Network Resilience
Each chassis can be configured with either one, or
two power supply modules (AC) to provide
resilience against a power supply failure.The
management module monitors the state of each
power supply, and that of the cooling fans, and will
generate an alarm should any parameter fall
outside of normal operating conditions. With
redundant power supplies installed, a power
supply can be remove or re-inserted into the
chassis without interruption to the media blade
traffic.
The management module can also be hot
removed and inserted without disruption to the
media blade traffic.
A media blade can be removed or inserted into
the chassis without disruption to other media
blade traffic.
The design of the AT-MCF2xxx chassis allows for
multiple chassis' to be stacked, allowing two
management modules to control multiple media
chassis'. In this mode, one management module
operates as a redundant Master, only taking over
control of the stack should the Master module fail.
Additionally, chassis' can be fitted with the
AT-MCF2000S slave module, allowing multiple
chassis' to be stacked together with either one or
two AT-MCF2000M management modules
controlling the entire stack. In this manner, up to
32 x AT-MCF2000 or 16 x AT-MCF2300 chassis'
can be stacked, or a mix of either with a
maximum of 64 blade slots.
Field Maintenance
The need to simplify field maintenance was a key
criteria in the design of the AT-MCF2xxx. Each
management module is fitted with a memory card
slot, allowing network administrators to keep an
exact copy of the configuration information of a
chassis.The configuration information of the
chassis is stored not only in the management
module, but also on each blade. If a management
module fails, a replacement blade can be hot
installed into the chassis, and it can assume all the
configuration parameters of the failed unit.
Similarly, if a media blade fails, this can be hot
swapped with a replacement, and the replacement
will adopt the parameters of the failed unit.These
features ensure that an engineer sent to site can
quickly and easily get a faulty chassis back to an
operational mode.

MissingLink™ (SML)
The MissingLink
TM
on the media converter blade to pass the 'Link'
status of their connections to each other. When
the media converter detects a problem with one
of the ports, such as the loss of connection to a
node, it shuts down the connection to the other
port, thus notifying the node that the connection
has been lost.The Smart MissingLink
feature provides the same function as
MissingLink
TM
with one additional feature that
when a link is lost on a port, the Link LED of the
port which still has a valid connection to its end-
node starts to blink.These features allow network
administrators to quickly troubleshoot network
problems.
Future Proof Design
The AT-MCF2xxx chassis has been designed to
support a wide range of media blades, allowing an
installed chassis to be field upgraded as the
network grows. Planned blades include support
for IEEE 802.3ah 'Ethernet in the First Mile' as well
as high performance Gigabit blades.

cards offer free technical support, ensuring
trouble-free installation.
