The CMM4 provides:
• Sync over P ower over Ethernet and integrated surge suppression on the controller board
for up to 8 AP s or BHs. Both a custom 30 VDC power scheme and a custom 56 VDC power
scheme are available. Neither is the same as the later IEEE Standard 802.3af, and neither
is compatible with it.
• Managed switching using a hardened EtherWAN switch. The CMM4 ships with a 14 - port
EtherWAN switch and is also available without a switch.
• A weather - tight enclosure with either 4 or 7 glands/ports for Ethernet and power cables.
• Surge suppression on the controller board for the incoming 30V DC and 56V DC power
lines
and GPS coax cable.
