About the Security Appliance Chapter 1
Power Supply
The Stratix 5950 security appliance comes with redundant external power
connector. The connector supports 12 - 48V DC. The connectors are Molex
5.00 mm Pitch Eurostyle Horizontal Plug, with Retention Screws.
The power supply does not support reverse polarity, but does have reverse
polarity protection. If you reverse + & - connections, the system does not
power on and there is no damage.
The + terminal always has to be greater than the - terminal for the system to
operate. The difference is in the system grounding scheme that is used.
The Stratix 5950 security appliance supports three basic schemes:
• Isolated DC in, neither + nor - terminal is tied to chassis GND
• Positive DC in, negative (-) terminal is tied to chassis GND
• Negative DC in, positive (+) terminal is tied to chassis GND

Memory and Storage
The Stratix 5950 security appliance has 8 GB of DRAM. It also has two
storage devices, a 50 GB SSD and a 15 GB update device. All memory
components are factory default and not upgradeable by the end user.
SD Card
The Stratix 5950 security appliance has an SD card slot as shown in
Figure 3 on page 14
. The SD card lets you have easy access to updates, copy
logs, and crash-dumps. You can copy anything from the ASA file-system
(disk0) to the SD card. One, blank SD card (1 GB) is shipped with the
appliance.
USB Ports
The Stratix 5950 security appliance has two externally accessible Type-A USB
(4-pin) connectors. Each USB port supports output of 5 volts power and up to
a maximum of 500 mA.
TIP To confirm uninterrupted operation, the redundant power connections must
be connected to independently separated power sources.
