Tools and Equipment
Obtain these necessary tools and equipment:
A number-2 Phillips screwdriver to rack-mount the switch.
Installation Guidelines
When determining where to install the switch, verify that these guidelines are met:
Clearance to the switch front and rear panel meets these conditions:
Front-panel LEDs can be easily read.
Access to ports is sufficient for unrestricted cabling.
AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
Access to the rear of the rack is sufficient for connecting FlexStack cables to stacked switches, or connecting the optional Cisco Redundant Power Supply (RPS) 2300.
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
Airflow around the switch and through the vents is unrestricted.
Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.
Humidity around the switch does not exceed 95 percent.
Altitude at the installation site is not greater than 10,000 feet.
For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328 feet (100 meters).
Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing contaminant buildup inside the chassis, which can result in system malfunction. You must install this equipment in an environment as free from dust and foreign conductive material (such as metal flakes from construction activities) as is possible.
Verifying Switch Operation
Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that it passes POST.
To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug the other end into 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. When the switch begins POST, the SYST, RPS, STAT, and SPEED LEDs turn green. The SYST LED blinks green, and the other LEDs remain solid green.
When the switch completes POST successfully, the SYST LED remains green. The RPS LED remains green for some time and then reflects the switch operating status. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the SYST LED turns amber.
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
After a successful POST, unplug the power cord from the switch and install the switch in a rack, on a wall, on a table, or on a shelf.
If your configuration has an RPS, connect the switch and the RPS to different AC power sources. See the Cisco RPS documentation for information.
Note
When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode during normal operation.
Warning
Attach only the following Cisco external power system to the switch: PWR-RPS2300 Statement 387
Planning and Installing a Switch Stack (Optional)
Note
This section applies only to the Catalyst 2960-X stacking-capable switches.
Connect only Catalyst 2960-X or 2960-S switches in a mixed switch stack.
Note
You can only create mixed stacks with Catalyst 2960-X or 2960-S switches (up to four switches). You cannot create mixed stacks with other switches.
Install the FlexStack-Plus module and the FlexStack cable.
Note
The FlexStack-Plus module is hot-swappable and can be inserted while the switch is powered on.
Order the appropriate cable from your Cisco sales representative. The length of FlexStack cable depends on your configuration. These are the different sizes available:
CAB-STK-E-0.5M= (0.5-meter cable)
CAB-STK-E-1M= (1-meter cable)
CAB-STK-E-3M= (3-meter cable)
Make sure that you have access to the switch rear panel and to the rear of the rack.
Installing the FlexStack-Plus Module
Note
The switch should always have a blank module installed when a FlexStack-Plus module is not used.
The Catalyst 2960X-48P-L switch is shown as an example. You can install the module in other switches as shown.
Procedure
Step 1
Use a number 2 Phillips-head screwdriver to remove the FlexStack-Plus module blank cover on the switch back panel.
Step 2
Grasp the FlexStack-Plus module on the sides, and insert it into the module slot. Push the module in completely until you feel it snap into place.
Step 3
Secure the screws on each side of the module.
Note
Avoid overtightening the screws.
Stack Cabling
Figure 1. Stacking Switches with the 0.5-meter FlexStack Cable. These figures show the switches stacked in a vertical rack or on a table. The connections are redundant.
Figure 2. Stacking Switches with 0.5-meter and 3-meter FlexStack Cables
Stack Bandwidth and Partitioning Examples
Figure 3. Stack with Full Bandwidth Connections. This figure shows a stack that provides full bandwidth with redundant connections.
Figure 4. Stack with Half Bandwidth Connections. This figure shows a stack with incomplete stack cabling connections. This stack provides only half bandwidth and does not have redundant connections.
Figure 5. Stack with a Failover Condition. This figure shows a stack with a bad FlexStack cable in link B. This stack provides only half bandwidth and does not have redundant connections.
Figure 6. Partitioned Stack with a Failover Condition. This figure shows a stack with a bad link B. This stack partitions into two
stacks, and switch 1 and
switch 3 are stack masters.
Power-On Sequence for Switch Stacks
Consider these guidelines before you power on the switches in a stack:
The sequence in which the switches are first powered on might affect the switch that becomes the stack master.
If you want a particular switch to be the stack master, power on that switch first. This switch becomes the stack master and remains the stack master until a master reelection. After 2 minutes, power on the other stack switches.
If you have no preference as to which switch becomes the stack master, power on all the switches in the stack within a 1-minute timeframe. These switches participate in the stack master election. Switches powered on after the 1-minute timeframe do not participate in the election.
Power off a switch before you add it to or remove it from an existing switch stack.
For conditions that can cause a stack master reelection or to manually elect the stack master, see the Catalyst 2960-X Switch Stacking Configuration Guide on Cisco.com.

Installing SFP and SFP+ Modules
Some switch models support SFP modules, SFP+ modules, or both. The SFP slots support only the SFP modules. The slots marked SFP+ slots support both SFP and SFP+ modules.
See the switch release notes on Cisco.com for the list of supported SFP modules. Use only Cisco SFP modules on the switch. Each Cisco module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the module meets the requirements for the switch.
For information about installing, removing, cabling, and troubleshooting SFP modules, see the module documentation that shipped with your device.
When installing SFP or SFP+ modules, observe these guidelines:
Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.
To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.
Caution
Removing and installing an SFP or SFP+ module can shorten its useful life. Do not remove and insert any module more often than is absolutely necessary.
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Find the send (TX) and receive (RX) markings on the module top.
On some SFP or SFP+ modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection.
Step 3
If the module has a bale-clasp latch, move it to the open, unlocked position.
Step 4
Align the module in front of the slot opening, and push until you feel the connector snap into place.
Step 5
If the module has a bale-clasp latch, close it.
Step 6
For fiber-optic SFP or SFP+ modules, remove the dust plugs and save.
Step 7
Connect the SFP cables.
Figure 17. Installing an SFP Module
Removing an SFP or SFP+ Module
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX).
Step 3
Insert a dust plug into the optical ports of the SFP or SFP+ module to keep the optical interfaces clean.
Step 4
If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the latch is obstructed and you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument to open the latch.
Step 5
Grasp the SFP or SFP+ module, and carefully remove it from the module slot.
Step 6
Place the module in an antistatic bag or other protective environment.
Do not remove the rubber plugs from the SFP or SFP+ module 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 module ports and cables from contamination and ambient light. Before connecting to the SFP module, be sure that you understand the port and cabling stipulations.
Procedure
Step 1
Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
Step 2
Insert one end of the fiber-optic cable into the SFP or SFP+ module port.
Step 3
Insert the other cable end into a fiber-optic receptacle on a target device.
Figure 18. Connecting to a Fiber-Optic SFP Module Port

LC connector
Step 4
Observe the port status LED.
The LED turns green when the switch and the target device have an established link.
The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.
If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device.
When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.
Note
The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference on Cisco.com.
Caution
To prevent ESD damage, follow your normal board and component handling procedures.
Procedure
Step 1
Connect one end of the cable to the SFP module port. Insert a four twisted-pair, straight-through cable when you connect to servers, workstations, and routers. Insert a four twisted-pair, crossover cable when you connect to switches or repeaters.
Step 2
Connect the other end of the cable to an RJ-45 connector on the other device.

Step 3
Observe the port status LED.
The LED turns green when the switch and the other device have an established link.
The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.
If the LED is off, the other device might not be turned on, there might be a cable problem, or there might be a problem with the adapter in the other device.
Step 4
If necessary, reconfigure and restart the switch or other device.
10/100/1000 PoE+ Port Connections
The ports provide PoE support for devices compliant with IEEE 802.3af and 802.3at (PoE+), and also provide Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power when an IP phone or an access point is connected.
You can use this application to calculate the power supply requirements for a specific PoE configuration. The results show output current, output power, and system heat dissipation.
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072
Caution
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch or other devices.
Caution
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at (PoE+)-compliant devices. You must remove any cable or device that causes a PoE fault.
Procedure
Step 1
Connect one end of the cable to the switch PoE port.
Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both devices have established link.
The port LED is amber while STP discovers the topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green. If the LED is off, the other device might not be turned on, there might be a cable problem, or there might be a problem with the adapter in the other device.
Step 3
Reconfigure and reboot the connected device if needed.
Step 4
Repeat Steps 1 through 3 to connect each device.
Note
Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.
10/100/1000 Port Connections
The switch 10/100/1000 port configuration changes to operate at the speed of the attached device. If the attached ports do not support autonegotiation, you can manually set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
Let the ports autonegotiate both speed and duplex.
Set the interface speed and duplex parameters on both ends of the connection.
The autonegotiation and the auto-MDIX features are enabled by default on the switch.
With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If the attached device does not support autonegotiation, you can manually set the switch interface speed and duplex parameters.
With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly.
If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.
