Link Controller Cards (Lccs) - HP StorageWorks 7110 - Virtual Array Service Manual

Link Controller Cards (LCCs)

Caution The LCC can be damaged by electrostatic discharge. Use the
ESD kit provided when removing and installing an LCC.
The DS 2400 Disk System and the DS 2405 Disk System use
different LCCs. Do not mix LCCs in the same disk enclosure.
To prevent data loss, it is recommended that a full backup be
performed before removing an LCC.
Do not operate the disk enclosure for more than 5 minutes with
an LCC removed. An LCC must be installed in the slot to maintain
proper airflow in the enclosure. If necessary, use the foam in the
replacement LCC packaging to temporarily fill the slot.
