1. Introduction
The SurgeX Defender Series+ is an AC power distribution unit with power conditioning, control, and
monitoring, with independently IP switchable AC receptacles and current monitoring for the inlet. Design for
mounting on the rack. The internal web server provides configuration, output control, monitoring, and retrieval
of data logs. Multiple security and communication interface options are supported.
Defender Series+ incorporates SurgeX Multistage surge suppression and EMI/RFI filtering technology. This
protection safeguards the AC outlets.
The extensive programming capabilities of the Defender Series+ provides advanced sequencing and
scheduling operations. Triggers can be programmed to activate on an “if X then do Y, then do Z when no longer
X” basis. Trigger sources include various AC power measurements, scheduling, and AutoPing. Actions include
turning receptacles on and off, cycling a receptacle, executing previously defined sequences, and putting a unit
into shutdown. For example, an action can be created to power cycle a network appliance if it fails to respond to
a series of pings.

4.4.4 Triggers Setup
The Triggers Setup page allows for the modification of triggers. Triggers define event logging
parameters and allow configuration to automatically control and protect connected
equipment. Triggers are categorized into three types: AutoPing, Threshold with Samples, and
Schedule, but all have the same possible actions. Actions can either be on the onset
(Trigger/Alarm Actions) or offset (Clear Actions) of a trigger. All Triggers are logged along with
the associated actions.
Action Types
Item
Description
None
Do not take any action; only log the event. This is useful as a Clear Action when an
action should persist, or for both Alarm and Clear actions when just logging the event is
desired.
Power On
Power on a specific outlet if the outlet configuration allows it.
Power Off
Power off a specific outlet if the outlet configuration allows it.
Reboot
Reboot a specific outlet if the outlet configuration allows it. If an outlet is already off
when this command is issued, the outlet will simply turn on after the outlet specific
reboot delay time.
Test User
A button to send an authentication request using the given settings for the user and password
above. NOTE: Settings should be saved using the "Save Settings" button at the bottom of the
page before testing a configuration change.
Trigger Types
Item
Description
Threshold with
Samples
Uses measurements over an allotted time to take an action. This trigger type is
configurable to act very quickly or very slowly depending on environmental/system needs.
AutoPing
Issues a ping function on a periodic basis to determine if an IP asset is accessible.
Schedule
Uses the device time to issue a one time or periodic command. We suggest ensuring the
NTP server is updating correctly to use the schedule trigger.

User Manual
4.4.5 Users Setup
The Users Setup page allows for the
creation, deletion, and editing of user
accounts. Each user will have a unique
name, username, authentication mode, and
may be assigned access to specific features.
LDAP and Internal authentication modes are
supported.
The following privileges may be assigned or
revoked as necessary:
• Trigger Config
• Device Control
• Network Settings
• Software Update
• User Administration
4.4.6 Sequences Setup
The Sequences Setup page allows for the
creation and modification of sequences. A
sequence is a set of actions to be
taken in a specific order and with a
specified delay time between each
step. Using sequences avoids manually
performing each action or turning
each outlet on or off individually.
A sequence, as defined for this product, is purely a one-way sequence. That is, you do not use the
same sequence to turn outlets on as you use to turn the same outlets off in reverse order. One
sequence must be created for the turn-on function and then a second sequence must be created for
the turn-off function.
To create a new sequence, press the “Add Sequence” button. The new sequence must be given
a unique name. This name should clearly indicate what the sequence will do, such as “All On”, “All
Off”, or “Stage Equipment On”.
To run a sequence to test it, press “Run Sequence”. To edit an existing sequence, press the pencil icon.
To delete a sequence, press the minus “-“ icon.

User Manual
After a sequence has been saved, it will be available at the Sequences page and when creating or
editing a trigger when run sequence is selected as an action.
*Time delay is specified from the previous sequence item, not from the initial starting point. For
example, creating a sequence with “Step 1, 1 second, Outlet 1, On” and “Step 2, 1 second, Outlet
2, On” will turn on Outlet 1 after 1 second, and Outlet 2 on 1 second after Outlet 1 has turned on.
This sequence will not turn on both Outlets 1 and 2 at the same time.
Sequence Actions:
• None (useful for additional time delays)
• State Change
o On, Off, or Reboot

5. Security
Defender Series+ has been designed with security as a priority. All ports and features may be changed or disabled.
5.1 Authentication
Defender Series+ supports basic and secure authentication for users and network connections.
5.1.1 802.1X
802.1X network authentication may be enabled for networks requiring supplicant authentication.
5.1.2 SSO (Single Sign-On)
Defender Series+ users may be configured to use either Internal or SSO (Single Sign-On) authentication.
Internal authentication uses basic usernames and passwords assigned by the administrator on a per-unit
basis. SSO authentication uses LDAP (Lightweight Directory Access Protocol) to authorize users and
determine their level of privileges using Microsoft® Active Directory. While it is possible to use LDAP to
authorize users without SSL encryption, we suggest only configuring the connection to the authentication
server using SSL encryption to plain text network traffic.
5.2 Interfaces
5.2.1 Network Interface
• Web Server: It is possible to enable and disable the internal web server, change the security from none
(HTTP) to TLS 1.2 (HTTPS), as well as change its port. These settings also apply to the REST API.
• S
NMP: SQUID supports SNMP V3 for secure communications with the ability to enable and disable.
