Removing the Optional Chassis Rail
If you are installing a card in one of the two lower-most card slots (or the bottom card, in
the case of an XG2N module), you will need to remove the optional chassis rail. To do
this, unscrew the five Phillips screws, as shown in Figure 4-2. (If you are not installing a
card into one of the lower-most card slots, or your module is not slide-rail mounted, you
will not need to perform this step.)
Caution: The module may or may not have a factory-installed IO10 card, which
always comes installed in the lowermost slot. To prevent damage to your system,
only a trained SGI service support engineer can install or remove an IO10 card.
