shows the locations of the input and output connectors on the front of the server.

Figure 1-11 Rear of Cisco Flex 7500 Series Wireless Controller

Connecting and Using the CLI Console

For initial system configuration, use the command-line interface (CLI) console. The CLI console connects to the controller back-panel DB9 console port. Figure 1-6 shows the console port on the back panel of the controller. Back panel components are described in Rear Panel Components.

Use these terminal emulator settings for the CLI console session:

9600 baud

8 data bits

no flow control

1 stop bit

no parity

Powering On the Controller

When you apply AC power to a controller, the bootup script initializes the operating system and its stored configurations. You are prompted to enter a user ID and password and enter key configuration details.

Follow these steps to power up the controller.


Step 1 Plug an AC power cord into the back of the two power supplies (Figure 1-6). If only one power supply is connected to a power source, the system will still function correctly but the monitoring components of the controller will detect the absence of the second power supply and will raise an alarm. Connect the other end of the power cord to a properly grounded 100 to 240 VAC 50/60 Hz electrical outlet.

The end of the power cord that plugs into the controller conforms with the IEC 320 standard.

Step 2 Use the front-panel Power On/Standby button, located in the operator information panel, to turn the controller on (Figure 1-3).

Step 3 At the login prompt, enter the controller operating user ID and password. The default user ID is root and the default password is password.

The user ID and password are case sensitive.

You are now logged into the controller operating system.

Continue to the "Running the Bootup Script and Power-On Self Test" section.


Running the Bootup Script and Power-On Self Test

When you plug the controller into an AC power source, the bootup script initializes the system, verifies the hardware configuration, loads its microcode into memory, verifies its operating system software load, and initializes itself with its stored configurations. Before performing this test, you should connect your terminal emulator application to the controller's CLI console as described in the "Connecting and Using the CLI Console" section. Follow these steps to run the bootup script and conduct the power-on self test (POST).


Step 1 Plug an AC power cord into the back of the controller and connect the other end to a grounded 100 to 240 VAC, 50/60 Hz electrical outlet. Be sure to connect both power supplies to a power source.

Step 2 Turn on the power supply.

Step 3 Observe the bootup on the CLI screen.

The bootup script displays operating system software initialization (code download and POST verification) and basic configuration as shown in the following sample bootup display:

Step 6 If the controller passes the power-on self test, the bootup script runs the Startup Wizard, which prompts you for basic configuration input.


Using the Startup Wizard

Before you can use the startup wizard, you must obtain the information discussed in the "Required Tools and Information" section.


Note The available options appear in brackets after each configuration parameter. The default value appears in all uppercase letters.

Note Press the hyphen key if you need to return to the previous command line.

To configure the controller for basic operation using the Startup Wizard, follow these steps:


Step 1 When prompted to terminate the AutoInstall process, enter yes. If you do not enter yes, the AutoInstall process begins after 30 seconds.

Welcome to the Cisco Wizard Configuration Tool
Use the '-' character to backup
 
   
Would you like to terminate autoinstall? [yes]:
AUTO-INSTALL: starting now...
rc = 0
 
   

Note The AutoInstall feature downloads a configuration file from a TFTP server and then loads the configuration onto the controller automatically.

Step 2 Enter the system name, which is the name you want to assign to the controller. You can enter up to 31 ASCII characters.

System Name [Cisco_d9:3d:66] (31 characters max):
AUTO-INSTALL: no interfaces registered.
 
   
AUTO-INSTALL: process terminated -- no configuration loaded
 
   

Step 3 Enter the administrative username and password to be assigned to this controller. You can enter up to 24 ASCII characters for each.

Enter Administrative User Name (24 characters max): admin
Enter Administrative Password (3 to 24 characters): ******
Re-enter Administrative Password                 : ******
 
   

Step 4 If you want the controller's service-port interface to obtain an IP address from a DHCP server, enter DHCP. If you do not want to use the service port or if you want to assign a static IP address to the service-port interface, enter static.

Service Interface IP Address Configuration [static][DHCP]: static
 
   

Note The service-port interface controls communications through the service port. Its IP address must be on a different subnet from the management interface. This configuration enables you to manage the controller directly or through a dedicated management network to ensure service access during network downtime.

Step 5 If you entered static in Step 4, enter the IP address and netmask for the service-port interface on the next two lines.

Service Interface IP Address: 172.19.30.18
Service Interface Netmask: 255.255.254.0
 
   

Step 6 Enter the IP address, netmask, default router IP address, optional VLAN identifier (a valid VLAN identifier or 0 for an untagged VLAN), and the port number for the management interface.


Note The VLAN identifier should be set to match the switch interface configuration.
Management Interface IP Address: 192.168.1.10
Management Interface Netmask: 255.255.0.0
Management Interface Default Router: 192.168.1.1
Management Interface VLAN Identifier (0 = untagged): 192
Management Interface Port Num [1 to 2]: 1
 
   

Step 7 Enter the IP address of the default DHCP server that will supply IP addresses to clients, the controller's management interface.

Management Interface DHCP Server IP Address: 192.168.1.1
 
   

Note The management interface is the default interface for in-band management of the controller and connectivity to enterprise such as AAA servers.

Step 8 Enter the IP address of the controller's virtual interface, which will be used by all controller Layer 3 security and mobility managers. You should enter a fictitious, unassigned IP address, such as 1.1.1.1.

Virtual Gateway IP Address: 1.1.1.1

Note The virtual interface is used to support mobility management, DHCP relay, and embedded Layer 3 security such as guest web authentication and VPN termination. All controllers within a mobility group must be configured with the same virtual interface IP address.

Step 9 If desired, enter the name of the mobility group/RF group to which you want the controller to belong.

Mobility/RF Group Name: amb
 
   

Note Although the name that you enter here is assigned to both the mobility group and the RF group, these groups are not identical. Both groups define clusters of controllers, but they have different purposes. All of the controllers in an RF group are usually also in the same mobility group and vice versa. However, a mobility group facilitates scalable, system-wide mobility and controller redundancy while an RF group facilitates scalable, system-wide dynamic RF management.

Step 10 Enter the network name, or service set identifier (SSID). The initial SSID enables basic functionality of the controller and allows access points that have joined the controller to enable their radios.

Network Name (SSID): amb
 
   

Step 11 Enter yes to enable DHCP proxy or no to disable DHCP proxy.

Configure DHCP Bridging Mode [yes][NO]:yes
 
   

Step 12 Enter yes to allow clients to assign their own IP address or no to make clients request an IP address from a DHCP server.

Allow Static IP Addresses [YES][no]:
 
   

Step 13 To configure a RADIUS server now, enter yes and then enter the IP address, communication port, and secret key of the RADIUS server. Otherwise, enter no.

Configure a RADIUS Server now? [YES][no]: no
Warning! The default WLAN security policy requires a RADIUS server.
Please see documentation for more details.
 
   

Step 14 Enter the code for the country in which the controller will be used.

Enter Country Code list (enter 'help' for a list of countries) [US]:
 
   

Note Enter help to view the list of available country codes.

Step 15 Enter yes to enable or no to disable each of the 802.11b, 802.11a, and 802.11g lightweight access point networks.

Enable 802.11b Network [YES][no]:
Enable 802.11a Network [YES][no]:
Enable 802.11g Network [YES][no]:

Note 802.11n is always enabled.
 
   

Step 16 Enter yes to enable or no to disable the controller's radio resource management (RRM) auto RF feature.

Enable Auto-RF [YES][no]:
 
   

Note The auto RF feature enables the controller to automatically form an RF group with other controllers. The group dynamically elects a leader to optimize RRM parameter settings, such as channel and transmit power assignment, for the group.

Step 17 If you want the controller to receive its time setting from an external Network Time Protocol (NTP) server when it powers up, enter yes to configure an NTP server. Otherwise, enter no.

Configure a NTP server now? [YES][no]: no
 
   

Step 18 If you entered no in the previous step and want to manually configure the system time on your controller now, enter yes. If you do not want to configure the system time now, enter no.

Configure the system time now? [YES][no]:
 
   

Step 19 If you entered yes in the previous step, enter the current date in MM/DD/YY format and the current time in HH:MM:SS format.

Enter the date in MM/DD/YY format: 03/28/11
Enter the time in HH:MM:SS format: 14:36:30
 
   

Step 20 When prompted to verify that the configuration is correct, enter yes or no.

Configuration correct? If yes, system will save it and reset. [yes][NO]: yes
 
   

The controller saves your configuration, reboots, and prompts you to log in.

Configuration saved!

Follow these steps to log into the controller.


Step 1 Enter a valid username and password to log into the controller CLI.


Note The administrative username and password you created in the Startup Wizard are case sensitive.

Step 2 The CLI displays the root level system prompt:

#(system prompt)> 
 
   

The system prompt can be any alphanumeric string up to 31 characters. You can change it by entering the config prompt command.


Note The CLI automatically logs you out without saving any changes after 5 minutes of inactivity. You can set the automatic logout from 0 (never log out) to 160 minutes using the config serial timeout command.

Note Cisco Aironet lightweight access points do not connect to the Cisco Flex 7500 Series Wireless Controller if the date and time are not set properly. Set the current date and time on the controller before allowing the access points to connect to it.

Verifying Interface Settings and Port Operation

Follow these steps to verify that your interface configurations have been set properly and the controller's ports are operational.


Step 1 Enter show interface summary. The controller's current interface configurations appear:

 
   
Interface Name                    Port  Vlan Id   IP Address      Type     Ap Mgr  Guest
--------------------------------  ----  --------  --------------  -------  ------- -----
management                        1     192       192.168.1.10    Static   Yes     No
service-port                      N/A   N/A       172.19.30.18    Static   No      No
virtual                           N/A   N/A       1.1.1.1         Static   No      No
 
   

Step 2 Enter show port summary. The following information appears, showing the status of the controller's distribution system ports, which serve as the data path between the controller and Cisco lightweight access points and to which the controller's management interface is mapped.

           STP   Admin   Physical   Physical    Link   Link 
Pr  Type   Stat   Mode     Mode      Status    Status  Trap   POE
-- ------- ---- ------- ---------- ---------- ------ ------- -------
1  Normal  Forw  Enable  Auto       10000 Full  Up     Enable N/A
2  Normal  Forw  Enable  Auto       10000 Full  Up     Enable N/A
 
   

A link status of Up indicates that the controller's ports are fully operational.


Connecting the Network (Distribution System)

The SFP+ module supported by the Cisco Flex 7500 Series Wireless Controller is the Cisco SFP-10G-SR.

Cisco SFP-10G-SR: The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF(OM3), up to 300m link lengths are possible.

Depending on the distribution system physical port to be assigned, use only standard compliant fiber-optic cables to connect the network equipment to the controller


Note Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section.

Connecting the Controller's Service Port (Optional)

The service port is controlled by the service-port interface and is reserved for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. The service-port interface enables the controller to be managed on an interface different from the one used for your network traffic. Use of the service port is optional.

You can perform out-of-band controller management from a PC running a terminal emulation program or a PC running Cisco WCS, a network management tool that enables you to configure and monitor a network of controllers, or the controller GUI. However, you must first connect the PC to the controller's service port in one of two ways:

Use an Ethernet cross-over cable to connect the PC directly to the controller's service port.

For a remote connection (using Telnet or SSH) through a dedicated management network, use a Category 5, Category 5e, Category 6, or Category 7 Ethernet cable to connect the management network to the controller's service port and the appropriate cable to connect the PC to the management network.

Connecting Access Points

After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7 Ethernet cables to connect Cisco lightweight access points to the network.

As soon as the controller is operational, it starts to scan for access points. When it detects an access point, it records the access-point MAC address in its database. The controller radio resource management (RRM) feature then automatically configures the access point to start sending and allowing clients to associate.

You have prepared the controller for basic operation. Refer to the Cisco Wireless LAN Controller Configuration Guide, Release 7.0, for information on configuring the controller to meet the specific needs of your wireless network.


Note The Cisco Flex 7500 Series Wireless Controller only supports Cisco H-REAP access points and Cisco Aironet access points operating in monitor mode. No other Cisco access points are supported by the Cisco Flex 7500 Series Wireless Controller.
