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 for 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 at http://www.pcisig.com/data/specifications/lowp_ecn.pdf. LED Status: Table 5-1 shows the possible LED status messages and their meanings: Table 5-1 LED status messages Message Meaning Recommended Action OK (no error) None of the other conditions exist.

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

”

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

“

”

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

“

”

for the slot speed (see Figure 5-6 on

page 136 for 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.

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

meanings:

OK (no error)

None of the other conditions exist.

Adapter removal completed without

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.
