7Replacing the chassis
The 4/256 SAN Director chassis is highly reliable and unlikely to fail. This chapter describes how to
remove and replace a chassis in the event of a failure.
Refer to the following sections of this chapter for specific information:
• Replacing the chassis — items required, page 160
• How to determine whether or not to replace the chassis, page 160
• Record critical switch and SAN information, page 160
• Disconnect from network and fabric, page 166

• Remove and replace chassis, page 167
• Install components into new chassis, page 168
• Install modems (optional), page 169
• Verify correct operation of hardware, page 169

• Verify correct operation of system, page 171
• Reconnect system to network and fabric, page 173
• Verify correct configuration of fabric, page 174
• Cable routing table, page 176
The 4/256 SAN Director must be removed from the fabric and powered off to perform this
procedure. Contact HP Technical Support if you have any questions about whether the chassis
requires replacement.
CAUTION: Inform your SAN administrator that the 4/256 SAN Director must be disconnected
from the fabric for the duration of the mechanical replacement and that root login is required.
If the switch is installed in a cabinet, ensure that the cabinet is balanced and secured mechanically
and that the removal and installation procedure will not compromise cabinet stability.
Disassembling any part of the chassis voids the part warranty and regulatory certifications. The
chassis itself contains no user-serviceable parts.
