Expansion shelves
The standard documentation supplied with field replacement parts for the expansion shelves provides all
the required details, with the following important exception.
IMPORTANT:
The following parts are not hot-pluggable. The system must be taken offline before replacing them.
•
I/O module (controller board)
•
SAS cable from RAID controller card to the first expansion shelf
•
SAS cable between expansion shelves
NOTE:
Before replacing any I/O modules or SAS cables thoroughly check that all cables are fully seated and
connected. Refer also to the instructions supplied with the I/O module and to the illustrations showing
SAS cabling, as follows:
•
Storage shelves with HPE StoreOnce 4700 Backup on page 48
•
Storage shelves with HPE StoreOnce 4500 Backup on page 50
After replacing a component
Use the StoreOnce GUI or StoreOnce CLI to check that the firmware on the new component is correct.
See Upgrading BIOS or hardware firmware components on page 16.
NOTE: The system reboots after a firmware upgrade, but for some components a cold reboot is required
to complete the process. A message is displayed after the reboot if a cold reboot is also required. Power
down the system, wait the time recommended in the message and then power on again using the Power
On button.
Storage shelves with HPE StoreOnce 4700 Backup
You must install the first 24TB disk enclosure when you install the server unit. Be sure to connect the
enclosure to the correct RAID card. (See the installation and configuration .) Either at the same time or
later you may install up to seven additional 24TB capacity expansion enclosures (HPE StoreOnce
4500/4700 24TB Capacity Kit [BB881A]).
Expansion enclosures are daisy chained to the two RAID cards. HP recommends making a record of
which enclosure (serial number) is connected to which RAID card for future reference.
NOTE: The packaging and identification labels for the first storage enclosure have the same part number
as the server, BB879A. (They do not carry the HPE StoreOnce 4500/4700 24TB Capacity Kit part number
BB881A.)
The following example illustrates the first storage shelf (bottom unit) cabled to an HPE StoreOnce 4700
Backup (top unit).
