xSeries 440 Planning and Installation Guide

For information about the attributes, consult the online help. However, some
explanation is warranted here:

Current Speed, Max Slot Speed: As described in 1.8, “PCI subsystem” on
page 23,
the adapters installed in this slot and other slots in the same bus
dictate the speed that the slot will run at. Consequently, the current speed of
the slot may not be the maximum possible speed. The “X” in the Current
Speed value indicates the slot is running in PCI-X mode (as opposed to
running in PCI mode).

Some RXE-100 slots may indicate “NS” for the slot speed (see Figure 5-6 on
page 136 f
or an example). NS stands for “not set”. These are even-numbered
slots when the odd-numbered slot in the pair is running at 133 MHz. This is
because if both slots in a pair are used, the maximum speed of both slots is
100 MHz.

PME Signal: PME (power management events) is a hardware signal that
some PCI slots can supply. Most PCI cards do not implement PME and the
x440 and RXE-100 slots do not support PME.

Bus Number: a system-assigned number for each bus. Useful for identifying
slots that are on the same bus, but the bus number does not correlate to the
slot numbers.

Low Profile: The slot

only

supports cards that have a half-height end plate.

See the PCI Special Interest Group specifications of low-profile PCI adapters

.

LED Status: Table 5-1 shows the possible LED status messages and their
meanings:

Message

Meaning

Recommended Action

OK (no error)

None of the other conditions exist.

None

Hot eject successful

Adapter removal completed without
error.

None

Bus speed mismatch

A second adapter was hot-added
but its rated speed does not match
the current speed of the bus. The
new adapter is held inoperative.

Either:

Move one of the adapters to an empty
bus, or a bus with an adapter of the
same speed.
Reboot the server and the bus will
slow down so that both adapters can
operate.

Power fault on card in
slot

Adapter has short-circuit or other
problem preventing normal
operation.

Remove the adapter and have it repaired
or replaced.
