MCF2xxx SERIES

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.

| Fast Ethernet Media Converters

MissingLink

MissingLink™ (SML)

The MissingLink

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

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.

Hassle Free Support

All Allied Telesis Ethernet media converter line

cards offer free technical support, ensuring

trouble-free installation.
