### Q: does the switch comply to CE regulations (EMC)?
|
|
|
|
|
|
A: It is. The company Seven Solutions has performed extensive EMC tests
|
|
|
on the switch.
|
|
|
on the
|
|
|
switch.

### Q: Is WR Switch inter-operable with standard PTP (IEEE1588-2008) gear ?
|
|
|
|
|
|
A: Yes, it is and it has been tested for inter-operability on ISCPS
|
|
|
PlugFest, but
|
|
|
|
|
|
- currently, WR devices (Switch/nodes) do not support standard-PTP
|
|
|
slave mode. This means that a standard PTP device can "slave" to WR
|
|
|
device (being master) but a WR device cannot slave to standard PTP
|
|
|
device (WR device cannot be standard PTP-slave)
|
|
|
- it is important to remember that we use a very specific PTP
|
|
|
configuration (2-step, delay request-response mechanism, multicast,
|
|
|
Layet 2) which is not the most popular configuration and it is not
|
|
|
the default setting for standard
|
|
|
standard-PTP switches (which use IP instead of Layer 2). So it is
|
|
|
not just plug\&play, it's more like
|
|
|
1\. buy PTP switch which supports fully the standard
|
|
|
2\. configure it properly (change from IP to Layer 2)
|
|
|
3\. plug & play
