Description of Hardware
Ethernet Ports
The base unit contains 24 10BASE-T / 100BASE-TX ports. It also
has two slots on the rear panel for optional 100BASE-FX or Gigabit
uplink modules. The 100BASE-FX modules have one single-mode
(SC-type) or multimode (SC-type) port. The Gigabit modules have
one 1000BASE-SX (SC-type), 1000BASE-LX (SC-type), or
1000BASE-T (RJ-45) port.
All RJ-45 ports on the base unit operate at 10 or 100 Mbps, and
support auto-negotiation of speed, duplex mode (i.e., half or full
duplex), and flow control. The RJ-45 ports also feature automatic
MDI/MDI-X operation, so you can use straight-through cables for
all connections. The 100BASE-FX modules operate at 100 Mbps,
full duplex. The 1000BASE-SX, 1000BASE-LX and 1000BASE-T
modules operate at 1 Gbps, full duplex. All modules support
auto-negotiation for flow control. Note that when using
auto-negotiation, the speed, transmission mode and flow control
can be automatically set if this feature is also supported by the
attached device. Otherwise, these items can be manually
configured for any connection.
The base unit also includes a display panel for key system and
port indications that simplify installation and network
troubleshooting.
