2280 balanced model (2280 for short) of the TaiShan 200 server, 1288H V5, and RH1288 V3
can be used as quorum servers. If you want to replace a component such as a VGA board,
indicator board, or disk backplane in a quorum server, see Removal and Installation in the
Maintenance and Service Guide specific to your product.
When two power modules are configured, remove one power module without
powering off the quorum server if the other power module is operating
properly and its power rating is greater than or equal to the rated power of
the quorum server.
You have determined the position on the quorum server for removing a power
module.
You have obtained the cabinet number and chassis number of the quorum
server.
You have located the quorum server based on the preceding information, and
labeled its panel to prevent misoperations.
