Precautions specific to the blade
This document describes how to remove and replace a control processor (CP)
blade. Each device has two CPX6 blades located in slots 1 and 2.
Observe the following precautions when replacing these blades:
v The CPX6 blade is compatible only with the SAN512B-6.
v Wear an appropriately grounded ESD wrist strap when handling and installing
blades and cards. Follow electrostatic discharge (ESD) precautions. Wear a wrist
grounding strap connected to chassis ground (if the chassis is plugged in) or a
bench ground.
v Install CPX6 blades in slots 1 and 2, which are half the height of other slots in
the device.
v The firmware upgrade policy for CP blades specifies testing for the current
Fabric OS release and one version earlier. It is possible to upgrade by more than
one version, but it is a very specific and detailed process. Read the directions
under “Downloading firmware from USB device” on page 139 and
“Downloading firmware from FTP server” on page 138 carefully.
v If the new CP blade does not have the same firmware as the active CP blade, the
new blade must be upgraded to the same firmware version. After installing the
new blade, you can determine the firmware version on the replacement blade
and use the
firmwaresync
command to allow the active CP blade to copy current
firmware to the replaced standby CP blade, if necessary. However, you must
disable high availability (HA) before inserting the new blade.
CAUTION:
For safety reasons, the ESD wrist strap should contain a series 1
megaohm resistor.
CAUTION:
If you do not install a module or a power supply in a slot, you must
keep the slot filler panel in place. If you run the chassis with an
uncovered slot, the system will overheat.
CAUTION:
Static electricity can damage the chassis and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
CAUTION:
Before plugging a cable into any port, be sure to discharge the voltage
stored on the cable by touching the electrical contacts to ground
surface.
CAUTION:
To avoid damaging blade and chassis, do not use ejector handles to
push the blade into or pull the blade out from a slot.
Blade fault indicators
Confirm that you need to replace the CP blade. The following events may indicate
that a CP blade is faulty:
