Defining custom alerts
The /etc/alertd/alert.conf and the /config/user_alert.conf files on the BIG-IP system define alerts
that cause the indicators to change. The /etc/alertd/alert.conf file defines standard system alerts, and the
/config/user_alert.conf filedefines custom settings.You should editonly the /config/user_alert.conf
file.
1. Open a command prompt on the BIG-IP system.
2. Type the following command:
10 | Platform Guide: 3900

cd /config
3. Using a text editor, such as vi or Pico, open the /config/user_alert.conf file.
4. Add the following lines to the end of the file:
alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_DOWN "Pool member (.*?):(.*?) monitor
status down."
{
snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.10";
lcdwarn description="Node down" priority="1"
}
alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_DOWN "Node (.*?) monitor status

snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.12";
lcdwarn description="Node address down" priority="1"
}
alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_UP "Pool member (.*?):(.*?) monitor
status up."
{
snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.11"
}
alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_UP "Node (.*?) monitor status up."
{
snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.13"
}
5. Save the file and exit the text editor.
The front panel LEDs now indicate when a node is down.
Additional indicator LED status conditions
A few LED status conditions are not covered in the definition tables in the /etc/alertd/alert.conf file.
Yellow intermittent status LED indicator
A yellow intermittent status LED indicates that the unit is not under host computer control. This might be due to the
host being halted or due to a software or hardware problem that interferes with the host’s control of the LED.
Green/Yellow solid status LED indicator
When the status LED indicator is solid yellow or green, it indicates that the BIG-IP unit is in a Standby state (yellow)
or anActive state (green). It displays solid green if the unit is Standalone or if it is theActive unit of a redundant system
configuration. It displays yellow if the unit is the Standby member of a redundant system configuration.
Platform Interfaces
You can perform configuration tasks such as displaying interface status and settings and setting the media type using
either the Traffic Management Shell (tmsh) or the bigpipe utility.
When using the bigpipe interface command or the tmsh interface command, you can either apply the command
to all interfaces or to a specific interface key.
Viewing the status of a specific interface
You can use bigpipe or tmsh to view the status of a specific interface on a platform.
From the command line interface, use the following syntax to display the current status of a specific interface:

About interface media type and duplex mode
All interfaces on the BIG-IP system default to auto-negotiate speed and duplex settings. We recommend that you also
configure any network equipment that you plan to use with the BIG-IP system to auto-negotiate speed and duplex
settings. If you connect the BIG-IP system to network devices with forced speed and duplex settings, you must force
the speed and duplex settings of the BIG-IP system to match the settings of the other network device.
Important: If the BIG-IP system is attempting to auto-negotiate interface settings with an interface that has the
speed and duplex settings forced, you will experience severe performance degradation.
By default, the media type on interfaces is set to automatically detect speed and duplex settings, but you can specify a
media type. Use the following syntax to set the media type: b interface <interface_key> media <media
type> | auto.
If the media type does not accept the duplex mode setting, a message indicates this. If media type is set to auto, or if the
interface does not accept the duplex mode setting, the duplex setting is not saved to the /config/bigip_base.conf
file.
Important: If you manually configure the platform to use specific speed and duplex settings on interfaces, Auto
MDI/MDIX functionality is turned off by default. Additionally, when an interface is set manually, it functions as
a data terminal equipment (DTE) port. This means that crossover cables are required to connect to other DTE
devices (for example, servers), and straight-through cables are required for connecting to data communications
equipment (DCE) devices (for example, switches or routers). Be sure to use the correct cable type (straight-through
or crossover) if you manually set interface speed and duplex settings.
Viewing valid media types for an interface
This platform may not support all of the media type options that are available in bigpipe and tmsh.You can use bigpipe
or tmsh to view the valid media types for an interface.
From the command line interface, use the following syntax to display the valid media types for a specific interface:
b interface <interface_key> media show
Important: In all Gigabit Ethernet modes, the only valid duplex mode is full duplex.

Always-On Management
TheAlways-On Management (AOM) subsystem enables you to manage the BIG-IP system remotely using SSH or serial
console, even if the host is powered down. TheAOM Command Menu operates independently of the BIG-IP®Traffic
Management Operating System®(TMOS) through the management port, the serial port console, and remotely through
the traffic management ports.You can use the command menu to reset the unit if TMOS®has locked up.You can also
get console access to the Traffic Management Operating System itself, so that you can configure TMOS from the
command line interface.
AOM consists of the host console shell (hostconsh), the shell that provides access to the command menu, and the
Command Menu, which contains the options for AOM.

Platform Installation
After you have reviewed the hardware requirements and become familiar with
the 3900 platform, you can install the unit.
Topics:
•Determine which rail kit to use
•General recommendations for
rack mounting
•About the front-mounting kit
•About the rail-mounting kit
•Connecting the cables and other
hardware

Determine which rail kit to use
The 3900 platform comes with two types of rack mounting kits: stationary front-mounting and sliding rail-mounting.
An advantage of installing the sliding rail-mounting kit is that you can then slide the unit in and out of the rack as needed.
The tasks you need to perform to install the platform differ, depending on the type of rack mount you decide to use or
which type of cabinet unit you are installing into (single two-post cabinet or four-post cabinet).
General recommendations for rack mounting
Although not required, a 1U space between units makes it easier for you to remove the unit from the rack if that the unit
requires service. A 1U space between units also provides additional cable routing options.
We recommend 100 mm spacing from the front panel of the unit to the rack front or rack door. This provides enough
room for you to route the cables without excessive bending or insulation damage.
A shelf or similar device is required to support the unit if only one person is installing the unit.
Caution: To prevent personal injury or damage to the unit, we recommend that at least two people perform the
installation.
Caution: This product is sensitive to electrostatic discharge (ESD). We recommend that you use proper ESD
grounding procedures and equipment when you install or maintain the unit.
Caution: Do not power on the platform until the management serial console or the management network is
connected to the unit.
About the front-mounting kit
You can use the front-mounting kit if you are installing into a two-post cabinet.
Front-mounting kit hardware
The front-mounting kit includes these parts.
HardwareQuantity
front-mounting brackets2
#8-32 thumb screws4
5/16 inch pan head screws4
Installing using a front-mounting kit
Before you install this platform, review the environmental guidelines to make sure that you are installing and using the
platform in the appropriate environment.
This platform includes front-mounting brackets, which you can use to attach the unit directly to the rack.
1. Align the bracket's keyhole slots with the PEM fasteners on the side of the unit.
2. Slide the bracket toward the back of the unit to lock the bracket into place.
