Overview

Raritan's Smart Rack Controller (SRC) provides a rack management solution

that combines the capabilities of environmental monitoring, asset

management, image surveillance, event notifications and support for Schroff

®

heat exchangers.

In addition, you can even control the access to cabinets with Raritan's door

handles (or SmartLock kit).

Important: Asset management feature and door handles (or SmartLock kit)

are mutually exclusive. You cannot have both devices connected

simultaneously.

Environmental monitoring and/or system control:

At least one Raritan DX or DX2 environmental sensor package is required

for this feature.

After connecting Raritan environmental sensor package(s) to SRC, you can

remotely monitor surrounding conditions in the data center, such as

temperature or humidity, or control a system if actuators are connected.

Note: SRC does NOT support these other Raritan environmental sensor

packages: DPX, DPX2, DPX3 (except for the DPX3-ENVHUB4 sensor hub).

Cabinet access control:

Raritan's door handles or SmartLock kit is required, which is model

dependent.

▪ You only need two door handles when your SRC model has onboard

door handle ports, such as SRC-0102.

If you want to increase the number of door handles from two to four,

you can purchase a SmartLock kit and then connect it to this SRC's

SENSOR port.

▪ You must purchase the SmartLock kit if your model does NOT have

onboard door handle ports, such as SRC-0100.

Raritan's SmartLock kit contains one DX2-DH2C2 and a pair of door

handles.

Chapter 1

Introduction

Chapter 1: Introduction

2

After properly connecting and configuring door handles or the SmartLock

kit, you can control the access to the selected cabinet via SRC.

Asset management:

You can remotely track the location of IT equipment after tagging IT

devices electronically. This feature is especially useful when there are a

number of IT devices to administer.

The following are required for setting up the asset management system:

▪ Raritan asset tags: You tag an IT device by sticking an electronic asset

tag on it.

▪ Raritan asset management strips (asset strips): Each asset strip

transmits the tag and position information to SRC.

▪ An SRC device: You can remotely locate each tagged IT device through

SRC.

Image surveillance:

With a Logitech

®

webcam connected, a simple camera and video

surveillance system is established so that you can remotely view real-time

snapshots or videos of the data center.

Event notifications:

Event rules and actions that are triggered when an event occurs are

supported by SRC.

Email messages, log events, syslog messages, webcam snapshots, SNMP

traps and SMS messages can be triggered when the events you define

occur.

In addition, images captured by the webcam can be emailed to users in

response to a specific event.

Integration with Schroff

®

LHX/SHX heat exchangers:

SRC can integrate with a Schroff

®

LHX-20, LHX-40 and SHX-30 heat

exchanger, which draws warm air into the air/water heat exchanger to cool

the air. This integration provides a solution for remotely monitoring the

heat exchanger.

Product Models

There are two SRC models:

• SRC-0100

• SRC-0102

They are functionally identical except that SRC-0100 does NOT have onboard

door handle ports and contact closure terminals while the other model has

them.

Note: For a list of available asset management strips and tags, visit the Raritan

website's Product Selector page (http://www.findmypdu.com/).

SRC-0100

SRC-0100 has the following ports and components:

To control access to a cabinet via this model, you must purchase Raritan's

SmartLock kit.

DUAL INLETS:

Dual inlets can supply redundant power to this model.

STANDARD CONNECTION PORTS:

▪ CONSOLE/MODEM port x 1 (blue)

▪ Sensor port x 1 (yellow)

▪ USB-A port x 2

▪ USB-B port x 1

▪ Feature port x 1 (red)

▪ Ethernet port x 2 (green and white)

For details, see Connection Ports (on page 67).

Note: Expansion port is reserved for future use so it does NOT function

now.

FRONT PANEL LCD and CONTROL BUTTONS:

Front panel LCD and buttons let users view real-time device information

and/or alerts without logging in to the SRC software. See Dot-Matrix LCD

Display (on page 70).

SRC-0102

SRC-0102 has the following ports and components:

DUAL INLETS:

Dual inlets can supply redundant power to this model.

ONBOARD DOOR HANDLE PORTS and CONTACT CLOSURE

TERMINALS:

These ports support the cabinet access control feature and contact closure

sensors. See Onboard Door Handle Ports and Contact Closure Terminals

(on page 69).

STANDARD CONNECTION PORTS:

▪ CONSOLE/MODEM port x 1 (blue)

▪ Sensor port x 1 (yellow)

▪ USB-A port x 2

APIPA and Link-Local Addressing

SRC supports Automatic Private Internet Protocol Addressing (APIPA).

With APIPA, your SRC automatically configures a link-local IP address and a

link-local host name when it cannot obtain a valid IP address from any DHCP

server in the TCP/IP network.

Only IT devices connected to the same subnet can access the SRC using the

link-local address/host name. Those in a different subnet cannot access it.

Exception: SRC in the Port Forwarding mode does not support APIPA. See

Setting the Cascading Mode (on page 177).

Once the SRC can get a DHCP-assigned IP address, it stops using APIPA and the

link-local address is replaced by the DHCP-assigned address.

Scenarios where APIPA applies:

• DHCP is enabled on the SRC, but no IP address is assigned to the SRC.

This may be caused by the absence or malfunction of DHCP servers in the

network.

Note: Configuration by connecting the SRC to a computer using a network

cable is an application of this scenario. See Connecting the SRC to a

Computer (on page 21).

• The SRC previously obtained an IP address from the DHCP server, but the

lease of this IP address has expired, and the lease cannot be renewed, or

no new IP address is available.

Link-local addressing:

• IPv4 address:

Factory default is to enable IPv4 only. The link-local IPv4 address is
