Chapter 2 Setting Up Share-UPS

Installing Multiple Accessories

Introduction	If your UPS configuration uses more than one APC acces-
	sory, you must install them in the correct order for them to
	work together properly. Connect the Share-UPS unit to the
	Computer Interface port of the UPS, installing only a Mea-
	sure-UPS II device in a SmartSlot accessory slot of the UPS.
	Install all accessories according to priority, referring to “Pri-
	ority of APC accessories: Table 4,” on page 16.
	Note: SmartSlot accessories fit into APC UPSs and acces-
	sories equipped with a SmartSlot accessory slot.
	External accessories connect to the Computer Inter-
	face port of the UPS or to the Advanced port of other
	APC accessories (including Share-UPS).
Multiple	If you need more than the eight ports available with
Share-UPS units	Share-UPS, you can daisy-chain up to 5 Share-UPS units
	together, provided that the total number of accessories
	(including Share-UPS units and APC’s PowerView™) does
	not exceed 10.
	Note: When daisy-chaining Share-UPS units, you may need
	to use a power adapter (see “Optional Power input,”
	on page 9). You may also need to lengthen the timeout
	delay in PowerChute plus by editing the [ ups ] sec-
	tion of pwrchute.ini to include “TimeoutFactor = 100”
	(or greater) to keep the software from interrupting the
	daisy chain’s communications.
	Each added Share-UPS unit provides seven more Basic
	ports. Only one Advanced port in the daisy chain is avail-
	able for connection to the master server. For connection
	instructions, see step 2 of “Connection procedure” on page
	21.
