400-4TX MDA
Not supported on the Accelar Series Modules (see
Table 2 on page 2)
•
8100-4TX MDA
Supports BayStack 350/450, BayStack 410, and
Accelar Series Modules (see Table 2 on page 2)
Both models use four 10/100BASE-TX RJ-45 (8-pin
modular) port connectors to attach Ethernet devices.
The RJ-45 ports are configured as media-dependent
interface-crossover (MDI-X) connectors. These ports
connect over straight cables to the network interface
controller (NIC) card in a node or server, similar to a
conventional Ethernet repeater hub. If you are connecting
to another Ethernet hub or Ethernet switch, you need a
crossover cable unless an MDI connection exists on the
associated port of the attached device.
The 10/100BASE-TX MDA ports can operate at either 10
Mb/s or 100 Mb/s. The port speed is determined through
autonegotiation with its connecting device.
Table 3 describes the 10/100BASE-TX MDA components
and LEDs.
