Magnum Personal Hubs
1.0
SPECIFICATIONS
1.1.
Technical Specifications
Performance:
Data Rate: 10 Mbps
Partitioning: Enforced after 32 consecutive collisions.
Reconnect: Occurs after 512 bits error-free transmission.
Maximum Ethernet Segment Lengths:
10BASE-T (Unshielded twisted pair)
10BASE-T (Shielded twisted pair) - 150m (492 ft)
AUI Drop Cable
Network Standards:
Ethernet V1.0/2.0 IEEE 802.3: 10BASE-T, 10BASE5.
(Magnum Personal Hubs are physical layer standard Ethernet
operate in networks independently of all software.)
Operating Environment:
Ambient Temperature: 32ºF to 122ºF (0ºC to 50ºC)
Storage Temperature: -20ºC to 60ºC
Ambient Relative Humidity: 10% - 95% (non-condensing)
Power Supply (External):
Power Input: 95 - 125 vac at 60 Hz for "-d" Models,
200 - 250 vac at 50 Hz for "-i" Models, which have
IEC power cable connector in the external power unit.
Power Consumption: H40A, H50: 6 watts max.; H80A,
H90: 10 watts max.
Connectors:
H40A: 4 front shielded RJ-45 (1 with up-link switch), 1
rear AUI, female with slide lock.
H50: 4 front shielded, RJ-45, 1 rear shielded RJ-45 with
up-link switch.
H80A: 8 front shielded RJ-45 (1 with up-link switch), 1
rear AUI, female with slide lock.
H90: 8 front shielded RJ-45, 1 rear shielded RJ-45 with
up-link switch.
(Shielded 10BASE-T connectors accept either unshielded
wiring lugs for standard twisted pair media wiring.)
The regular RJ-45 ports support the standard for hubs-to-users twisted pair wiring: pin 1= receive+, 2 =
receive-, 3 = transmit+, 6 = transmit-, other pins not used. The RJ-45 port with the MDI-X switch is
normally the same, but when switched it supports the standard for up-links using twisted pair wiring, i.e., the
transmit and the receive pairs are exchanged: pin 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive- ,
other pins not used.
