*1: Perform maintenance work using PCI hot plug (PHP). See "13.3 CheckingIf PCI Hot Plug (PHP) Can Be Used" to check whether
PHPcan be used.
IfSE0X7SA2F (an SAS card) is used, PCIe card release using PHP may fail. If therelease fails, perform inactive replacement.
*2: It is necessar yt ou se dynamic reconfiguration (DR) for the physical partition to disconnect a chassis requiring ma intenance from the
physicalpartition.
*3: For a single -chassis configuration, system-stopped maintenance should be performed.
13.2 Before Maintaining a PCI ExpressCard
Thissectio n describes the types and the flow of the maintenance of the PCIe cards, as
wellas some precautions.

13.2.1 Typesof maintenance

Table13-1 lists the types of maintenance for the PCIe cards. For the definition of
maintenance,see "4.3 Understanding Types of Maintenance."
TheP CIe cards can be removed/installed while the input power to the chassis is on
(powercord is connected).
Thissectio n explains how to perform all types of maintenance work while the power
cordof the chassis remains connected.

13.2.2 Maintenanceflow

Table13-2 lists the sequence of the maintenance procedure for PCIe cards. The
procedure for expanding a PCIe card is the same as that for installing a PCIe card.
Thepr ocedure for reducing a PCIe card is the same as that for removing a PCIe card.
