Hardware Installation
This chapter describes how to install your DSE4XM hardware.
Your DSE4XM includes a DXH510 PCI Express host adapter card and two 1-meter
CX4 cables. These components support a x8 connection between the DSE4XM chassis
and one server, which is the standard shipping configuration for the DSE4XM.
The DSE4XM supports additional configurations accommodating connections to up to
four servers, with a fixed amount of storage allocated to each server. Each additional
server requires a DXH510 adapter card and cable to connect to the DSE4XM chassis.
Allocation of memory to each server is specified at the time the product is ordered and
pre-configured at the factory. Dual x8 connection to a single server also requires an
additional DXH510 and factory pre-configuration. Please contact Dolphin customer
support at http://www.dolphinics.com/support

Caution:
For protection of the StorExpress devices, we recommend that you do not attempt to
service or remove the cover of your DSE4XM chassis. However, if you do, power should
be disconnected from the chassis prior to servicing the chassis or removing the cover
for any reason. In or der to disconnect power remove the power cord from its receptacle
in the back of the chassis as shown in Figure 2–1. The front power switch is not a disconnect switch for system power.
2.2 Installing DXH510 Card in Server
The DXH510 host adapter card is shown in Figure 2–3. The connector ports P0 and P1
are labeled in this figure.

Caution:
Electrostatic dischar ge (ESD) can damage electro nic components. Be sure that you are
properly grounded prior to any hardware installation procedure using an ESD
protection device such as a wrist strap.
If you are installing the DXH510 in a low-profile system and need to use the half-height
bracket, please refer to the Section 2.2.1.
1. Locate the serial number on the back of your DXH510 and record it for future reference.
2. Power off the server and disconnect the power cable.
3. Remove the server's access panel. Locate an available PCIe slot.
–Consult your server's documentation for details on removing the panel and
identifying PCIe slots.
Note: Your DXH510 is designed for use in a x8 PCIe slot. It will work in a x16 slot, but this
does not improve performance. Your DXH510 can also work in a x2 or x4 slot but
performance may be diminished in a x2 slot, or in a x4 slot if a x8 connection is
intended.
4. Follow server manufacturer’s instructions for installing PCIe add-in cards.
5. Replace the server’s access panel
6. Plug in the server’s power cable

You have completed the hardware installation of the DXH510 into the server. If you are
connecting multiple servers to the DSE4XM chassis, repeat this process for each server.
Each server requires a DXH510 host adapter to connect to the DSE4XM chassis. If you
are making a dual x8 connection to a single server, locate a second PCI Express slot and
install the second DXH510 adapter.
2.2.1 Half-height Bracket Installation
For installation in a low-profile server, the full-height bracket must be replaced with the
half-height bracket.
Caution: Electrostatic discharge (ESD) can damage electronic components. Be sure that you are
properly grounded prior to any hardware installation procedure using an ESD
protection device such as a wrist strap.
1. Locate the half-height bracket in the DSE4XM package
2. Remove the four screws, indicated in Figure 2–4, that hold the full-height bracket
to the DXH510. Do not attempt to remove the bracket until the screws have been
fully removed.
3. Remove the bracket carefully from the device.
4. Align the connectors on the DXH510 with the openings in the half-height bracket:
Be sure the bracket tabs are on the backside of the device.
5. Adjust the bracket so that the notches on the bracket tabs fit around the guides on
the back of the card. The bracket guides are illustrated in Figure 2–4.
6. Attach the half-height bracket using a screwdriver to tighten the four screws. Do
not overtighten the screws as this can damage the device.
7. Return to Step 2 of Section 2.2.

2.3 Connecting the DXH510 to Chassis
A server connects to the DSE4XM chassis using the DXH510 PCI Express host adapter
card. One or two cables are used to connect the DXH510 to the DSE4XM chassis. One
cable provides a x4 (8 Gbps) connection; two cables provide a x8 (16 Gbps)
connection.
Two 1-meter cables (Model DXC1M-A) are provided as a part of the standard
DSE4XM package. Additional compatible cables are available from Dolphin for
connecting the DXH510 to the DSE4XM chassis, as listed in Table 2–2. See http://
www.dolphinics.com/support for the most up to date compatible cable offerings.

The DSE4XM chassis has two pairs of connectors (four total), which are used to cable
to the DXH510 host adapter. As shown in Figure 2–1 on Page 9, one set of connectors
is located at Uplink Slot 0; the second set of connectors is located at Uplink Slot 1. The
lower connector is P0 and the upper connector is P1.
March 10, 2009Dolphin Interconnect Solutions13
www.dolphinics.com
One set of connectors can be used for a x8 connection when cabled to a single
DXH510, or for two x4 connections when each connector in the set is cabled to a
different DXH510 adapter card. Two sets of two connectors allow for connection to up
to four DXH510 adapter cards in this manner.
Each DXH510 card has one pair of connectors, as shown in Figure 2–1 on Page 9. Both
connectors are used for a x8 connection, or a single connector may be used for a x4
connection.
Table 2–3 shows how the DXH510 card(s) are cabled to the DSE4XM for
configurations of one to four servers.
Table 2–3 DXH510 to DSE4XM Chassis Cable Connections
Only required if a x8 connection is desired. May be left unconnected if a x4 connection only is needed.
The single server dual x8 configuration is similar to the two server configuration,
however in this case both DXH510:1 and DXH510:2 adapters reside in the same server.
Attach the cable(s) to the required connectors for your configuration as specified by
Table 2–3.
