Troubleshooting guide

• If your Myrinet-2000 M3-E* switch is equipped with a monitoring line card

(located in the top-slot of the switch), this monitoring line card contains 10base-T

dual ethernet ports and DHCP is required for its installation.

• A Myrinet-2000 switch does not require any configuration.

• Switch line cards (M3-SW16-8E, M3-SW16-8F, M3-SPINE-8F, M3-BLANK) are

hot-swappable.

• A line card, a fan tray, or an enclosure is a Field Replaceable Unit (FRU). The

power supply is not an FRU; it is built into the enclosure.

• We recommend the use of dust plugs in unused ports on the switch, and require

blank panels in unused slots (for cooling and EMI reasons).

• You must provide proper ventilation for the switch(es), otherwise shutdown due to

overheating could occur.

After reading the documentation on the Myrinet-2000 Switches for Large Clusters, you

should be aware of the following important information and precautions pertaining to

M3-CLOS-ENCL-* and M3-SPINE-ENCL-* switches:

• Each M3-CLOS-ENCL-* and M3-SPINE-ENC-*L switch is equipped with a

monitoring line card (located in the left-most-slot of the switch), and this

monitoring line card contains 10/100base-T dual ethernet ports. Assigning a static

IP address or DHCP is required for its installation.

• A Myrinet-2000 M3-CLOS-ENCL-* or M3-SPINE-ENCL-* switch does not require

any configuration.

• For the M3-SPINE-ENCL-* enclosure, the M3-THRU-16Q switch line cards must

be inserted in odd-numbered slots of the enclosure, and the M3-4SW32-16Q switch

line cards must be inserted in the even-numbered slots of the enclosure.

• For the M3-CLOS-ENCL-* enclosure, if there are M3-THRU-16Q and M3-4SW32-

16Q switch line cards in the middle slots (slots 8-11), the M3-THRU-16Q switch

line cards must be in slots 8 and 9, and the M3-4SW32-16Q switch line cards in

slots 10 and 11.

• Switch line cards (M3-SW32-16F, M3-2SW32, M3-4SW32-16Q, M3-THRU-16Q,

M3-AIRDAM) are hot-swappable.

• The M3-CLOS-ENCL (or M3-SPINE-ENCL) enclosure contains four 350W power

supplies that can be individually hot-swapped, and operate in an auto-parallel

mode in which any three power supplies are sufficient to supply the maximum

power a unit may require.
