Replacing a J4400 Array Chassis
This document describes replacement procedures for the Sun Storage J4400 Array
chassis.
Caution – Only trained service personnel should remove the covers on this
equipment.
This product is intended for restricted access whereby access is controlled through
the use of a means of security (for example, key, lock, tool, badge access), and
personnel authorized for access have been instructed on the reasons for the
restrictions and any precautions that need to be taken.
Prerequisites
Before you start to replace a failed chassis, you must:
■ Back up all data stored on the array.
■ Stop all system I/O to the array.
■ Verify that the failed chassis is ready to be removed.
■ Prepare the work site and observe all “ESD Precautions” on page 2.
■ Remove all power from the chassis and chassis components.
Verifying a Chassis Failure
To determine that a chassis has failed, check the following:
■ The array System Power/Status LED (front) is amber.
1
■ The audible alarm is sounding.
■ All of the component fault LEDs are green.
■ Disk drive ID/Status LEDs (front) are green
■ SIM Power LED (back) is green
■ Power supply module LEDs (back) are green
Note – A steady amber LED on any component indicates a problem with that
component.
ESD Precautions
Observe the following electrostatic discharge (ESD) precautions:
■ Remove all plastic, vinyl, and foam material from the work area.
■ Wear an antistatic wrist strap at all times when handling any CRU.
■ Before handling any CRU, discharge any static electricity by touching a grounded
surface.
■ After removing a CRU from the cabinet, immediately place it on an antistatic mat.
■ Handle any card that is part of a CRU by its edges only and avoid touching the
components or circuitry.
■ Do not slide a CRU over any surface.
■ Limit body movement (which builds up static electricity) during the removal and
replacement of a CRU.
Removing a Chassis
Caution – You must remove power from the chassis that needs to be replaced
before starting this procedure. All interconnected trays will be disrupted during this
procedure. Powering off one J4400 Array tray causes loss of access to other
interconnected trays.
1. From the back of the cabinet, locate the chassis (also referred to as a tray) that is
being replaced (see “Verifying a Chassis Failure” on page 1).
2. Disconnect the power cord from each power supply (see
2Sun Storage J4400 Array Chassis Replacement Guide • April 2008

or SIM Link IN to
Management Host
b. Disconnect each power cord from its power supply connector (see
FIGURE 1Removing the Power Cable and Mini-SAS Cables
Connection Between
Tray 0 and Tray 1
FIGURE 1).
Caution – For products with multiple power cords, all power cords must be
disconnected to completely remove power from the system.
3. Label each mini-SAS cable connection (see
FIGURE 1) for reconnection to the
same connectors on the replacement chassis. For example, “Tray 1, SIM Link
Out to Tray 0, Host or SIM Link IN.”
4. Disconnect the labeled mini-SAS cables from each SIM board.
a. Grasp the metal body of the connector with one hand, and use your other
hand to firmly grasp and pull the tab.
b. Pull the tab gently toward the connector body, and, then with your other
hand, extract the connector from the bulkhead.
Replacing a J4400 Array Chassis3
Caution – Do not twist the tab or pull it in any direction other than parallel with
the connector body. If the tab breaks, use a small sharp object (such as a fine-tipped
screwdriver) to lift the metal spring at the top of the connector shell to unlatch it (see
FIGURE 1).
Caution – Electrical Shock Hazard. The power supplies in this equipment can
produce high energy hazards. Only instructed personnel with authorized access to
this equipment can remove and replace modules in the system.

5. Remove each SIM board from the chassis (see FIGURE 3).
Caution – Possible lose of configuration data. Label the SIM boards (SIM 0 and
SIM 1) as you remove them from the faulty chassis, and reinstall them in the new
chassis in the same slot order to prevent possible loss of driver configuration data.
a. Loosen the captive thumb screws on the ejection levers and pull the
ejections levers out fully to partially eject the SIM board from the tray.
b. Pull the SIM board from chassis (see
FIGURE 3).

6. From the front of the cabinet, remove each disk drive and disk filler assembly
(see
FIGURE 4).
Caution – Potential loss of data access - Data might be lost if an active disk drive
is removed. If you remove an active disk drive accidentally, wait at least 30 seconds
before reinserting it.
Caution – Potential loss of configuration information or data - Label each disk
drive with the slot from which it was removed, and reinstall each drive in the
identical slot location in the replacement chassis.
a. Press the release button in and to the right to release the disk extraction
lever.
b. Swing the extraction lever fully out and to the right to partially extract the
disk drive from the tray.
c. Grasp the middle of the disk drive and pull it toward you to remove it from
the tray (see

d. Record the slot location on the outer drive casing. Use the same slot location
when installing each disk drive in the new chassis.
e. Store each disk drive in a static-free environment.
7. After you have removed all of the components from the chassis, remove the
chassis from the cabinet (see
FIGURE 6).
Caution – The empty weight of a chassis is 14 kg (32 lbs). You might need two
people to remove the chassis from the cabinet.
a. Remove the two system locking clips from the lower corners of the rear
chassis (see ). You can use a Phillips head screwdriver for leverage to help
you pull out each clip. Set the clips aside.
