92 Servicing & Upgrading
Field Replaceable Units (FRUs)
Identifying FRUs
There are two types of field replaceable units:
■
“HP Service Personnel Only”. These units that can be serviced
only
by HP
service personnel, or by qualified service representatives. They are
designated as “HP” in Table 19 and Table 20 .
■
“Customer Replaceable Units”. These units can be serviced by a customer,
or by HP service personnel or qualified service representatives. (A
“customer” is defined as any person responsible for the administration,
operation, or management of the array.) They are designated as “CRU” in
Table 19 and Table 20 .
Note The FRU type designations also apply to upgrade kits. For
example, only HP service personnel should install an upgrade
array controller, but a customer may install an upgrade disk
drive to increase capacity.
Refer to the following figures and tables to identify FRUs in the controller
enclosure and the disk enclosure:
■
Figure 32 shows the locations of the controller enclosure FRUs and Table
19 lists their part numbers.
■
Figure 33 shows the locations of the disk enclosure FRUs and Table 20 lists
their part numbers.
Note Both DS 2400 Disk Systems and DS 2405 Disk Systems are used
as disk enclosures in the VA 7400/7410. Where necessary, the
differences in these products are identified.
An easy way of determining which type of disk system is
installed is to use the
armdsp -c
command. The Controller
Type field indicates the type of disk enclosure, DS 2400 or
DS 2405.
