Producent Allied Telesis
Part nummer AT-8948A-50
Omschrijving AT-8948, Managed Switch, Multi-Layer, 48x 10/100TX + 4x SFP
GBIC bays, Rackmount, Internal PSU
  1U form factor allows optimum use of rack space and thus higherdensity of ports per rack. Front-to-back cooling for optimum rack/cabinet airflow. Operating temperature extends to 50C (122F).Policy based QoS ensures performance of delay-sensitiveapplications. Internal dual hot-swappable AC or DC load-sharingpower supplies remove the need for an expensive, rack-space-wastingRPS.

Product specificaties ***
Omschrijving 10/100 x 48 ports managed Fast Ethernet Layer 3 switch with 4 SFP expansion bays
The AT-8948 is one of the most advanced Fast Ethernet switches available. An upgrade path to IPv6, fine service provisioning, and QoS features make the 8948 a smart choice when your network needs comprehensive control over service quality and bandwidth.

The AT-8948 supports dual hot-swappable power supplies and the front-to-back airflow optimizes switch cooling. You can add a hardware-based IPv6 card for added line rate support. The AT-8948 meets the performance and IPv6 transition needs of your network.
