smartphone or tablet even after it moves out of proximity, and the configuration is transferred into the switch’s
memory once the switch is fully powered up.
Q9
. What does the BLE feature do?
A9
. The Bluetooth Low Energy feature allows remote access to the switch without having to physically connect
with a cable, so monitoring and troubleshooting and changes can be made prior to leaving the job site or after
ladders or scissor lifts have been removed. The range is approximately 100m.
Q10
. Are the BLE and NFC features safe and secure enough for my network?
A10
. NFC is considered very secure and is frequently used for contactless payments (e.g., Apple Pay). A secure
channel is established and uses encryption for sending sensitive information. However, we always recommend
users have antivirus software and passwords on their devices in case they are lost or stolen.
BLE uses Advanced Encryption Standard (AES), 128/256, SHA-1, SHA-2 (SHA-224 and SHA-256) and ECC (Elliptic
Curve Cryptography) encryption. It uses an authenticated encryption algorithm designed to provide both
authentication and confidentiality. AES was adopted by the US Government in 2002 and is used worldwide.
Q11
. Does the switch need to be mounted in a cabinet?
A11
. No, the switch is housed in its own NEMA 4X/IP66 rated enclosure and can be wall-mounted or pole
mounted (requires optional brackets). It also includes 6kV surge protection for lightning protection or other
current surges and additional fuse protection to protect from unintentional intrusions from outside power lines.
Q12
. How does the parallel power and fiber connection work?
A12
. To extend the Ethernet signals beyond the 100m Ethernet cable limitation, a combined fiber cable running
in parallel to a copper cable for the power input cable can be used, or parallel power and fiber cables can be
used. A fiber cable for the data can be run alongside a typical 16 AWG cable for the power.
Q13
. Are there any management features?
A13
. Yes, the switch IMS features include Auto Power Reset (APR) to re-boot remote devices and reduce service
dispatches. The switch has port management and PoE management, including the ability to preserve and
schedule power. Other integrated management software features include management of devices and cable
diagnostics for finding cable faults or connection issues.
Q14
. What is the app used for?
A14
. The Switch Manager Mobile App interfaces with the NFC and BLE features to allow switch configuration,
remote diagnosis and troubleshooting without having to climb a ladder or scissor lift to connect to the switch.
Q15
. What is the Digital I/O feature used for?
A15
. The digital input/digital output has four optical isolators independently configurable as either inputs or
outputs. The Digital I/O option includes an isolated 12V DC power source that can be used for alarms, event
notifications, or other customer-designated items (e.g., door open alarms, glass breakage alarms, etc.).
See the SESPM-4P-DIG Option Install Guide for more information.
Q17.
How can I tell if someone is tampering with the switch?
A17
. The switch includes tamper detection. A 3-axis linear accelerometer detects if the switch has exceeded
user-selected vibration limits, indicating someone may be tampering with the switch or if the switch mount has
somehow been compromised.
