Replacement Procedures for Model 2200 Enclosure Elements
CAUTION: Wait for FRUTIL to quiesce the device ports—indicated by an “All device
ports quiesced” message. Failure to allow the ports to quiesce might result in data
loss. Quiescing might take several minutes.
IMPORTANT: A countdown timer allows a total of 2 minutes to remove the cache module.
After 2 minutes, “this controller” exits FRUTIL and resumes operations. If this happens,
return to step 5 and proceed.
8. Remove the cache module:
a.
Disengage both retaining levers and remove the “other controller” cache
module.
b.
Place the cache module on a grounded antistatic mat or in an antistatic bag.
9. Is a replacement cache module available now?
•
No. Enter N(o) and disconnect the PC or terminal from the controller
maintenance port.
FRUTIL will exit.
NOTE: If reverting to a single-controller configuration, fill the vacant cache module bay
with a blank bezel to prevent the enclosure from developing a potential
over-temperature condition.
•
Yes. Use the following steps to remove the DIMMs from the cache module for
installation in the replacement cache module.
a.
Press down on the DIMM retaining clips
3
at both ends of the DIMM
1
being removed (see Figure 4–5).
NOTE: To make pressing down on the DIMM retaining clips easier, use the eraser
end of a pencil or a small screwdriver.
b.
Gently remove the DIMM from the DIMM slot
2
and place the DIMM in
an antistatic bag or on a grounded antistatic mat.
c.
Repeat step a and step b for each DIMM.
d. Insert each DIMM
1
straight into the appropriate slot
2
of the
replacement cache module, ensuring that the notches in the DIMM align
with the tabs in the slot (see Figure 4–5).
e.
Press the DIMM gently into the slot until seated at both ends.
f.
Engage the two retaining clips
3
for the DIMM.
