Power Button Shut Down
The Threat Grid M5 runs in two modes:
• Main power mode—Power is supplied to all Threat Grid M5 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 Threat Grid M5 in this mode.
After you shut down the Threat Grid M5 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 on the Threat Grid M5.
Caution
You can shut down the Threat Grid M5 using the front panel Power button or use OpAdmin to initiate a reboot
or shutdown.
Step 1 Check the Power LED:
• Amber—The Threat Grid M5 is already in standby mode and you can safely remove power.
• Green—The Threat Grid M5 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 Threat Grid M5 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 Threat Grid M5, disconnect all power
cords from the power supplies.
Remove and Replace a Drive
The drives are hot-swappable. You do not have to shut down the Threat Grid M5 to remove or replace drives.
Note
You cannot add more drives to the chassis. You can only replace the drives in the slots that shipped with your
Threat Grid M5.
Note
Before you begin
Take note of the following warnings:
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 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.

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
The Threat Grid M5 ships with two power supplies, which are redundant and hot-swappable. One is the active
power supply and the other is the standby power supply (1+1).
The Threat Grid M5 also supports cold redundancy. Depending on the power being drawn by the Threat Grid
M5, 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 Threat Grid M5. Both power supplies
must be the same wattage and Cisco PID.

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.
