Installing Slide-In Cards (SICs)
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: SIC card configured RI/LI MUST be installed in RI/LI SIC slot;
SIC card configured RO/LO MUST be installed in RO/LO SIC slot.
To install a Slide-In Card:
1. Determine if Slide-In Card has RI/LI-RO/LO switch and, if so,
determine if RI/LI-RO/LO switch is in correct position for the
installation. If necessary, reset RI/LI-RO/LO Switch.
NOTE: RI/LI-RO/LO switch settings are marked on Slide-In
Card component surface.
NOTE: Fiber SIC does NOT have RI/LI-RO/LO switch.
2. With Slide-In Card components facing up, carefully guide
Slide-In Card along card guides until Slide-In Card connector
meets Token Ring Multi-Media Repeater backplane.
3. Firmly seat Slide-In Card against internal connector until
Slide-In Card faceplate is flat against Token Ring Multi-Media
Repeater frame.
4. Rotate Slide-In Card thumbscrews into Token Ring Multi-
Media Repeater threaded holes.
