Installing an Add-On Disk Module Array
73
Caution:
Use only CHALLENGE RAID disk modules as replacements; only
they contain the correct device firmware. Other disk modules, even those
from other Silicon Graphics equipment, will not work. Do not mix disk
modules of different capacities within one array. Do not remove disk
modules from bus 0 (slots A0, B0, C0, D0, and E0) for use in other disk
module positions.
Installing Add-On Disk Modules
Follow these steps:
Caution:
Leave the filler modules installed until the add-on replacement
modules are available. Never remove more than one disk module or disk
filler module at a time.
1.
Read “Setting Up the Workplace for Replacing or Installing Disk
Modules,” earlier in this chapter.
2.
Position the new disk modules in their antistatic packaging within
reach of the storage system.
3.
If you are using a wrist band, attach its clip to the ESD bracket on the
bottom of the storage system, as shown in Figure 5-3. Put the wrist
band around your wrist with the metal button against your skin.
4.
Locate the slots where you will install the add-on disk modules; see
Figure 5-2.
Warning:
Although you need not complete each chassis assembly
that is partially filled before installing more disk modules in the next
chassis assembly, avoid making the rack top-heavy.
Fill the slots in this order:
•
first, in this order: A0, B0, C0, D0, E0
•
next, in this order: A1, B1, C1, D1, E1
•
next, in this order: A2, B2, C2, D2, E2
•
next, in this order: A3, B3, C3, D3, E3
5.
Grasp the filler module for the first slot and pull it out of the cabinet; set
it aside for possible future use. If you cannot grasp the module, use a
medium-size flat-blade screwdriver to pry it out gently.
