Procedure 12-15 (continued)
Replacing the equipment fan shelves
Equipment fan shelf types
The type of equipment fan shelf or shelves used in the S800A cabinet depends
upon whether the cabinet is a standard (NT1W00DA/EA/FA) or VTBM-ready
(NT1W00GA/HA/JA) cabinet. Standard S800A cabinets use the same
NT1W09AA fan shelf in both the standard (Fan shelf 2) and optional (Fan
shelf 1) locations. VTBM-ready S800A cabinets use an NT4K0610 fan shelf
in the standard (Fan shelf 2) location and an NT1W09CA shelf in the optional
(Fan shelf 1) location.
Table 12-13 presents the standard and optional equipment fan shelf types used
in the standard and VTBM-ready S800A cabinets.
