HP AdvanceStack 100Base-T Hub-8TXE (J3235A) Repeater

Funkcje:

· Transmits data at 100 Mbits/s for demanding applications
· Conforms to the IEEE 802.3u repeater specification for 100Base-TX
· Provides 8 RJ-45 100Base-TX ports (using MDI-X wiring)
· Port 8 can serve as an MDI-X port (for connection to network devices such
as workstations or servers) or as an MDI daisy-chain port (for connection to
network devices such as hubs or switches), eliminating the need for
crossover cables
· Supports 100W Category 5 shielded or unshielded cable (STP or UTP)
· Friendly design that monitors network utilization, collisions, link and port
partition status
· LED indicator panel includes Utilization and Collision rate indicators for
reporting hub activity and facilitating problem diagnosis
· Automatically partitions bad ports to protect the network system
· Automatic polarity detection and correction permits automatic adjustment
for wiring errors
· Plug-and-play operation
The HP Hub-8TXE also supports the following basic system safeguards:
· This hub features automatic partitioning and reconnection, jabber lockup
protection, and automatic polarity detection for network cabling.
· With automatic partitioning and reconnection, any port is automatically
isolated if excessive collisions occur on it. When the condition is corrected,
the port is automatically reconnected.

Product Overview 1-3
· With the jabber lock-up function, the hub automatically stops transmission
of abnormal Ethernet frames that may cause data loss for all network users.
(Jabber refers to abnormal Ethernet frames which are much too long and
may come from a malfunctioning Ethernet card.)
· With automatic polarity detection, the hub recognizes and adjusts for
attached cable assemblies which may be wired with incorrect polarity on the
receive pair.
