Before You Begin
Before going through with this manual, you should read and focus on the following
safety guidelines. Notes about the subsystem’s controller configuration and the
product packaging and delivery are also included.
Safety Guidelines
To provide reasonable protection against any harm on the part of the user and to
obtain maximum performance, user is advised to be aware of the following safety
guidelines particularly in handling hardware components:
Upon receiving of the product:
Place the product in its proper location.
To avoid unnecessary dropping out, make sure that somebody is around for
immediate assistance.
It should be handled with care to avoid dropping that may cause damage to the
product. Always use the correct lifting procedures.
Upon installing of the product:
Ambient temperature is very important for the installation site. It must not
exceed 30°C. Due to seasonal climate changes; regulate the installation site
temperature making it not to exceed the allowed ambient temperature.
Before plugging-in any power cords, cables and connectors, make sure that the
power switches are turned off. Disconnect first any power connection if the power
supply module is being removed from the enclosure.
Outlets must be accessible to the equipment.
All external connections should be made using shielded cables and as much as
possible should not be performed by bare hand. Using anti-static hand gloves is
recommended.
In installing each component, secure all the mounting screws and locks. Make
sure that all screws are fully tightened. Follow correctly all the listed procedures
in this manual for reliable performance.
Controller Configuration
This RAID subsystem supports single controller configuration.
Packaging, Shipment and Delivery
Before removing the subsystem from the shipping carton, you should visually
inspect the physical condition of the shipping carton.
Unpack and verify that the contents of the shipping carton are complete and in
good condition.
Exterior damage to the shipping carton may indicate that the contents of the
carton are damaged.
If any damage is found, do not remove the components; contact the dealer where
you purchased the subsystem for further instructions.

Chapter 2 Physical Components
2.1 Controller Module
The EP-2126-SS includes a U320 SCSI-to-SCSI Controller Module.
2.1.1 Controller Module Panel
The Controller Module has 6 major parts: Host Channel, UPS Port, RS-232 Port,
Ethernet Port, Alarm Mute Button, and a Hard Contact Relay. These parts are
described as follows:
1. Host Channel
The subsystem is equipped with 2 host channels (Host channel A and Host
channel B), with two 68-pin SCSI connectors at the rear of the subsystem, for
SCSI in and out.
2. Uninterrupted Power Supply (UPS) Port
The subsystem may come with an optional UPS port allowing you to connect a
UPS device. Connect the cable from the UPS device to the UPS port located at
the rear of the subsystem. This will automatically allow the subsystem to use
the functions and features of the UPS.

3. RS-232 Port
The subsystem is equipped with a serial monitor port allowing you to connect to
a PC or terminal.
Below are the RS-232 settings.
Settings
Baud Rate 115200
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
4. R-Link Port : Remote Link through RJ-45 Ethernet for remote
management
The subsystem is equipped with one RJ-45 10/100 Ethernet port. You can use
Java-based browser to manage the RAID subsystem through Ethernet for
remote configuration and monitoring.
Link LED: Green LED indicates Ethernet is linking.
Access LED: The LED will blink orange when the 100Mbps Ethernet is being
accessed.
5. Alarm Mute Button

2.2 Power Supply / Fan Module
Every EP-2126-SS contains two 300W Power Supply / Fan Modules. All PSFMs
are inserted into the rear of the chassis.
Each PSFM delivers Full-Range (90 – 254V) AC voltage of electricity. The EP-2126-
SS normally operates with two PSFMs running. Note that each PSFM consists of 1
power supply, and 1 fan.
2.2.1 PSFM Panel
On the back of the Power Supply/Fan Module, there are three distinct features: the
Power On/Off Switch, the AC Inlet Plug, and a Power On/Fail Indicator showing the
Power Status LED, indicating ready or fail.
Each fan within a PSFM is powered independently of the power supply within the
same PSFM. So if the power supply of a PSFM fails, the fan associated with that
PSFM will continue to operate and cool the enclosure.

SCSI to SCSI RAID Subsystem
User Manual 19
2.2.2 Power Supply Module LED
When the power cord connected from main power source is inserted to the AC
Power Inlet, the power status LED becomes RED. When the switch of the PSFM is
turned on, the LED will turn GREEN. When the Power On/Fail LED is GREEN, the
PSFM is functioning normally.
2.2.3 Fan of PSFM
Each PSFM has 1 Master Fan.
The Master Fan is located beside the PSFM panel.
MasterFan
NOTE: In the LCD display, Master Fan of Power Supply Unit A is shown as
“MF/PSU-A. Master Fan of Power Supply Unit B is “MF/PSU-B”.

2.2.4 Power Supply Installation
In this section, you will be shown how to install the Power Supply.
a. Check for damage, especially to the PCB Golden Fingers at the rear of the
Power Supply.
CAUTION! Handle the module with care and avoid damaging
the Golden Fingers. In addition, make sure there are no
fingerprints on the Golden Fingers. Do not install the module
if the Golden Fingers are damaged.
b. With the Power Supply handle in the open position, carefully insert the module
into the enclosure.
c. Manually close the Power Supply handle.
IMPORTANT! To secure the Power Supply to the
enclosure, tighten the thumb screws.
d. Connect the Power Supply cord from the power source to the AC Power Inlet.
IMPORTANT! For safety reasons, make sure the power
switches are turned off when you plug-in the power
cords. When removing the power cords, ensure that the
switch on the back of each power supply fan module are
turned off and the power on/fail LED are red.
