Installation Guidelines Chapter 3 Power Supply and Fan Module Installation • The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing mode, removing a power supply causes powered devices to shut down until the power budget matches the input power of a single power supply. To minimize network interruption, hot swap the power supply under these circumstances: - The switch is connected to an XPS 2200 and sufficient power is available. - The switch is in StackPower mode and sufficient power is available (Catalyst 3750-X only). - The switch is powered by other switches in a power stack, and no active backup is in progress. For the switch commands for displaying the available power budget, see the Catalyst 3750-X and 3560-X Software Configuration Guide. Caution Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both module slots must be populated, with either a power supply or a blank module. Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 • The switch supports hot swapping of a fan module. When replacing a fan, you should complete the replacement procedure within 5 minutes to avoid overheating the switch. • The switch continues to operate when there is one failed chassis cooling fan. If one fan fails, the switch sends an error message. If a second fan fails, the switch sends an error message, writes a failure log to flash memory, and shuts down. • Make sure that all power supply and fan modules are securely seated before moving the switch. Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Power Supply and Fan Module Installation
Installation Guidelines
•
The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing
mode, removing a power supply causes powered devices to shut down until the power budget
matches the input power of a single power supply. To minimize network interruption, hot swap the
power supply under these circumstances:
–
The switch is connected to an XPS 2200 and sufficient power is available.
–
The switch is in StackPower mode and sufficient power is available (Catalyst 3750-X only).
–
The switch is powered by other switches in a power stack, and no active backup is in progress.
For the switch commands for displaying the available power budget, see the
Catalyst 3750-X and
3560-X Software Configuration Guide
.
Caution
Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both
module slots must be populated, with either a power supply or a blank module.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Warning
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
