General Information
Congratulations on your choice of a Trimm Technologies Enclosure. The UR8J series of enclosures are
intended for rack-mounted applications. The UT8J series of enclosures are tower types for desktop
(deskside) applications. Both types of enclosures support up to eight (8) 3.5” SCSI hard drives. The drives
are to be mounted in drive canisters (modules), which accommodate standard or low profile SCA-2 style
drives. The enclosure provides power and cooling for up to eight drives of the 10,000 RPM class of hard
drives. The canister has been designed to accommodate the rotational characteristics of the 10,000 RPM
category of drives, while providing for fully seating the drive’s connector into the enclosure’s backplane.
Description
The enclosure (chassis) has been designed for Field Replaceable Units (FRU’s) to be interchangeable
between the different units within the family. The enclosure is a midplane (backplane) design with dual
redundant (N+1), hot pluggable power supplies and redundant (N+1) cooling. Likewise, the drive
canisters are hot-pluggable, plugging in from the front of the enclosure.
While the design has a mid-plane, no active components are on the mid-plane. All active components are
on/in pluggable FRU’s, which are accessible either from the front or rear of the enclosure. The N+1
design, along with the pluggable FRU’s provides for maximum uptime.
The drives, accommodated by this family of enclosures, are those that conform to SCSI-3 specifications
with SCA-2 connections. The single-ended and host only low-voltage differential (LVD) versions support
drives up through SCSI-3 Fast 20 (Ultra) for transfer rates up to 40 MB/s, while the LVD native (Host
and Drive) supports SCSI-3 Ultra 2 transfer rates up to 80 MB/s.
The drives must meet the SCSI specifications for bus loading to work properly in an Ultra SCSI
environment. The drive must mechanically comply with the Small Form Factor (SFF) committee (SCSI
working committee) dimensional specifications for SCA drives (or in the alternate, Seagate dimensional
specifications for SCA drives).
Each drive is mounted into a canister (module) and is attached from the bottom. The drive is mounted in
the canister such that the drive connector is fully seated in the midplane (backplane) when the canister
handle is closed and latched into the enclosure. Noting that the drive canister is hot-pluggable, the drive is
not spun down prior to unplugging. To remove a drive, the canister handle is opened (released) from its
latch. Opening the handle on the canister disengages the drive’s connector from the enclosure’s
connector, thereby removing power from the drive, which will then permit the drive to spin down. The
person removing the drive should wait at least ten (10) seconds after opening the handle, for the drive to
spin down, before removing the canister from the enclosure.
First - Unpack, Inspect and Check:
Unpack the enclosure and visually inspect it for damage that may have occurred during shipment. Retain
the shipping carton in case reshipment is necessary.
Check your Drive Manual for inspection, installation and setup information.

Drive Type(s) Supported:
•3.5” full-size (1.65” H) and low profile (LP) (1.00” H) (25mm).
•Hard drive rotational speeds up to 10,000 RPM.
•Using a Single Connect Attach (SCA-2) type connector (80pin).
•Low Voltage Differential (LVD) interface, with transfer abilities up to SCSI-3 Ultra
2, at 40 Mhz for data transfer rates up to 80 MB/s (wide interface). also supported are
Single-Ended drives, however, while Ultra 2 permits a mix of LVD and Single-
ended, as soon as one single-ended device is connected into the SCSI bus, ALL of the
transfer rates and cable distances revert to the lowest common denominator, the
single-ended specifications.
•Drives conforming to the Industry Standard Small Form Factor (SFF) committee
specifications for size and mounting criteria.
Host Connection(s) (Reference Figure 1)
Provides two separate host channels. The host connection is via HD68 type connectors, with each channel
daisy-chaining through four (4) drives in the enclosure, then out to the second connector at the
rear of the enclosure. This second connector must be terminated or daisy-chained to a point that is
terminated.
The enclosure contains two channels of four (4) drives. To set up a configuration of 1 channel of
8 drives or 2 channels of 4 drives, see “Convert 2 x 4 Configuration to a 1 x 8 or vice versa”.
The host connections, are identified as SCSI A and SCSI B. SCSI A is on the right side (rack) or top
(tower), (rear view), with SCSI B on the left side (rack) or bottom (tower), (rear view). Viewing
the enclosure from the front, SCSI A connects to the four (4) drives starting from the left side of
the enclosure. SCSI B connects to the four (4) drives starting with drive bay number five (5),
counting from the left.
The drive addresses are established based on a base address that is set via the Base Address Switch for
each channel. The switches are located at the rear of the unit. SCSI A base address switch sets the
base address for the drive in the bay at the far left (rack) or top (tower), (viewing from the front),
with the next three (3) bays having addresses that are incremented by one for each bay. SCSI B
base address switch sets the base address for the 5th drive bay, counting from the left (top), with
each subsequent bay incrementing by one. SCSI B base address sets the base address for these
drives, even if the interface has been jumpered for a one channel by eight drive configuration.
(NOTE: when setting drive addresses, the host address is normally set to 7).
(NOTE: the drive address switches control their respective bank of drives regardless of the
interface configuration, such as a 1 x 8 or 2 x 4 configuration.

Figure 1
Connection Illustration
Convert 2 x 4 Configuration to a 1 x 8 or vice versa:
To convert either way, either connect or disconnect a jumper cable between the 2nd connector for
the SCSI A and SCSI B connectors at the rear of the enclosure (reference Figure’s 1and 4).
For a 1 x 8 configuration, install the a SCSI jumper cable between the second connectors for the
SCSI A and SCSI B connectors. The host is connected to SCSI A, while SCSI B is either
terminated or connected to the next device in the chain (reference Figure’s 1 and 4).
For a 2 x 4 configuration, disconnect the cables between SCSI A and SCSI B connectors and
either terminate the second connector for each of SCSI A and SCSI B, or connect them to the
next device in the chain, with a terminator at the end of the chain.

Mount Enclosure into Rack (standard 19” RETMA rack):
The standard enclosure is a fixed mount configuration. Install the Rack-Mount kit supplied with
the enclosure, per the instructions supplied with the kit. Empty the enclosure (remove all canisters
and power supplies), remove the end caps from the front ears (use a screwdriver at the bottom of
the end caps to release the flexible latch), then insert enclosure into the rack and attach the front
ears of the enclosure to the rack. Reinsert power supplies and canisters.
Install Feet (Tower only)
The enclosure is shipped with three feet. Two of the feet have a self-adhesive to permit them to
be attached to the bottom (near the rear – see Figure 2). The other foot, is a stabilizer base, which
provides an anti-tip function to the enclosure. This foot is attached with the two screws included
with the foot (see Figure 2).

Install/Remove End Caps (Rack-Mount Enclosure only)
The end caps are dress items, which mount on the rail flanges at the ends of the enclosure. The
caps snap in place with a notch at the bottom of the caps. To snap the caps in place, insert the top
notch in place first and then push the bottom in until the flexible flange at the bottom is captured
in the mating indent.
The notch at the bottom, provides access for a screwdriver (or similar instrument) to be inserted
to lift up on the flexible flange to disengage it from the indent and permit the bottom of the cap to
be pulled forward to remove the cap(s).

Canister into Enclosure
Insert the canister with the drive in place in a manner similar to the above illustration. The
canister has slides on the sides to help guide the canister into position, The canister has a lever at
the front which cams the canister into the final closed position. (NOTE: To remove, the front
lever is pulled open, which disconnects the drive power. When the power is removed from the
drive it will then park the heads and spin down. After releasing the front lever, pause for
approximately ten (10) seconds to permit the drive to spin down before completing the removal).
The canister has two (2) light pipes, which carries the drive “Active” (amber/yellow) LED signal
from the midplane to the front of the canister. The red (Drive Fault) is not used.
Power Supply Install/Remove
To remove a power supply (reference Figure 4), turn the power switch “off”, remove the attached
power cord, undo the thumbscrews (two for each supply), then grab handle and pull to the rear.
To install, insert supply into opening in enclosure to point where thumbscrews engage, then
tighten thumbscrews to secure power supply in place, then attach power cord, then turn power
switch “on”. (Note, each supply has a green and a red LED to indicate if supply is good or bad –
green on = good; red on = defective supply, needs to be replaced).
Each power supply assembly also houses a fan, power switch and power connection in addition to
the LEDs. If the fan fails the red LED is activated on the supply, along with the alarm and front
panel LED to indicate a failure. The assembly as shown in Figure 4 is the lowest Field
Replacement Unit (FRU).
In a live system, use CAUTION to remove only the failed supply (the one with the red LED on).
CAUTION, with either supply removed, the air flow is misdirected and the drives will overheat
in a matter of minutes, replace supply as quickly as possible in an operating enclosure.

To remove the fan assembly (Reference Figure 4), undo the thumbscrew and pull the assembly to
the rear, by pulling on the thumbscrew. To install, push assembly into place and tighten the
thumbscrew. (Note, the fan assembly has a bi-color LED to indicate whether or not the fan is
okay; green = okay; red = fan is defective and needs replacement).
Electronic Circuit Boards
Within the enclosure, there are three (3) (four if optional Saf-Te is installed) circuit boards:
1. On the left front ear (end cap), there is an enclosure status (front display) board, which has
three (3) bi-color LEDs which indicate the status of the power supplies (top LED), enclosure
fans (middle LED) and temperature (bottom LED) within the enclosure. The temperature
LED is red if the enclosure temperature exceeds 45°C. Green indicates okay operation, while
red indicates a problem with the associated function. This board contains the audible alarm
reset switch. When an alarm is triggered, it can be deactivated by pressing the reset switch.
This board is a FRU.
For access to the Display Board , in the Rack Mount, remove the left End Cap. In the Tower
enclosure, remove the stabilizer foot (2 philips screws), then remove the cover (3 philips
screws at rear and then pull cover to the rear), next, remove the front bezel (4 Torx screws,
requires a T20 Torx bit).

2. The mid-plane (backplane) board is located approximately in the middle of the enclosure and
connects the drives to the host connection board. This board is not a FRU and is only repaired
by returning the enclosure to Trimm. Generally, this board does not contain any active
components. However, it does contain LED’s, terminator power diodes and fuses.
3. The alarm board is accessible from the rear of the enclosure. (There are two types; one in the
standard JBOD; and one for the JBOD connected in a castle (UR16R) configuration). (The
second type (UR16R) does not have a Saf-Te option as it uses a different communications
method). To remove, undo the mounting screws and pull the board out, using the metal lip
that is mounted at the rear of the board. This board contains the audible alarm circuit. The
board is a FRU. Generally, any active components that are within the enclosure are mounted
on this board. Also, the optional Saf-Te board is mounted on this board as a daughter board.
IF the optional Saf-Te board is installed, then the alarm board CANNOT be removed
from the rear, until and unless the Saf-Te board is removed.
4. The optional Saf-Te board is connected as a daughter-board to the alarm board via two
headers and is also connected to a drive channel via a separate connector. The Saf-Te board
has provisions for setting the address of the Saf-Te device to either SCSI ID 4 or 5 via an on-
board jumper, using jumper P3 (reference Figure 5). To replace the Saf-Te board requires
removing the top cover from the enclosure. With the top cover removed, lift the Saf-Te board
off of the alarm board (connected via two headers) and remove the cable connector (this
connector off disables the Saf-Te device from communicating on the SCSI bus. This board is
a FRU.
