allows SNMP management platforms to obtain unique names for units where specified.
The system name has no effect on network communications, and the unit will function
correctly with or without a value.
System Location
You can specify the system location here.
You can retrieve the system location name by querying the ‘sysLocation’ node via
SNMP. This allows SNMP management platforms to obtain location names for units
where specified.
- 29 -
SmartZone Gateway EP042 User Manual
The system location name has no effect on network communications, and the unit will
function correctly with or without a value.
Contact Name
You can retrieve the unit support contact name by querying the ‘sysContact’ node via
SNMP. The contact name has no effect on network communications and the unit will
function correctly with or without a value.
IP Address
You can enter a standard IP address here. The address is entered in decimal format (for
example: 192.168.0.44 or 22.10.45.33).
The address entered here will be the address by which the Gateway unit is accessed
and managed.
Subnet Mask
The subnet mask is used to determine what part of the IP address is the network portion
and what part is the host portion.
It is often 255.255.0.0 or 255.255.255.0. The correct setting is essential for correct operation.
The subnet mask is entered in decimal format (for example: 255.255.255.0 or
255.255.0.0).
Gateway
The Gateway setting specifies the IP address of the machine/router that the Gateway
unit uses to communicate with different networks.
The Gateway address is entered in decimal format (for example: 192.168.0.1 or
11.2.24.103).
Most networks will have a Gateway. Correct setting is important for correct network communications.
Note: Once you enter the IP Configuration options and click Save, the changes take
effect. If incorrect entries are made, this may result in loss of communication. If this happens, reset the Gateway unit's network configuration. Details of how to do this can be

Status
The Input Sensors status page presents an overview of the input ports. This page displays the input channel number, name, type of input sensor, status, current readings, and
thresholds.
Status Indicators
Three status indicators are displayed next to the input channels to allow quick determination of normal, warning, and critical alarm statuses:
Channel reading currently within threshold limits.
Upper or lower Warning limit reached/exceeded.
Upper or lower Critical limit reached/exceeded.
Input Sensors – Defaults
The Input Sensor Defaults menu allows configuration parameters for input sensors of
specific types to be defined and applied to all inputs of that type.
The types of input sensors are:
- 43 -
SmartZone Gateway EP042 User Manual
l Temperature
l Humidity*
l Analog (Voltage)
l Open/Close Contacts (digital inputs)
*Note: Rack Energy Kits do not support humidity sensors.
The configurable defaults are described below.
Calibration Offset
The value entered here alters the actual reading of a sensor by the amount specified.
For example, if a Calibration offset of 6 was used and a sensor's true reading was 36,
the indicated reading used for display and alarm purposes would be 42. This works the
same way for both temperature and humidity sensors.
Hysteresis Value
The hysteresis default value to be applied to sensors is specified here. The value specified is an offset from a sensor's threshold values.
For example, a hysteresis value of 5 would mean that, in the case of an Upper Control
Limits alarm, the alarm value would have to reduce to 5 below the threshold value before
another alarm is issued.
- 44 -
SmartZone Gateway EP042 User Manual
Please see Appendix B: Hysteresis Demystified for detailed information.
Limits and Traps
You can set default values for sensor alarm thresholds here. You also can set the default
settings for alarm threshold traps here.
The following thresholds can be set:
l Upper Control Limit
l Upper Warning Limit
l Lower Control Limit
l Lower Warning Limit
You can apply default trap settings for all of these thresholds. With the trap box deselected, no SNMP alarm traps will be generated, even when an alarm condition exists for
that threshold.
Repeat Timer
The repeat timer causes alarm traps to be reissued after a specified amount of time if the
alarm condition persists.
Setting the repeat timer to 0 will disable the repeat traps.
The defaults that can be set for Open/Close contacts differ from the Temperature and
Humidity settings.

SmartZone Gateway EP042 User Manual
Normal State
Normal state specifies the condition in which a contact is considered to be in a Normal,
Non-alarmed state.
Devices such as smoke alarms and air conditioning units often have normally open contacts. To receive alarm indications from these types of units would cause alarms to be
issued when a monitored contact closes.
Setting normally closed in the case of a rack or cabinet door would cause an alarm condition when the door was opened.
Trigger Type
The trigger type defaults for Open/Close sensors are specified here.
The three available options for trigger types are:
Level
Level triggering is the default mode. When an input physically transitions from a Normal
to Non-Normal state, an alarm is triggered. However, the alarm persists only while the
input remains in a Non-Normal state. When the input returns to a normal state, the alarm
is cleared.
Normal to Non-Normal (Positive Edge)
This type of triggering may be used in situations where a momentary type input (for
example,: a shock sensor or PIR) is used. Since these types of inputs are momentary,
any alarm condition that occurs will persist until manually cleared.
Positive Edge triggering is used when an alarm is required to persist after an input
changes from the Normal state to the Non-Normal state.
Non-Normal to Normal (Negative Edge)
This type of triggering may be used in situations where a momentary type input (for
example, a shock sensor or PIR) is used. Since these types of inputs are momentary,
any alarm condition that occurs will persist until manually cleared.
Negative Edge triggering is used when an alarm is required to persist after an input
changes from the Non-Normal to the Normal state.

The submenus contain all the options in the Defaults menu, plus two additional options:
Name
Sensor channels can be assigned names for ease of identification (for example, “Server
Room Sensor” or “UPS Battery Fail”).
Type
The type of connected sensor is specified here. The sensor channels can be set to auto
detect, temperature, humidity, contact, or disabled.
Note: Occasionally, clear traps will be sent to the NMS trap receivers while a sensor is
being connected to a device. This is considered normal behavior, because some voltage

Control Method
The Control Method parameter specifies which control methods are available to control
the outlets on PDUs attached to the unit.
HTTP + SNMP
The Web Management Interface and SNMP can be used to command PDU outlets.
HTTP Only
This option allows only the Web Management Interface to command PDU outlets. This
effectively disables SNMP PDU outlet control.
SNMP Only
This option allows only SNMP to command PDU outlets.
This effectively disables the Web Management Interface PDU outlet control.
RS232 Only
This option allows PDU control commands to be issued directly to a unit via the onboard
RS232 port. This option disables the Web Management Interface and SNMP control.
Cycle Up/Down Delay
This parameter specifies the interval in seconds between switching on and switching off
outlets when an entire PDU is cycled (all outlets commanded on or off).
Repeat Timer (on Comms Failure)
This parameter specifies the interval in seconds between when an initial PDU comms
failure trap is produced and a repeat trap is issued.
Reboot Delay
This parameter specifies how long (in seconds) an outlet remains off after a reboot
before switching back on.
Abort Cycle Delay
This parameter specifies how many seconds must elapse before a commanded cycle
begins on a PDU. This delay gives the user time to reverse the decision to cycle a PDU
before any outlet states are changed.

Per Outlet Monitor and Control
This option enables PDU-level monitoring and monitoring of each individual PDU outlet,
plus outlet control.
Number of Outlets
This parameter specifies the number of controllable outlets present on a PDU. This is
required when the Control Only or Monitor and Control options have been selected.
For example, if you have a PDU consisting of 24 Outlets, one of which is a permanent
live (non-switching) outlet, 23 outlets would be specified.
Warning: Failure to specify the correct number of outlets can lead to the incorrect outlet
being switched on or off.
During unit setup and deployment, you should select the Control Only or Monitor and
Control options before critical loads are connected to outlets.
Cycle Password
This field specifies the password required to set a power cycle of outlets on a controllable strip. This password is used when switching outlets using SNMP, not when
switching via the web interface.
Power on Mode
In the event that power to the PDU is lost, this parameter specifies how the outlets will be
switched back on once power is restored.
RMS Volts
Repeat Timer
In the event of a communications failure with a connected PDU, this entry specifies how

LDAP
Note: LDAP information does not apply to the Gateway EP042 when used with a Rack
Energy Kit.
SmartZone Gateway LDAP Overview
The SmartZone Gateway unit implements a Lightweight Directory Access Protocol
(LDAP) client. This allows the Gateway unit to authenticate user logins to the Web Management Interface using an LDAP Directory.
If LDAP is used for authentication, it is first consulted when a user attempts a login. If the
user is not found or access is denied by LDAP, then the credentials are checked against
the Gateway unit internal user list.
- 56 -
SmartZone Gateway EP042 User Manual
Note: Anonymous LDAP lookups are not supported.
Note: Configuration of LDAP is an advanced topic and requires existing knowledge of
LDAP function and setup.
SmartZone Gateway LDAP Structure
For a Gateway unit to successfully authenticate a user for a Web Management Interface
login, it needs to be pointed to a specific structure within a directory. You can point a unit
to this structure within a directory by specifying the Unit Base DN on the Network Setup
– LDAP page.
You will need to create the following Organizational Units:
l Gateway (this can be named anything)
l Gateway Administrators
l Gateway Controllers
l Gateway Viewers
Note: Groups are found in the Active Directory schema. However, any implementation
which provides a group with a Members attribute may function.
The following figure depicts the Gateway LDAP authentication structure:
- 57 -
SmartZone Gateway EP042 User Manual
Once the required LDAP structure has been created, the Distinguished Name (DN) of
users should be added to either:
l Gateway AdminUsers
l Gateway ControlUsers
l Gateway ViewUsers
Group Membership and Access Level
Membership in these groups grants the following permissions on Gateway units:
Gateway AdminUsers
Users placed into this group will have Admin privileges on Gateway units.
- 58 -
SmartZone Gateway EP042 User Manual
Gateway ControlUsers
Users placed into this group will have Controller privileges on Gateway units.
Gateway ViewUsers
Users placed into this group will have View privileges on Gateway units.
SmartZone Gateway Unit Configuration
For LDAP authentication to function, you need to provide certain configuration values for
each Gateway unit.
To enter the configuration values, perform the following steps.
1. If one LDAP server is to be used, select Enabled – Primary.
2. Enter a descriptive name (for example, AD_Server_1) into the Display Name (DN)
field.
3. Enter the complete DN of the top level OU.
4. Enter the DN of where users that are members of Gateway access groups can be
found in the Directory. These DNs can be entered into User Base DN 1 and User
Base DN 2.

Appendix B: Hysteresis Demystified
When a temperature or humidity limit is reached and the relevant limit has its OFF to ON
Trap enabled, an alarm trap is issued by the SmartZone Gateway unit.
With a zero hysteresis setting, the traps will continue to be generated each time the limit
is reached.
This may be undesirable in a situation where the temperature or humidity level measure
has reduced by only a small amount before rising again and triggering further traps.
The hysteresis function is provided to prevent further alarm traps from being generated
until the measured value has fallen to a satisfactory level.
As shown in image above, the humidity first rises past its upper warning threshold, which
generates an alarm trap.
The humidity then reduces slightly but does not reduce to the hysteresis level, which is
1.5% relative humidity lower than the alarm setting (1.5% relative humidity lower as an
absolute measured value, rather than 1.5% of currently measured value).
Humidity then increases and decreases again. However, on the second decrease of
humidity the level drops below the hysteresis level. The Humidity falling below the hysteresis level re-enables alarm traps for the next alarm event. An upper limit of 25 and a
hysteresis threshold of 1.5 yield a threshold limit of 23.5.
The humidity level again begins to rise and again exceeds the upper limit, however this
time an alarm trap is generated again.
- 68 -
SmartZone Gateway EP042 User Manual
The Hysteresis feature acts on the following Temperature and Humidity thresholds:
l Upper Control Limit (UCL)
l Lower Control Limit (LCL)
l Upper Warning Limit (UWL)
l Lower Warning Limit (LWL)
The inverse of the above description is true when applied to Temperature and Humidity
lower control and warning limits.
You can configure the hysteresis threshold by using the menu options.
