Overview

The External I/O Expansion Unit provides a host server with additional slots for PCI
cards.

■ The single I/O boat configuration provides six slots for I/O cards.

■ The optional two I/O boat configuration (FIGURE 1-1) provides twelve slots.

Note – The External I/O Expansion Unit might be abbreviated to I/O Box in

programs and manuals.

1.1.1 Chassis

The External I/O Expansion Unit chassis includes the centerplane (item 4 in

FIGURE 1-2) and two non-removable internal AC cables (item 7 in FIGURE 1-2).

There are no serviceable components inside the chassis. If the centerplane or the
internal AC cables are damaged, the chassis must be replaced.

Note – A replacement chassis does not include power supply units (PSUs) or I/O

boats. Transfer the PSUs and I/O boats from the damaged chassis to the replacement
chassis.

Each internal AC cable supplies only one PSU. To ensure redundant power, use the
two AC cords supplied with the External I/O Expansion Unit to connect the internal
AC cables to separate AC sources.

Caution – Do not connect the internal AC cables directly to a power strip. Use the

the AC power cords supplied with the External I/O Expansion Unit to connect the
internal AC cables to electrical power.

Caution – Do not substitute other AC power cords for the AC power cords supplied

with the External I/O Expansion Unit. The substitute AC power cords might not
have the same power rating.

1.1.2 Power Supply Units

The External I/O Expansion Unit has two power supply units (PSUs) for
redundancy. See

Each PSU includes an integral fan.

1.1.2.1 AC Power

The PSU slots are powered through internal AC cables that extend out of the rear of
the chassis (

FIGURE 1-2).

The PSUs do not share AC current. Connect both internal AC cables to AC power.

The internal AC cable for a PSU is the cable terminating nearest that PSU slot.

The PSUs should be connected to two independent external AC power sources so
that service will not be interrupted if one AC power source fails.

1.1.2.2 Fans

A fan is located in the front of each PSU. If one fan fails, the remaining fan supplies
enough air to cool two I/O boats.

Note – The fan might turn on when you insert a PSU into the External I/O

Expansion Unit. This is normal behavior if you are installing a second PSU while the
first PSU is powered on. The fan receives DC power through the centerplane.

1.1.3 I/O Boats

The External I/O Expansion Unit can contain up to two I/O boats (FIGURE 1-4).

Note – The maximum number of I/O boats that can be attached to a server can vary

according to the server model. See TABLE 1-1.

TABLE 1-1 Number of I/O Boats Per Server

Server Model Maximum Number of I/O Boats Supported

SPARC Enterprise T5120 Server 1

SPARC Enterprise T5140 Server 2

Chapter 1 Overview 1-7

FIGURE 1-5 Logical Layout of I/O Boats

Note – A switch is a device that connects multiple busses to a single bus.

In the I/O boat, all PCI card data passes through the link card.

When you run system diagnostics, the switches are displayed in the output of
OpenBoot PROM probing. However, the link cards themselves never appear during
OpenBoot PROM probing.

1.2 Card Slots

The card slots have the following characteristics:

■ An I/O boat has seven card slots. Slot numbers 0 through 6 are counted from left

to right.

■ Slot 0 is reserved for the link card. Slot 0 is the first slot in the left side of the I/O

boat. For information about link cards, see Section 1.2.2, “Link Kit” on page 1-12.

1-8 External I/O Expansion Unit Installation and Service Manual for SPARC Enterprise T5xxx Servers • April 2011

■ Slots 1-6 are for PCI cards. (PCI cards are sometimes known as host adapters or

host bus adapters.)

■ PCI card slots are not hot-pluggable.

■ The PCI Express I/O boat supports up to x8 card sockets. PCI Express x16 cards

are not supported in the PCI Express I/O boat.

Note – Graphics cards are not supported.

Caution – Do not insert a x16 PCI Express card in an I/O boat. The x16 card

connector is too large for the x8 card socket and will damage the socket.

1.2.1 Carriers

All PCI cards in the External I/O Expansion Unit are mounted on carriers
(

FIGURE 1-25). Carriers control RFI emissions and maintain the proper flow of air

through the External I/O Expansion Unit.

The front of each carrier is labelled with its slot number (PCIE 1, and so forth).

Note – Slot 0 is reserved for the link card. This slot is marked LINK 0.

Carriers are physically keyed to fit only specific slot numbers. The keys can be
adjusted for other slots as needed.

New carriers include dummy cards. The dummy cards help the carriers to stay in
place and to control the passage of air through the I/O boat. For information about
dummy cards, see Section 1.2.1.2, “Dummy Cards” on page 1-11.

1.2.1.1 Carrier Slots

There are seven carriers in each I/O boat (FIGURE 1-6). Carriers can be adjusted to fit
various sizes and shapes of PCI cards. Link cards use the same type of carrier.

■ Carrier slot 0 is always used for the link card.

■ Carrier slots 1 through 6 are used for PCI cards.

1.2.1.2 Dummy Cards

New carriers are shipped with dummy cards (FIGURE 1-7).

FIGURE 1-7 Dummy Card

The service labels (not shown in FIGURE 1-7) on the dummy card include simplified
instructions for removing and installing PCI cards.

Note – Be certain that the dummy cards are fully seated. This action minimizes the

vibration of unused carriers in the I/O boat slots.

Chapter 1 Overview 1-11

1.2.2 Link Kit

One link kit (FIGURE 1-8) is required for each I/O boat.

A link kit includes two link cards. One link card goes into the host server. The other
link card goes into the I/O boat. The link cards are physically identical.

A low-profile bracket is included so a link card can be used in a low-profile I/O card
slot.

FIGURE 1-8 Link Kit

Slot 0 in each I/O boat is the dedicated link card slot. Use slot 0 only for the link
card.

1.2.3.1 Minimum Bend Radius for Link Cables

The link cables might be damaged if they are coiled too tightly. The minimum bend
radius for the link cable is 1.85 in. (47 mm).

Caution – Coiling the link cables with a smaller bend radius than listed above will

break the cables.

1.2.3.2 Cable Management Unit

The cable management unit contains two support brackets and a cable plate.

The support brackets attach with screws to the rear of the system rack. The cable
plate rests on the support brackets.

The cable plate has two positions (

■ In the normal position, the cable plate rests on the support brackets.

■ In the raised position, the cable plate rests slightly above the support brackets.

FIGURE 1-11).

This position provides clearance for you to remove and replace an I/O boat.

1.3 Carriers

In the I/O boat, all PCI cards are mounted on carriers. When you insert the carrier
and card into the boat and push the carrier handle into the closed position, the
carrier mechanism automatically seats the PCI card.

FIGURE 1-12 shows a carrier with an attached PCI card.

Note – The service life of a carrier is at least 100 PCI card insertions. To avoid

premature failure of the carrier, do not repeatedly open and close the carrier more
than is necessary to familiarize yourself with its operation.
