1.5 Sx300 Storage Array Site Preparation

The Sx300 storage array is intended for installation in a Class A computer

room environment that meets the conditions speciﬁed in Table 1–7.

Before installing the Sx300 storage array, make sure the following conditions

are met:

• The Sx300 storage array requires 1-phase ac power. The phase draws up

to 12 amperes (230 Vac) or up to 24 amperes (120 Vac) in a fully conﬁgured

array.

• Adequate space is provided around the storage array for access to front and

rear, for accessing cables at the rear of the storage array, and for adequate

airﬂow.

• The installation site ﬂoor can safely bear the weight of the storage array. A

fully conﬁgured storage array weighs up to 330 kilograms.

• The correct NEMA plug or IEC plug is available. See Figure 3–11.

• The following is only valid for DSSI:

The system’s conﬁguration sheet has been correctly ﬁlled out and is up-

to-date. Blank system conﬁguration sheets can be found in Figure 1–3,

Figure 1–4, and Figure 1–5.

An adequate number of KFMSA modules exist in the extended memory

interconnect (XMI

™

) backplane of the VAX system to support all

the disk integrated storage elements (ISEs) in the Sx300 storage

array. Refer to the KFMSA Module Installation and User Manual

(EK–KFMSA–IM) for more details.
