AT-8948
| MultiIayer IPv4 and IPv6 Switch
Reliability
Dual internal hot-swappable load-sharing power
supplies provide ultimate space-saving reliability
and redundancy for maximum service uptime.
Both 110/240VAC and -48VDC PSU versions
are available.There is no requirement for an
external RPS, and combined with front-to-back
cooling and a 1RU height, the AT-8948 is
perfect for the high-density rack environment
where conditions are demanding and space is
at a premium.
Flexibility
Four hot-swappable gigabit SFP uplink ports can
be aggregated to provide a total of 4Gbps of
uplink bandwidth, and can support any
combination of gigabit copper, or short haul and
long haul fiber SFP modules.This flexibility of
uplink interface options caters for multiple
applications and connectivity requirements.
Power to Perform
The AT-8948 top-of-the-line multilayer switch is
built to meet the needs of high performance
network services.Together with Allied Telesis'
advanced software feature set,AlliedWare, the
AT-8948 is a superior access switching solution,
bringing true intelligence to the edge.
