Physical and Environmental
Feature
Detailed Description
Internal Power Supply
AC Input: 100 – 240 VAC, 50-60 Hz
Optional Redundant
Power Supply
Provides one connector in rear panel to install optional external RPS to enhance the
reliability. When internal power is failed, the optional external RPS will take over all the
power immediately and automatically.
Security Lock
Provides a Kensington-compatible security lock, at the rear of the switch, to be able to
connect to a secure immovable device. Insert the lock into the notch and turn the key to
secure the lock. The lock-and-cable apparatus should be purchased separately.
Power Consumption
56.2 Watts (Max.)
Operating Temperature
0°C to 50°C
Storage Temperature
-40°C to 70°C
