Maintenance and Upgrades

Graceful Shut Down

The appliance can run in two power modes:

  • Main power mode—Power is supplied to all appliance components and the operating system.

  • Standby power mode—Power is supplied only to the service processor and the cooling fans. It is safe to power off the appliance from this mode.

Before you begin

You can gracefully shut down the appliance by using the shutdown command or the Power button on the appliance front panel.

Procedure

Step 1

Check the color of the Power Status LED (see Front Panel).

  • Amber—The appliance is already in standby mode and can be safely powered off. Go to Step 3.

  • Green—The appliance is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.

Step 2

Use one the following methods to shut down the appliance. If possible, invoke a graceful shutdown. Otherwise invoke a hard shutdown:

Caution 

To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.

  • Graceful shutdown using the CLI—Enter the shutdown command. The operating system performs a graceful shutdown and the appliance goes to standby mode, which is indicated by an amber Power Status LED.

  • Graceful shutdown using the front panel—Press and release the Power button. The operating system performs a graceful shutdown and the appliance goes to standby mode, which is indicated by an amber Power Status LED.

  • Emergency shutdown—Press and hold the Power button for four seconds to force the main power off and immediately enter standby mode.

Step 3

Disconnect the power cords from the power supplies in your appliance to completely power off the appliance.

Replace Components Guidelines


Warning

Statement 1029—Blank Faceplates and Cover Panels

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.


Caution

When handling appliance components, wear an ESD strap to avoid damage.

Tip

You can press the Unit Identification button on the front panel or rear panel to turn on a flashing Unit Identification LED on the front and rear panels of the chassis. This button allows you to locate the specific chassis that you are servicing when you go to the opposite side of the rack. For locations of these LEDs, see Front Panel.

Remove and Replace the Power Supply

The two power supplies included with your chassis are redundant and hot-swappable. One is the active power supply and the other is the standby power supply (1+1).

This chassis also supports cold redundancy. Depending on the power being drawn by the chassis, one power supply might actively provide all power to the system while the remaining power supply is put into a standby state. For example, if the power consumption can be satisfied by power supply 1, then power supply 2 is put into a standby state.


Caution

When you replace power supplies, do not mix power supply types in the appliance. Both power supplies must be the same wattage and Cisco PID.

Before you begin

Take note of the following warnings:


Warning

Statement 1018—Supply Circuit

Take care when connecting units to the supply circuit so that wiring is not overloaded.


Warning

Statement 1019—Main Disconnecting Device

The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device.


Warning

Statement 1024—Ground Conductor

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.


Warning

Statement 1030—Equipment Installation

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.


Warning

Statement 1030—Equipment Installation

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.


Warning

Statement 1073—No User-Serviceable Parts

No user-serviceable parts inside. Do not open.

Warning

Statement 1074—Comply with Local and National Electrical Codes

Installation of the equipment must comply with local and national electrical codes.

Procedure

Step 1

Remove the power supply that you are replacing:

  1. Remove the power cord from the power supply.

  2. Grasp the power supply handle while pinching the green release lever towards the handle.

  3. Pull the power supply out of the bay.

Step 2

Install a new power supply:

  1. Grasp the power supply handle and insert the new power supply into the empty bay.

  2. Push the power supply into the bay until the release lever locks.

  3. Connect the power cord to the new power supply.

  4. If you shut down the chassis, press the Power button to return the chassis to main power mode.

Remove and Replace the Drive


Tip

We recommend that you shut down or power off the chassis to replace the drives even though they are hot-swappable. If you do not turn power off while replacing the drive, you should restart the chassis afterward.


Note

You cannot add more drives to your FMC. You can only replace the drives in the slots that are supported for your model.
