Other recommended type of substation clock is LANTIME M400 manufactured by Meinberg.
It supports GPS / GLONASS clock and synchronization of IEEE 1588-2008 (PTPv2) compatible
clients via IEEE C37.238-2011 Power Profile, two step clock. Refer to
additional information.

Layout
The communication devices are usually mounted inside the low voltage compartment of the
panel. Therefore, the panels are ready for connection. The main benefits of this solution are:
–
Cubicles are ready for connection
–
Saving space in substation building
–
Shorter communication links
–
Cheaper solution
Protection relays are connected to the Ethernet network in compliance with the Network
Overview Diagrams. It is recommended to wire communication link from Ethernet switch to
protection relays and keep minimal allowed bend radius especially for fiber optic patch cords.
