12-Port Ethernet™ Repeater Hub
Twisted Pair Connector/10BaseT Connection
To connect 10BaseT Cable to Model 1004 Repeater RJ-45 connectors:
1. Locate or build 10BaseT cables that are:
•
802.3 compliant (See page 18)
•
correct (straight through or crossover) cable configuration
for site installation (See page 6)
•
male RJ-45 plug
2. Connect male RJ-45 plug connector at one end of 10BaseT
cable to Model 1004 Repeater Hub RJ-45 jack connector.
NOTE: Use MDI Switch to change polarity of RJ-45 cable at Port 1.
3. Connect male RJ-45 plug connector at other end of 10BaseT
cable to DTE terminal RJ-45 jack connector (using Port 1 and

Installing Slide-In Cards
CAUTION: Wear a grounding device and observe electrostatic
discharge precautions when installing Slide-In Cards. Failure to
observe this caution could result in circuit board failure.
NOTE: Slide-in Cards can be hot-swapped.
To install a Slide-In Card:
1. Determine if the Slide-In Cards has an SQE switch and, if so,
verify that the SQE switch is in the OFF position:
NOTE: SQE switches must be set to the following OFF
positions:
•
UTP/STP card
TOWARD 20-pin edge connector
•
Thinnet card
TOWARD 20-pin edge connector
•
AUI-DCE
AWAY FROM 20-pin edge connector
•
AUI-DTE card
Not Applicable
•
Fiber Optic card
TOWARD 20-pin edge connector
•
Redundant Fiber Optic
SQE jumper setting on board should be
labeled; if not, holding card with 20-pin edge
connector at top, jumper two leftmost pins.
•
Bridge
Not Applicable
2. With the Slide-In Card components facing up, carefully guide
the Slide-In Card along the card guides until the Slide-In Card
connector meets the the Model 1004 Repeater Hub backplane.
3. Firmly push the card into the slot until the Slide-In Card
faceplate is flat against the Model 1004 Repeater Hub frame.
4. Rotate the Slide-In Card thumbscrews into the Model 1004
Repeater Hub threaded holes.
