3.2 Laser Expander Cabinet

Refer to Figure 3, Laser Expander Cabinet Layout

The expander cabinet is the same as the system cabinet without the CPU bits. It has no

LSB card cage or OCP. In place of the LSB card cage, 2 more PIUs can be installed. Due to

weight and cabling restrictions these can only be storage PIUs. A TF85 or RRD42 may be

ﬁtted as in the system cabinet. A maximum of 2 expander cabinets is allowed.
