Chapter 7 Line Card Service Procedures 7-5
6. Move your head slightly right to the next connector, and inspect its pins,
repeating Step 4 and Step 5.
7. Continue in this manner for each connector until you reach the right side of the
line card.
▼ Inspecting the Line Card iPASS Connectors
The small iPASS connectors on the line card are for the InfiniBand cables. The design
of these connectors is much simpler and more robust, so inspection is much easier.
● Check the small connectors for any debris, or cracked or bent fittings.
Most debris can be blown out. If you find a cracked or bent connector, contact
your Sun Service representative.
▼ Inspecting the Retainers
The two retainers on the line card serve three purposes:
■ Align the line card for proper insertion into the chassis.
■ Allow final insertion of the line card into the chassis and simplify the physical
connection of the line card connectors to the midplane connectors.
■ Allow extraction of the line card from the chassis and simplify the physical
disconnection of the line card connectors from the midplane connectors.
The retainer’s design is shown in
FIGURE 7-2.
● Ensure that the pieces of the retainer look finished, move smoothly, do not
bind, or do not feel loose or sloppy in any way.
