Power Button Shut Down

The chassis runs in two modes:

• Main power mode—Power is supplied to all components and all operating systems can run.

• Standby power mode—Power is supplied only to the service processor and certain components. You can

safely remove power cords from the chassis in this mode.

After you shut down the chassis to standby power, electric current is still present in the chassis. To completely

remove power as directed in some maintenance procedures, you must disconnect all power cords from all

power supplies in the chassis.

Caution

You can shut down the chassis using the front panel Power button or software management.

Step 1 Check the Power LED:

• Amber—The chassis is already in standby mode and you can safely remove power.

• Green—The chassis is in main power mode and you must shut it down before you can safely remove power.

Step 2 Perform a graceful shutdown or a hard shutdown:

To avoid data loss or damage to your operating system, perform a graceful shutdown of the operating system.

Caution

• Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and

the chassis goes into standby mode. The power LED is amber.

Maintenance and Upgrade

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

enter standby mode.

Step 3 If a maintenance procedure instructs you to completely remove power from the chassis, disconnect all power cords from

the power supplies.

Enable RPC

You must enable and configure RPC before you can remotely reset chassis power.

Before you begin

• Cable the RPC port directly to a secure network.

• Open necessary ports through the firewall to make sure the chassis is accessible remotely.

• RPC requires a unique IPv4 address for the RPC port. You must use the following procedure to configure

the RPC port. You cannot configure it using the ipconfig command.

•To cycle chassis power you must have a third-party tool that supports the Intelligent Platform Management

Interface (IPMI) version 2.0.

Step 1 Use SSH or the serial console port to access the CLI.

Step 2 Log in using an account with Administrator access.

Step 3 Enter the following commands:

remotepower

setup

Step 4 Follow the prompts to specify the following:

• The dedicated IP address for the RPC port, netmask, and gateway.

• The username and password required to execute the power-cycle command.

These credentials are independent of other credentials used to access your appliance. Store this information for

administrators who may need to set up RPC in the future.

Step 5 Enter commit to save your changes.

Step 6 Test your configuration to verify that you can remotely manage chassis power.

What to do next

Reset the Chassis Remotely, on page 3

Maintenance and Upgrade

Enable RPC

Reset the Chassis Remotely

If the chassis requires a hard reset, you can reboot the chassis remotely using a third-party IPMI tool.

Before you begin

• You must enable RPC in advance. See Enable RPC, on page 2 for the procedure.

• Only the following IPMI commands are supported. Refer to your IPMI tool documentation on how to

use them.

status, on, off, cycle, reset, diag, soft

• Set up a utility that can manage devices using IPMI version 2.0.

Step 1 Use IPMI to issue a supported power-cycling command to the IP address assign to the RPC port.

The RPC port must be configured with the required credentials. See Enable RPC, on page 2 for more

information.

Note

For example, issue the following command from a UNIX computer with IPMI support:

ipmitool -I lan -H ip-address -U remoteresetuser -P password chassis power reset

Step 2 Wait at least 11 minutes for the chassis to reboot.

Install/Uninstall the Locking Faceplate

The locking faceplate (Cisco part number 74-115098-01 for a 1 RU chassis and Cisco part number 74-115099-01

for a 2 RU chassis) ships with the key you need to lock the faceplate to the front panel of the chassis. The

locking faceplate clicks in between the two side handles on the front panel.

Step 1 Insert the right side of the locking faceplate by aligning the two plastic tabs with the two cutouts on the right side handle

on the front of the chassis.

Step 2 Press in the left side of the faceplate into the left side handle on the front panel. The tabs are spring-mounted to the latch,

so they push in as the faceplate is installed.

Step 3 Lock the faceplate using the key that shipped with the faceplate.

Step 4 To uninstall the faceplate, unlock the faceplate, push the latch to the right, and pull the faceplate out.

Remove and Replace a Drive

The drives are hot-swappable. You do not have to shut down the chassis to remove or replace drives.

Note

Maintenance and Upgrade

Remove and Replace a Drive

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

your model.

Note

Before you begin

Statement 1018—Supply Circuit

To reduce risk of electric shock and fire, 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. To reduce the risk of electric shock, 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 1073—No User-Serviceable Parts

No serviceable parts inside. To avoid risk of electric shock, do not open.

Warning

Statement 1074—Comply with Local and National Electrical Codes

To reduce risk of electric shock or fire, installation of the equipment must comply with local and national

electrical codes.

Warning

Step 1 Remove the drive that you are replacing:

a) Press the release button on the face of the drive tray.

b) Grasp and open the ejector lever and then pull the drive tray out of the slot.

Step 3 Install a new drive:

a) Place a new drive in the empty drive tray and install the four drive-tray screws.

b) With the ejector lever on the drive tray open, insert the drive tray into the empty drive bay.

c) Push the tray into the slot until it touches the backplane, and then close the ejector lever to lock the drive in place.

Remove and Replace a Power Supply

Two power supplies ship with the chassis; they are redundant and hot-swappable. One is the active power

supply and the other is the standby power supply (1+1).

The C195 ships with one power supply, but you can add another one for redundancy.

Note

The 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.

When you replace power supplies, do not mix power supply types in the chassis. Both power supplies must

be the same wattage and Cisco PID.

Caution

Power supply health monitoring notifies you if the power supply loses power or malfunctions so that redundancy

is lost. Check the power supply cables to make sure they are functioning. If they are and errors are still

occurring, replace the power supply.
