This chapter describes the Sentriant chassis architecture, instructions for mounting the chassis in a
standard four-post (front-mount) and a two-post (mid-mount) system racks and cabling.
Sentriant Chassis Architecture
This section describes the physical description of the chassis, the front panel, and rear panel features.
Physical Description
The Sentriant is housed in a 2-RU chassis (18-inches (45.72-cm) length, 17.25-inches (43.81-cm) wide, and
3.5-inches (8.89-cm) high. The chassis is designed for 19-inch (48.26-cm) width racks.
Front Panel Features
Figure 1 shows the front panel.
The front panel of the Sentriant has the following:
●Serial Port - Connects a DB-9 serial connector to a terminal. This port is used to perform initial
configuration and maintenance to the Sentriant. The serial port requires a standard DB-9 connector
(Null Modem).
●Management Port - Connects an Ethernet cable to the I/O port of a switch. This port is used to
manage the Sentriant. Detection and mitigation of threats are not performed on the management
port. When you configure the IP Address for a Sentriant, this address gets assigned as the
management IP Address. Endpoints running Sentriant Console Manager will use this address to
connect to the Sentriant.
●Four Gigabit Ethernet Detection/Mitigation Ports - Connect Ethernet cables to the I/O ports of a
switch. These ports are used to detect and mitigate network traffic threats on configured segments of
a switch.
●Reset Switch - Used to reboot the Sentriant.
●LEDs - Used to determine the status of each Ethernet port.
WARNING!
