2. Remove Rack Door from hinges and set aside.
2.0.0 Single SS8460 Power Down Procedure
1. Stop all I/O to the SS8460.
2. Perform a “show subsystem summary” command and note any faults (not being
corrected by the enclosure replacement), total physical disks, pool state, virtual
disk state, and disk channel count.
3. Note either the failed enclosure’s ID or all the surviving enclosures ID’s with a show
enclosure command.
4. Shutdown controllers with a “shutdown subsystem” command. This will power
down the storage controllers.
5. Power down the SS8460 by turning off the switches on the PCMs. Figure 2

2. Perform a “show subsystem summary” command and note any faults (not being
corrected by the enclosure replacement), total physical disks, pool state, virtual
disk state, and disk channel count.
3. Note either the failed enclosure’s ID or all the surviving enclosures ID’s with a
“show enclosure” command.
4. Shutdown controllers with a “shutdown subsystem” command. This will power
down the storage controllers.
5. Power down the master SS8460 by turning off the switches on the PCMs.
6. Power down the remaining e pansion enclosures by turning off the switches on
their PCMs. Figure 2
3.1 Disconnect the SS8460 from the storage controllers or
expansion enclosures.
Each SS8460 ships with two fully redundant PCMs. CAUTION: If power cable
replacement is required. Use only the power cables supplied with the enclosure.
Do NOT use another type of cord or e tension cords. If you require additional
power cables, please contact your DDN sales representative.
1. Verify that the power switch on both PCMs is in the OFF position (Figure 2).
2. Then disconnect the two power cables from rear of the SS8460. (Figure 3).

5. Use step ladders supplied with the FRU enclosure for upper rack U locations
as needed.
6. Verify that the cables and cable arm assemblies are such that cables won’t
get hung up and pulled on when the enclosure is removed.
7. Slide the enclosure out from the rack by pushing in the two release tabs on
front of the enclosure (Figure 6). Keep pulling until the enclosure locks and
you hear a clicking . The unit should now be out enough to open top covers.

8. Disconnect the SAS cables from the I/O modules. Disconnect the cable at the
highest position in the Cable Management Assembly CMA from the
innermost host port used on the I/O module (Figure 6). Then disconnect the
second cable to the ne t innermost host port used, working from the inside
toward the outside. Use Velcro to tie back in a safe place. Note that for SFA
subsystem installation, not all host ports are used on the I/O modules. Refer
to the cable maps given in the SFA OS User Guide to determine which host
ports are used

9. Remove the CMA cross bar on the rear panel of the enclosure by removing
two #10-32 screws as shown in Figure 7.
10. Repeat Step 1 above to remove the other CMA cross bar from the rack rear
panel of the enclosure.

4.0 Removal of Dis Modules and Enclosure
CAUTION : Whenever handling disc modules ensure that the disk modules are at
room temperature before installing ore removing and powering up the SS8460.
It is recommended that the disks are allowed at least two hours at installation
and thirty 30 minutes after power down to acclimate to room temperature.
Figure 8 shows the layout of disks in the SS8460. The disk layout may also be
found inside the cover of the enclosure. Refer to Appendi B for information on
zoning configuration.
1. Prepare an area such as a table located in close pro imity to the SS8460 you
are working on for placement and temporary storage of the removed disc
modules. NOTE: It is highly recommended that each disc module and blank
be labeled with its current installed location within the SS8460 prior to
removal.
2. Store the drives in an area so that they remain acclimated to room
temperature. Drives and new replacement enclosure must be acclimated to
the same room temperature before drives can be reinstalled into the
replacement enclosure.

Figure 8 . Disk Module
Layout
3. Swing up both cover release handles to disengage the locks (Figure 9). Lift
up the cover. The cover is equipped with constant torque hinges which allow
the door to remain in place at any open position and prevent it from being
dropped.
Figure 9. Cover Release Handles
When removing the disk modules:
- Create a more balanced load by evenly distributing the disk modules among the
enclosures
- Always remove the rows from back to front.
Note that disks with similar rotational speeds are placed in the same row if a
mi ture of disk technologies are populated into one enclosure, for optimal
performance, the best loading order from back to front will be:

- SAS disks, SATA disks, then SSD
- - 3.5" HDD, then 2.5" HDD or smaller
-
Note : To ensure proper airflow through the enclosure, the SS8460 requires that any
empty disk slot to be filled with a blank module.
4. On the disk module, press the latch to release the handle (Figure 10).
Figure 0. Release Latch on Disk Module
5. Carefully slide the module from the disk slot (Figure 11).
Figure . Removing Disk Modules
6. Repeat Steps 4 and 5 above to remove all the remaining disks and blank
modules.
5.0 Removal of Suspect SS8460 C assis from Current Configuration.
1. Carefully position the lift tool in front of the rack (Figure 12) and raise the load
plate up under the enclosure to be removed so that the load plate is now
supporting the enclosure. Ensure the foot brake is applied and secure in position

3. Re Use the packaging material from the new replacement unit to repack the
suspect unit for proper return.

6.0 Installation of New Replacement SS8460
6.01 Installation Overview
1. Unpack the SS8460 system.
2. Rack mount the SS8460 and install cable management assembly. Refer to
Appendi A for physical dimensions and weight of the SS8460.
3. Install the disk modules.
4. Connect the SS8460 to the storage controllers or e pansion enclosures.
5. Power up the system.
6.0.2 Unpac ing the SS8460
Your SS8460 ships with the following:
- SS8460 enclosure
- Two power cables
- Rack-mounting hardware
- Cable management hardware
- SS8460 user documentation CD
- Disk modules
- Blank modules (if ordered)
Before you unpack your SS8460, inspect the shipping containers for damage. If
you detect damage, report it to your carrier. Retain all bo es and packing
materials in case you need to store or ship the system in the future.
Perform the following steps:
1. Open the top of the bo . Inspect for damage.
2. Remove all the components from the packaging, inspect the SS8460
chassis and all components for signs of damage. If you detect any
problems, contact DataDirect Networks Customer Service as soon as

possible. Then place the components on an anti-static surface until you are
ready to use them.
3. There are two nylon lifting straps that are used to remove the enclosure
assembly from the bo (Figure 15). A forklift or other mechanical lifting
device is highly recommended to remove the unit and to place on the IBM
lift tool.
Figure 5 Unpacking the SS8460
6. If you are installing the enclosure in a rack: a) Ensure that you have these tools
available: • Phillips screwdriver • Bubble level b) Arrange for assistance during
installation c) Ensure ahead of time that you have chosen a suitable location for the
enclosure or rack assembly.
7. Ensure that the area around the enclosure or rack assembly has sufficient cooling
and space around the unit to access cabling.
8. When installing disk modules, allow them to acclimate to room temperature prior to
installation. Disks should be stored at room temperature for at least two hours prior
to use.
6.0.3 Installing the SS8460 in a Rac
The SS8460 enclosure is designed to fit within a 4U rack space. Follow these steps to
mount the enclosure in your rack:
1. Ensure that you have these rack mount components: • Rack rails (one left, one
right) • Rail installation hardware (screws, screw plates, shelf locking brackets)

2. Remove the enclosure rails from the right and left side of the enclosure. If rails
were shipped with the replacement unit you may instead, pull the enclosure rail out
of the rack rail until it is fully e tended. Then press the locking tab down to release
the enclosure rail (Figure 15a and B). Press the locking tab on the middle rail and
push it back into the rack rail. Repeat for the other rack rail.

3. Attach the enclosure rails to each side of chassis by positioning the rails
over the keyhole tabs, and slide the rails into place. The rails are marked
“R” (right) and “L” (left) viewing from the front of the enclosure. Do not
e change the enclosure rails. Secure each rail using seven #8-32 flat head
screws (Figure 15b).
4. With the new replacement SS8460 in place on the lift tool carefully position
the lift tool in front of the rack (Figure 12) and raise the load plate up under
the enclosure to be removed so that the load plate is now supporting the
enclosure. Ensure the foot brake is applied and secure in position Figure
13.
5. Position the lift tool shelf and new replacement SS846 to the proper height
to enable alignment of enclosure rails and rack rails and slide the rear
alignment blocks on to the rack rails to align the enclosure properly with the
rack rails.
6. Carefully engage the enclosure rails into the rack rails and slide the
enclosure in until the enclosure rail tabs “click” into place. The SS8460
enclosure is now mounted in the rack (Figure 16).
Figure 6. Enclosure installed in Rack
7. Carefully reinstall all drives removed in previous steps by sliding the module
into a disk slot until it contacts the baseboard and begins to engage the
handle (Figure 11). Press down on the handle until it latches which will cam
the module into place.
8. Reconnect the SAS cables, CMA cross bars.
9. Verify that the power switch on both PCMs is in the OFF position Figure 2.

10. Reinstall Power cables removed in previous steps. Figure 3.
6.0.4 Single SS8460 Power up Procedure
1. Turn the switch on each PCM to the ON position.
2. Wait appro imately 1 minute for all the disks to become ready.
3. Power on and boot the storage controllers.
4. Verify and set zoning if necessary
a. Note lines 11 and 12 from the output of “show enclosure X all”
where X is inde of the replacement enclosure
b. For 1-5 shelf configurations, the zoning should be:
i. Zones: 2
ii. Zoning Configuration: 1
c. For ten or greater shelf configurations the zoning should be:
i. Zones: 1
ii. Zoning Configuration: 0
d. If the enclosure zoning is incorrect (normally set by the factory with
one zone) then issues the following commands against the
enclosure:
i. “Set enclosure X zoning Y” (where X is enclosure inde and
Y is 0 or 1)
ii. “Set enclosure X restart” (see inde from previous step)
iii. Issue “show enclosure + 60”. Wait until response is TRUE,
and then hit return to stop the output.
iv. Show enclosure X all (verify zoning change took affect)
5. Perform a show subsystem summary command and note any faults (not
being corrected by the enclosure replacement), total physical disks, pool
state, virtual disk state, and disk channel count.
6.0.5 Multiple SS8460 Power up Procedure
CAUTION : The power up order is critical for each of the e pansion enclosures
to properly be seen by the previous unit in the chain. For systems with
e pansion enclosures attached, the enclosure last in the chain should be
powered up first, followed by the other enclosures with the master unit being
turned on last.
1. Turn the switch on each PCM supply to the ON position.
2. Wait appro imately 1 minute for all the disks to become ready.
3. Power on and boot the storage controllers.
4. Verify and set zoning if necessary
a. Note lines 11 and 12 from the output of “show enclosure X all”
where X is inde of the replacement enclosure
b. For 1-5 shelf configurations the zoning should be:
i. Zones: 2
ii. Zoning Configuration: 1
c. For ten or greater shelf configurations the zoning should be:
i. Zones: 1
ii. Zoning Configuration: 0
