7. The unit will then reboot. The process is complete when the LEDs are back to their “normal” status.
NOTE: If the unit gets disconnected from the AC power or something else occurs during the firmware update that results in the
unit not being rebooted, leave the power on. The unit should boot back to the normal mode.
NOTE: Do NOT push the safe mode button on the back of the unit.
If the unit does not boot back to normal mode or reamins with the LEDs circling in a counter-clockwise rotation after 30 minutes,
the unit is most likely stuck in safe mode.
If this is the case, DO NOT CONTINUE TO PRESS THE SAFE MODE BUTTON ON THE BACK OF THE UNIT. Instead, perform the
following steps:
Firmware Update Mode Using LinuxIPSet
NOTE: We recommend tha you use the Web interface when upgrading the firmware on the units. If you are not able to access
the Web interface, then use the LinuxIPSet.
To set the unit back to normal mode:
1. Power OFF your device.
2. Connect the ServSensor V4E via crossover cable directly to your computer’s network interface card.
3. Reconfigure your network interface card’s TCP/IP settings (IP Address: 192.168.0.2, subnet address: 255.255.255.0, default
gateway and DNS: leave both blank).
4. Make sure that firewall programs are temporarily turned OFF or make an exception for InuxIPSET5.8.1.exe.

Creating a Backup Configuration File
Keep in mind that after you set up your ServSensor V4E unit and have all the settings and alerts completed, you can create a
backup configuration file. This file will contain the configuration of the unit’s settings and also the sensor settings and notification
alerts.
These backup configuration files can be loaded on other units as long as they are the same basic type. For example, you can load
a backup config file from a ServSensor V4E onto a ServSensor V4ES unit. You can also use the utility to push out the same
configuration file to multiple units on your network simultaneously.
Figure 3-13.
To create your backup config file, you first need to log in to the unit as an Administrator. Then, navigate to the
Settings page > System Administrator >System Maintenance and click on the “Backup” button as shown in the screen shot
above.
You will then browse to where you would like to store the backup file on the PC, choose the Save button, then click on the OK
button.
You can restore this or another backup file using the Restore All Settings From Backup File.

Figure 3-24. Active services.
You can also close or change the ports used to access the unit’s Web interface, disable HTTP, and enable HTTPS only.
The “s” at the conclusion of HTTPS stands for secure. The SSL/TLS connection type is used primarily for high-value sites or
“pages,” to make it more likely to be unreadable to someone at the end points.
The traffic between client and the ServSensor V4E is not cached along the various units as it moves across the Internet, so it can’t
be accessed by someone after the connection is terminated.

Chapter 3: Installation
Use the SNMPv3 SSL (Secure Sockets Layer), which is the standard security technology for establishing the encrypted link betwen
the ServSensor and the Web browser. The link ensures that all data passed between the ServSensor and the browser remains
private and integral.
SNMPv3 provides important security features:
• Confidentiality—Encrypts packets to prevent snooping by an unauthorized source.
• Integrity—Message integrity to ensure that a packet has not been tampered with in transmit.
• Authentication—To verify that the message is from a valid source.

3.5.4 Active Security
Figure 3-27. Network Access Control screen.
In the active security section, you can enable users who are logged into the unit’s Web interface to “Acknowledge” alarms, which
is normally reserved only for the Administrator.
When the unit boots up, it will announce the IP address that it has been configured with. As an added security feature, this
announcement can be disabled so that the IP address remains unknown.

3.5.5 The NAC or Network Access Control Security Feature
The NAC or Network Access Control feature enables you to restrict access to the Web interface for only certain IP addresses, or
deny access to the Web interface for only certain IP addresses.

3.6 Setting Up a Sensor
This section describes the basic setup of a sensor, using a Black Box temperature sensor as an example. If you require information
on specific functions of a particular sensor, then download the manual for that sensor from our Web site, www.blackbox.com.
1. Plug the sensor into one of the RJ-45 “intelligent sensor ports” on the ServSensor’s rear panel. In this example, we will use
Port 1. See Figure 3-29.
Figure 3-29. Intelligent sensor Port 1.

2. Point your browser to the ServSensor’s IP address (the default is 192.168.0.100). Log in as the administrator using your
administrator password (the default is “public”). You will then be taken to the summary page shown in Figure 3-30.
Figure 3-30. Summary page.
The temperature sensor should be listed, along with its current reading and status. If this is not shown, go to Chapter 9.
This summary page enables you to quickly see which sensors are connected and their status, view the system log, and also view
footage from any connected cameras. Next are some of the tools the Web-based interface provides for getting feedback from
the sensors.

3. Click on the temperature sensor’s name (indicated in Figure 3-29). This will bring you to Figure 3-31, the Sensors page.
Figure 3-31. Sensors page.
NOTE: Another way to access this page is to click on the “Sensors” tab at the top of the page.
3.6.1 Notification Thresholds
From this page, you can carry out various operations as indicated above. You can also view the current status (normal, low critical,
high critical, etc). In Figure 3-30, the sensor indicates a temperature of 29° C and a status of Normal. If you click on the blue
marker arrow next to the “Set the required threshold” label (shown in Figure 3-31), you can drag this marker to re-configure the
thresholds. After dragging the marker, click “Save.” In Figure 3-31, you can see that this marker has been moved to make a new
threshold, and the sensor status has changed along with it.
