Introducing the PRO2 •5
Chapter 1: Introducing the PRO2
Welcome to the Server TechnologySwitched PRO2
The Switched PRO2 is the latest design in Server Technology’s reliable power distribution units, providing flexibility
for future power management, cost savings, and advanced solutions for data center customers.
Key Product Features
The Switched PRO2 offers many features for the next generation of power management, including:
•PIPS® and (optionally) POPS® high-accuracy measurements for current, voltage, power, and other key
metrics. PIPS is a standard feature on all PRO2 units.
•Auto-Flip LED display gives the proper display orientation no matter how the PRO2 is mounted in the
cabinet.
•Outlet naming on all PRO2 products (for both Switched and Smart products).
•Hot-swappable network interface card (NIC) allows swapping the card in the field without causing a change
in outlet state. The NIC can easily be replaced even when power is applied.
•Support for IPv6 address names and support for SNMPv3.
•Equipped for the mobile power monitoring solution using a Bluetooth® module (for either Google Android or
Apple iOS), along with Server Technology’s ST Eye mobile application.
•Branch current measurements on both Switched and Smart PRO2 products, and notification of fuse or
breaker failure.
•Several new levels of power monitoring for high-low warning-alarm thresholds and threshold hysteresis.
•If the master unit loses power, redundant power is provided to the master via the first linked unit, ensuring
uptime.
•On-board firmware file system to allow direct GUI downloads of system files, firmware version updates, and
MIB/OID tree files without using FTP.
•Intuitive and soft-mapped naming conventions used in both the PRO2 hardware and firmware to reflect the
system hierarchy of units, cords, lines, phases, over-current protectors (OCPs), branches, outlets, outlet
groups, and sensors.

Switched PRO2 –User Guide
Introducing the PRO2 •6
What’s the PRO1?
Like the PRO2, the PRO1 (Switched and Smart) is another new PDU design from Server Technology to provide the
same type of flexibility for power management, cost savings, and advanced data center solutions that the PRO2
delivers.
What’s Unique About the PRO1?
Server Technology’s PRO1 design allows for PRO2 functionality in a CDU1 form factor.
The PRO1 uses the Sentry4-MIB and the PRO2 firmware, version 8.0.x, allowing PRO1 products to offer the latest
features and functions of the PRO2 product family.
Equipment View of the PRO1 Unit
Feature Comparison: PRO1 vs. PRO2
The PRO1 is similar to the PRO2 in hardware architecture, object mapping, user interfaces (GUI and CLI), firmware
(version 8.0.x or later), and new Sentry4-MIB, but the PRO1 does not include the following PRO2 items:
•Branch Current Monitoring feature
•TRMS Current Input Monitoring (in some cases rather than PIPS)
The following table shows a detailed benefit comparison:

Introducing the PRO2 •7
About Your User Guide
This user guide was designed for data center personnel who monitor power, control outlet actions, and administer
equipment operations in the data center network using Server Technology’s firmware, version 8.0x or later, on the
PRO2 product family.
Your guide provides installation, connection, and mounting instructions for the PRO2 product in the equipment
cabinet and illustrates the PRO2’s key features in a hardware overview.
Also provided is task-based information for working with the firmware. Step-by-step instructions are presented for
daily operational tasks on the PRO2 when using the firmware Web Interface, including GUI screen samples for
each function. If CLI is preferred, a separate chapter provides detailed command syntax and usage for every
command that can be issued on the PRO2.
PDU Power Pivot
Server Technology’s PDU Power Pivotflexible infeed provides a simplified power cord routing to the PRO2 unit
with a design that eliminates bend radius issues.
As illustrated below, the PDU Power Pivot capability can deliver a solution for several types of PDU installations
and mountings, setting the correct cord angle for overhead power, offset overhead power, concrete floor, raised
floor, and intra-rack power.

Introducing the PRO2 •8
Star Linking Technology
Server Technology’s PRO2 introduces Star Linking technology that supports the optional linking of up to three
expansion (link) units per one PRO2 master unit, allowing a single IP address for multiple cabinets.
Note: The Star Linking feature is available only with PRO2 products.
The following illustrations show multi-linking between separate units and within the cabinet:
Multi-Linked PRO2 Units Multi-Linking View in the Equipment Cabinet
Redundant Power and Communication
The Star Linking arrangement is fault tolerant, with redundant power coming from the first link unit. The
arrangement also offers significant cost reduction as the link units do not require a network card.
Another significant advantage of Star Linking technology is that if power in the master unit is lost, communication
will continue with the other link units –a major improvement over a daisy chain linking configuration.
Outlet Grouping
The multi-linking arrangement allows outlet grouping across the master and three link units.
Cable Length
The maximum cable length allowed from link unit to master unit is 21-feet.
Multi-Linking Module
In the Star Linking arrangement, the first PRO2 link unit connects via the PRO2 link port. However, the second and
third link units in the multi-linking arrangement attach to an optional T-shaped module that connects to the
Bluetooth® port on the PRO2 master unit, while still allowing full functionality for Bluetooth® mobile power
monitoring.

Switched PRO2 –User Guide
Introducing the PRO2 •9
The module and its connection are illustrated as follows:
Multi-Linking Module Connection to Bluetooth® Module Port
Getting Started
The optional Star Linking feature is sold as a separate kit purchased from Server Technology. To use the feature,
contact your sales representative to order the PRO2 Multi-Linking Module Kit, part number KIT-PRO2LINK-01M.
The kit contains:
•1 link module (labeled to show the 2nd and 3rd link unit)
•2 linking cables, (21 ft.) 6.4 m
Unit Persistence
Unit Persistence is an internal PRO2 feature that works as follows:
If a link unit is connected to a master unit, and the link unit is disconnected (powered down or accidentally
disconnected), and the master unit is restarted, the link unit will be reported as “Not Found” after the restart
because the link unit is no longer physically connected to the master.
However, the association between the master/link units is retained to allow the continuation of alerts. If the
disconnected link unit is physically re-connected to the master, the “Not Found” status will return to “Normal” status.
To intentionally remove a link unit from connection with a master unit, the link unit must be purged using the Purge
function.
Unit persistence affects all connected PRO2 master/link units whether or not they are connected in a multi-
linking configuration.

The firmware Web Interface provides an embedded file system to give quick access to system configuration files,
as well as the on-board and downloadable Sentry4-MIB and OID Tree for the PRO2, eliminating website MIB/OID
downloads.
The page also allows GUI-based file uploads (without FTP) for system, configuration, and firmware versions.
However, all PRO2 configuration/system files, MIB, and OID Tree can also be accessed via FTP/SFTP.
Intuitive and Consistent Terminology
The design of the firmware includes intuitive and soft-mapped naming conventions between the interfaces (Web
and CLI) and the PRO2 product. For example, the firmware GUI areas (cords, lines, phases, over-current
protectors, branches, outlets, sensors, etc.) match the same areas designed in the PRO2 hardware architecture.
Outlet numbers are named 1-n sequentially and the outlet name is not tied to infeeds or branches. Input cords are
also simply named 1-n sequentially (like 1-24), no longer 1-n for each phase (like XY 1-8, YZ 1-8, ZX 1-8).
Also, firmware naming formats match the exact silkscreened names on the hardware unit.
Outlet Grouping
An outlet group is named group with a collection of PRO2 outlets assigned to the group. Outlet groups can be
granted access to selected outlets by the administrative user (via the Web interface or CLI), and outlet activity by
group can be monitored on a separate Web interface page for outlet group monitoring.
Setting Thresholds
When setting threshold values, the PRO2 firmware allows expanded alerting capabilities. Threshold values can be
set by the administrative-user for multiple low/high warning/alarm levels (and threshold hysteresis), as listed below
in the following PRO2 areas.
Every item shown in the following list –for which a threshold can be set –also has a corresponding Monitoring
page for viewing the item’s current threshold values and operational status.
•Branch current (low and high).
•Cord power (low and high), cord apparent power (low and high), cord power factor (low), 3-phase out-of-
balance (high).
•Line current (low and high).
•Outlet current (low and high), outlet power (low and high), outlet power factor (low).
•Phase voltage (low and high), phase power factor (low).
•Temperature sensor (low and high).
•Humidity sensor (low and high).
•Analog-to-Digital (ADC) sensor (low and high) –if an EMCU is connected to the PRO2 unit.

PRO2 Dashboard View
The firmware Overview > System page provides a fast and high-level view of the overall condition of the PRO2
unit. The sub-system status view shows the current operational state of individual PRO2 (units, cords, lines, etc.).
The color-coded status icon for each area is hot-linked to the corresponding monitoring page to show the operating
details behind the status, for example:
