The CU2008 switch ($150) offers 8 RJ 45 Ethernet ports, while the CU2016 switch ($282) features 16 ports. These streamlined Ethernet Switches replace the vendor’s previous ES series of switches. The CU series switches retain the same form factor with identically arranged RJ 45 sockets and power connections. The status LEDs, are easier to read because they are located directly on the RJ 45 sockets. The new devices no longer have a configuration DIP switch (for which there is generally no need), eliminating the risk of configuration errors during installation and use.
