Record MAC addresses
Control MAC addresses should be supplied with your unit and are printed
on each module control port. These should be recorded s they will be
needed for configuration.
Control port MAC address
Low live 00:20:4A:
Low backup 00:20:4A:
High Live 00:20:4A:
High backup 00:20:4A:
Network connections
Connect low side Control and Data network ports to the dirty network(s)
and High side network ports to the clean network(s) prior to power
connection.
Connect power
Connect power and turn switch to on position. Please note: while it is
usually safe to connect data and control connections with the unit power
applied, precautions should be taken when connections have come from
a different electrical environment or over long cable runs, where
common-mode voltage differences or electro-static potentials may arise.
Ensure that all rack ground connections are secure before powering on
the unit and connecting data cables. Power-cycling may be required to
re-initialise non-High-Availability types of unit.
Network requirements
High side data connections must be on low-contention Gigabit Ethernet
networks. Any network delays on the high side network will cause
AROW's buffers to fill. If delays on the high side network are greater than
on the low side, the buffers will overrun, causing loss of data.
Buffer state ( and thus network performance) can be monitored by
reading status (see section 8 CONTROL AND STATUS)
