Tools and Equipment
Obtain these necessary tools:
• A Number-2 Phillips screwdriver.
Verifying Switch Operation
Before you install the switch in a rack, 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. The SYST LED blinks green, and the other LEDs remain
solid green.
When the switch completes POST successfully, the SYST LED remains green. 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 table,
or on a shelf.
Attach only the following Cisco external power system to the switch: Cisco XPS 2200 Statement 387

Planning a Switch Data Stack
Cisco Catalyst 9300 switches can share bandwidth by using data stacking. The following table lists the
supported stacking options:
Table 1: Supported Stacking Options
Supported BandwidthStacking OptionSwitch Model

Tools and Equipment

Mixed stacking between C9300X and C9300 switches are supported at StackWise-480 speed. However, you
cannot stack fixed uplink switches with modular uplink switches or other Cisco Catalyst switches.
Switch Stacking and Power Stacking Guidelines
Before connecting the switches in a stack, ensure that you read these stacking guidelines:
• Size of the switch and any optional power supply module. The 1100 W/1900 W power supply module
is longer than the other modules. Stacking switches with the same power supply modules together makes
it easier to cable the switches.
• Length of cable. Depending on the configurations that you have, you might need different sized cables.
If you do not specify the length of the StackWise cable, the 0.5 meter cable is supplied. If you need the
1 meter cable or the 3 meter cable, you can order it from your Cisco supplier. For cable part numbers,
see StackWise Accessories. The Data Stack Cabling Configurations, on page 4 provides examples of
recommended configurations.
• For rack mounted switch stacks that are members of a StackPower stack as well as a data stack, see
Planning a StackPower Stack, on page 7.
• Up to four switches can be configured in a StackPower stack using the StackPower connector at the rear
of the switch. However, with XPS-2200, you can configure up to nine C9300 switches in a StackPower
stack. Currently, C9300X switches do not support XPS-2200.
Data Stack Cabling Configurations
This is an example of a recommended configuration that uses the supplied 0.5-meter StackWise cable. In this
example, the switches are stacked in a vertical rack or on a table. This configuration provides redundant
connections. The configuration example uses the supplied 0.5-meter StackWise cable. The example shows
the full-ring configuration that provides redundant connections.
Figure 2: Data Stacking the Switches in a Rack or on a Table Using the 0.5-meter StackWise Cables
This example shows a recommended configuration when the switches are mounted side-by-side. Use the
1-meter and the 3-meter StackWise cables to connect the switches. This configuration provides redundant
connections.

Switch Stacking and Power Stacking Guidelines

Data Stack Bandwidth and Partitioning Examples
This section provides examples of data stack bandwidth and possible data stack partitioning. The figure shows
a data stack of switches that provides full bandwidth and redundant StackWise cable connections.
Figure 4: Example of a Data Stack with Full Bandwidth Connections
This figure shows an example of a stack of switches with incomplete StackWise cabling connections. This
stack provides only half bandwidth and does not have redundant connections.
Figure 5: Example of a Data Stack with Half Bandwidth Connections
The figures below show data stacks of switches with failover conditions. In this figure, the StackWise cable
is bad in link 2. Therefore, this stack provides only half bandwidth and does not have redundant connections.
Figure 6: Example of a Data Stack with a Failover Condition
In this figure, link 2 is bad. Therefore, this stack partitions into two stacks, and the top and bottom switches
become the active switch in the stack. If the bottom switch is a member (not active or standby switch), it
reloads.

Figure 7: Example of a Partitioned Data 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.
• There are two ways to elect an active switch:
• If you want a particular switch to become the active switch, configure it with the highest priority.
Among switches with same priority, the switch with the lowest MAC address becomes the active
switch.
• If you want a particular switch to become the active switch, power on that switch first. This switch
remains the active switch until a reelection is required. After 2 minutes, power on the other switches
in the stack. If you have no preference as to which switch becomes the active switch, power on all
the switches in the stack within 1 minute. These switches participate in the active switch election.
Switches powered on after 2 minutes do not participate in the election.
If changes are made to the stack without powering down the switches, the following results can occur:
• If two operating partial ring stacks are connected together using a stack cable, a stack merge can take
place. This situation reloads the whole stack (all switches in the stack).
• If some switches in the stack are completely separated from the stack, a stack split can occur.
• A stack split can occur on a full ring stack if:
• More than one running switch is removed without powering down.
• More than one stack cable is removed without powering down.
• A stack split can occur in a partial ring stack if:
• A switch is removed without powering down.
• A stack cable is removed without powering down.
• In a split stack, depending on where the active and standby switches are located, either two stacks might
be formed (with the standby taking over as the new active switch in the newly formed stack) or all the
members in the newly formed stack might reload.

Power-On Sequence for Switch Stacks

These results depend on how the switches are connected. You can remove two or more switches from the
stack without splitting the stack.
Note
For conditions that can cause a stack reelection or to manually elect the active switch, see the stacking software
configuration guide on Cisco.com at this URL: http://www.cisco.com/go/c9300.
Planning a StackPower Stack
StackPower Stacking Guidelines
You can configure a StackPower stack for either power sharing or redundancy. In power-sharing mode, the
power of all the power supplies in the stack is aggregated and distributed among the stack members.
In redundant mode, when the total power budget of the stack is calculated, the wattage of the largest power
supply is not included. That power is held in reserve and used to maintain power to switches and attached
devices when one power supply fails. Following the failure of a power supply, the StackPower mode becomes
power sharing.
Power-sharing mode is the recommended configuration for Cisco Catalyst 9300 Series Switches.
Note
For general concepts and management procedures for switch power stacks, see the Software Configuration
Guide on Cisco.com.
Before connecting the switches in a power stack, read the following guidelines:
• C9300 and C9300X switches support Cisco StackPower providing up to 1000 W of power in nominal
conditions and 2400 W of power in failure conditions across a power stack. Cisco StackPower is not
supported in C9300L switches.
• A switch power stack can include a maximum of four switches in a ring topology and nine switches in
a star topology. Currently, C9300X switches do not provide support for XPS-2200.
• Size of the switch and any optional power supply module. The 1100 W/1900 W power supply module
is 1.5 inches (3.81 cm) longer than the other modules, and with the attached cable retention clip, it extends
3 inches (7.62 cm) from the switch chassis. Stacking switches with the same power supply modules
together makes it easier to cable the switches. For switch dimensions, see Appendix A, “Technical
Specifications.”
• Length of cable. Depending on the configurations that you have, you might need different sized cables.
If you do not specify the length of the StackPower cable, the 0.3 meter cable is supplied. If you need the
1.5 meter cable, you can order it from your Cisco supplier. For cable part numbers, see StackPower
Connector. The StackPower Cabling Configurations, on page 8 provides examples of recommended
configurations.
• For rack mounted switch stacks that are members of a data stack and a StackPower stack, see Switch
Stacking and Power Stacking Guidelines, on page 4

StackPower Cabling Configurations
This section describes the recommended cabling configurations for a StackPower stack. There are two types
of StackPower cables.
The cable in the figure connects a switch to another switch in a power stack or with an XPS. StackPower
cables have color bands on the cable ends:
• The cable end with the green band can connect only to a switch.
• The cable end with the yellow band can connect to a switch or an XPS.
The cable is available in two lengths.

This figure shows a ring configuration using both of the supplied 0.3-meter StackPower cables and one
1.5-meter cable. In the examples that follow, the switches are stacked in a vertical rack or on a table.

StackPower Partitioning Examples
These figures show StackPower stacks of switches with failover conditions.
In the following figure, the StackPower cable 2 is faulty. This is considered a broken ring and is a fault
condition. Power is still shared across the stack, but this condition will place a limitation on power budgeting
and the number of high priority ports it can protect in the case of any further failures such as failure of power
supply, AC mains, StackPower port and so on. StackPower is not intended for secondary failures and hence
restoration of the failed component or power should be done immediately.

StackPower Partitioning Examples

Figure 11: Example of a StackPower Stack with a Failover Condition
In the following figure, StackPower port B on the center switch has failed and the stack partitions into two
stacks. The top two switches share power, and the bottom switch is now a separate stack. After initial failure
of cable 2, any further failure of a port is considered a double fault, which a StackPower cannot handle. A
double fault could result in unintended high priority ports being shut. If you are unable to physically restore
a bad cable, adjust port priorities and restore any offline supplies, as available.

Step 4 When you complete the switch installation, see After Switch Installation, on page 16for information on switch
configuration.
After Switch Installation
• Configure the switch using the Web User Interface. For more information, see "Configuring the Switch
Using the Web User Interface" topic in the Software Configuration Guide.
• Connect the StackPower and StackWise ports.
• Install the power cord retainer (optional).
• Connect the required devices to the switch ports.
• Turn on the power supply switches to power up the system. While powering up, the switch performs a
series of bootup diagnostic tests.
The switch is designed to boot up in less than 30 minutes, provided that the
neighboring devices are in fully operational state.
Note
• Verify port connectivity after connecting devices to the switch ports. The LED turns green when the
switch and the attached device have a link.
Connecting the StackWise Cables
Before connecting the StackWise cables, review the Planning a Switch Data Stack, on page 3. Always use
a Cisco-approved StackWise cable to connect the switches.
Connecting a StackWise-320 Cable
Procedure
Step 1 Remove the dust covers from the StackWise cables and store them for future use.
A StackWise adapter must be installed in the StackWise port to enable stacking. In a default setup, the
StackWise adapter blanks are installed in the StackWise ports. If StackWise is ordered with the switch,
StackWise adapters are already installed in the StackWise ports, and you can proceed to step 4.
Step 2 Remove the StackWise adapter blanks from each destination StackWise port using the Torx T15 Allen key
provided in the stacking kit (or a Torx T15 screwdriver). Store them for future use.
Step 3 Install the StackWise adapter in each destination StackWise port, and secure it in place using the supplied
Torx T15 key, or a Torx T15 screwdriver.

Connecting to the StackPower Ports
Before you begin
Before connecting the StackPower cables, review Planning a Switch Data Stack, on page 3. Always use a
Cisco-approved StackPower cable to connect the switches. To prevent misconfiguration, the StackPower ports
on the switch are keyed and have colored bands that match the keying and bands on the StackPower cable
connectors.
Procedure
Step 1 Remove the dust covers from the StackPower cable connectors.
Step 2 Connect the end of the cable with a green band to either StackPower port on the first switch. Align the connector
correctly, and insert it into a StackPower port on the switch rear panel.
Step 3 Connect the end of the cable with the yellow band to another switch (to configure StackPower power sharing).
Step 4 Hand-tighten the captive screws to secure the StackPower cable connectors in place.
Removing and installing the StackPower cable can shorten its useful life. Do not remove and insert
the cable more often than is absolutely necessary.
