Maintenance and Upgrades

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.


Caution
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.

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

Procedure

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:

Caution

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

  • 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.

  • 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.

Procedure

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

See Reset the Chassis Remotely for the procedure for configuring remote chassis management.

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 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.

Procedure

Step 1

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

Note

 

The RPC port must be configured with the required credentials. See Enable RPC for more information.

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.

Procedure

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.

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

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).


Note

The Secure Web Appliance S196 ships with one power supply, but you can add another one for redundancy.

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.


Caution

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.


Trouble

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.
