Adapter is installed in slot P1-C49
Backup power module is installed in slot P1-49-E1
Voltage
12 V
Cables
One mini-SAS HD Y cable (part number: 01GY461) connects the two storage backplane connectors
(J1 and J2) to the P1 connector on the PCIe3 x8 cache SAS RAID internal adapter 6 Gb in slot P1-
C49.
One SAS cable (part number: 01ML060) with mini-SAS connectors and an external SAS port is
attached to rear P2 connector of the PCIe3 x8 cache SAS RAID internal adapter 6 Gb.
Important requirements for adapter installation
An automatic sector conversion takes place for use with the new adapter when migrating existing SAS
disk enclosures and devices from existing previous PCIe SAS adapters to PCIe3 SAS adapters. For more
information about the migration procedures, see Upgrading a SAS RAID storage adapter.
Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
• The latest version of the device driver or IBM Power RAID adapter utilities (iprutils) can be downloaded
from the IBM Service and Productivity Tools website (http://www14.software.ibm.com/webapp/
set2/sas/f/lopdiags/home.html).

PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter (FC EJ1N and EJ1P; CCIN 57B3)
Learn about the specifications and operating system requirements for the feature code (FC) EJ1N and
EJ1P adapters.
Overview
FC EJ1N and EJ1P are both the same adapter with different tail stock brackets. FC EJ1N is a low-profile
adapter and FC EJ1P is a full-height adapter. FC EJ1N and EJ1P are functionally identical to FC 5901 and
5278, but designates to IBM configurator tools that the usages are only supported for tape and DVD, not
disk.
The PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter is a PCI Express (PCIe) generation 1 (Gen1), x8
adapter. The adapter is for high-performance, high-density, and serial attached SCSI (SAS) applications.
It supports the attachment of SAS tape and DVD by using a pair of mini-SAS 4x connectors. The mini-SAS
4x connectors allow the adapter's eight physical links to be used in various narrow and wide-port
configurations. The adapter can also be used for some external tape drive models, which are not
supported on the newer and faster four-port 6 Gb PCIe3 adapters. The adapter does not have write
cache.
The PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter is a 64 bit, 3.3 V, bootable SAS adapter.
Externally attached devices are designed to run at a data rate of 1.5 Gbps for serial ATA (SATA) devices,
and 3 Gbps for SAS devices.
