Note:
The SAN384B must be removed from the fabric and powered off to perform
this procedure. Contact IBM Support if you have any questions about
whether the chassis requires replacement.
Time required
The chassis replacement takes approximately 3 hours.
Items required
The following items are required for the chassis replacement:
v
ESD grounding strap
v
ESD grounding pads for protecting all blades and WWN cards
v
Serial cable and workstation computer with a terminal emulator application
(such as HyperTerminal for Windows systems or TIP for UNIX systems),
required only if serial console session used
v
Hydraulic lift (see “Ordering the lift tool” on page 11) that raises a minimum of
140 cm (55 in.) and carries a minimum of 113 kg (250 lb)
v
A surface to place the old chassis on, such as a second lift or the pallet originally
provided with the old chassis
v
#2 Phillips screwdriver
Verifying need for replacement
Verify that replacement of the chassis is necessary. Ensure that the components are
firmly seated when troubleshooting, and contact IBM support with any questions
about whether the chassis should be replaced. Any of the following events might
indicate the need to replace the chassis:
v
Visible mechanical damage to the chassis, including damage to sheet metal or
card guides that prevents correct installation of a blade.
v
Bent or damaged connectors on the backplane (the surface inside the chassis to
which the blades connect).
v
One or more components (such as a power supply, blower assembly, port blade,
control processor blade (CP8), core switch blade (CR4S-8), or WWN card) do not
function properly even after the component was replaced.
v
The
psShow
or
fanShow
commands continue to show a faulty component even
though the component was replaced.
v
The
slotShow
command continues to show a faulty control processor (CP8), core
switch (CR4S-8), or port blade even though the blade was replaced.
Recording critical SAN384B and SAN information
All commands must be entered from a CLI session (Telnet or serial) to the active
CP blade unless otherwise indicated.
