Important! Only attach or remove a Neutrik powerCON connector while it is connected to the mains in
case of an emergency, as doing so may cause arcing at the terminals that will damage the connectors.
Backup Power Supply
The device has two built-in PSUs. If both PSUs are connected to the mains, the primary PSU will supply the device while
the backup PSU stays in standby mode. Should the primary PSU fail, the backup PSU will immediately start to power
the device without an interruption.
Power Outlets
Warning! The current load of each of the AC mains power outlets of the XES-8G must not exceed 19.8
amperes.
• A p
ower cable that meets the requirements specified in the safety instructions section of this manual must be used
to connect the XES-8G to AC mains power and to connect other devices to the power outlets.
• A light
-grey Neutrik powerCON NAC3FCB cable-mount connector must be used to draw AC mains power from the
XES-8G
’s power outlet
.
• No matter what the AC
mains power voltage is, the current drawn by all the devices that draw AC mains power from
one of the power outlets of an XES-8G must not exceed a total of 19.8 amperes. That is 19.8 amperes for the primary
PSU mains loop through output and another 19.8 amperes that may be drawn from the backup PSU mains loop
through output.
Network Connectors and Cables
All network connectors are Neutrik etherCON Cat 5e RJ45 connectors. These connectors may be used with a standard
RJ45 plug. For a better fixation, you may use a cable with a Neutrik etherCON plug. For Gigabit Ethernet (1000BASE-T)
operation, Cat 5e (or better) RJ45 cables are required. 100 Mbit/s (100BASE-TX) requires at least Cat 5 cables. For 10
Mbit/s (10BASE-T) Cat 3 cables are sufficient. In any case, the maximum allowable cable length is 100 m (328 feet).
Status LEDs
The XES-8G has three status LEDs for each of the network ports plus a status LED for either of the power supplies. The
LED for the primary PSU (2) and the LED for the backup PSU indicate whether the respective PSU is powered from the
mains and functioning.
The Link LEDs (6) are lit when the respective network port has established a network connection. The 100 Mbit/s
Activity LEDs (5) indicate whether the corresponding port is working at 100 Mbit/s. When a 100 Mbit/s connection has
been established, these LEDs also show the activity of the respective ports. The more activity is present at a port, the
more frequently the corresponding LED will turn off for an instant. The 1000 Mbit/s Activity LEDs (4) light up when a
Gigabit Ethernet connection has been established and display the port activity in the case of a Gigabit Ethernet link.
Differentiated Services (DiffServ) Based QoS
The switch implements Differentiated Services (DiffServ) with four queues with the following queue assignments as
required for optimal quality of service (QoS) with the Dante protocol:
