Switch Installation
Box Contents

◦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.
•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.
•For switches with the optional 1025-W power-supply module, first rack-mount the switch before installing
the power-supply module.
•Make sure power-supply modules are securely inserted in the chassis before moving the switch.
•When connecting or disconnecting the power cord on a switch that is installed above or below a 1025-W
power supply-equipped switch, you might need to remove the module from the switch to access the
power cord.
•Airflow around the switch and through the vents is unrestricted.
•For the Catalyst 2960X-24PSQ-L switches: Allow these clearances:
•Top and bottom: 1.75 in. (44.44 mm)
•Back of switch: 3 in. (76.19 mm)
•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.

Switch Installation
Verifying Switch Operation

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.
When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode during
normal operation.

Stack Bandwidth and Partitioning Examples

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.
Figure 10: Partitioned Stack with a Failover Condition
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 or Catalyst 2960-XR Switch Stacking Configuration Guide on
Cisco.com.
