Servicing and Upgrading a CX200-Series DPE2
the disks it controls. You should not remove a faulty FRU until you
have a replacement available.
Since you can replace or add any FRU without sliding the enclosure
out of the cabinet, you do not have to use cabinet anti-tip devices
when you upgrade or service a CX200-Series DPE2.
If you need to power down a CX200-Series system, first shut down
the storage processors (refer to your Navisphere Manager
Administrator’s Guide), and then shut off power to the SPS, if you
have one. Shut off power to the power/cooling module(s) with the
power switch. You do not need to shut down main ac lines to the disk
enclosure unless you need to power down all the cabinet contents
connected to that line.
CAUTION
!
Never shut off the power supplies to shut down a CX200 power
supply that is connected to an SPS. Bypassing the SPS in that
manner prevents the system from saving write cache data to the
vault drives, and results in data loss. You will lose access to data,
and the storage processor event log will display an error message
similar to the following:
Enclosure 0 Disk 5 0x90a (Can’t Assign - Cache Dirty) 0
0xafb40 0x14362c
.
Contact your service provider if this situation occurs.
Avoiding
Electrostatic
Discharge (ESD)
Damage
When you replace or install FRUs, you can inadvertently damage the
sensitive electronic circuits in the equipment by simply touching
them. Electrostatic charge that has accumulated on your body
discharges through the circuits. If the air in the work area is very dry,
running a humidifier in the work area will help decrease the risk of
ESD damage. You must follow the procedures below to prevent
damage to the equipment.
Read and understand the following instructions:
◆
Provide enough room to work on the equipment. Clear the work
site of any unnecessary materials or materials that naturally build
up electrostatic charge, such as foam packaging, foam cups,
cellophane wrappers, and similar items.
