other fans increase their speed to provide sufficient cooling. The hot-pluggable fans are performance monitored by the SPCN (see “System Power Control Network (SPCN)” on page 15). The hot-swappable power supplies and fans can be replaced concurrently if the optional redundant power is installed.

The dimensions of the Model F80 are 483 mm W x 728 mm D x 610 mm H (19.0” W x 28.7” D x 24.0” H). The weight is from 70 kg (155 lbs) to 95 kg (209 lbs) depending on the configuration. Unlike the Model F50, the Model F80 does not provide rollers.

The Model F80 is designed for customer setup of the machine and for subsequent addition of most features.

Figure 1 shows front/side view of a Model F80 showing the location of the major features. A discussion of these features follows.

Figure 1. Model F80 Overview

On the bottom of the chassis are three slots on the backplane used for the processor card (top slot) and the two possible memory cards (middle and bottom slots). A dummy memory card is installed in all shipped units for each unused memory slot for safety and proper machine cooling.

The following ports are provided by Model F80 as shown in Figure 2:

•One Ultra2 SCSI port for external attachment use (mini 68-pin VHDCI 1 connector)

The industry standard VHDCI 68-pin connector on the backside of the Model F80 allows attachment of various LVD and SE external subsystems. A 0.3 meter converter cable, VHDCI to P, mini-68 pin to 68-pin, (# 2118) can be used with older external SE subsystems to allow a connection to the VHDCI

connector.
