Hardware Features
Hardware features of the AT-8400 Series switch include:
13 slots — 12 slots for line cards, such as Fast Ethernet and Gigabit
Ethernet cards, and one slot for the AT-8401 management card
One pre-installed AC or DC power supply (depending on the
chassis model)
One expansion slot for a redundant power supply
One AT-8401 management card that supports the following
management access methods:
Local (out-of-band) management using the RS-232 port on
the card
Remote (in-band) management using Telnet, a web browser,
or an SNMP application program
Software Features
Some of the software features of the AT-8400 Series switch and line
cards include:
AT-S60 management software — features menu, web browser,
and command line interfaces
Enhanced stacking — simplifies network management by
allowing you to manage multiple AT-8400 and AT-8000 Series
switches from one management session
BOOTP and Dynamic Host Configuration Protocol (DHCP) —
automatically loads internet protocol (IP) configuration
information onto the AT-8400 Series switch
Port-based and tagged VLANs (IEEE 802.1Q) — creates
independent traffic domains
Basic VLAN mode — forwards packets by MAC addresses only
Auto-Negotiation (IEEE 803.3u compliant) — automatically sets
port speed and duplex mode
Spanning tree protocol (IEEE Std 802.1D), rapid spanning tree
protocol (IEEE Std 802.1w), and multiple spanning tree protocol
(IEEE Std 802.1s)— detect physical data loops in a network
topology and blocks ports of redundant paths
