APC Cable, UPS Communications Smart Signalling (15' / 4.5m - DB-9 to DB-9 Serial)

Product Overview

AI-generated summary

For the right customer, this APC DB‑9 serial signalling lead is fine—simple, purpose-built, and usually the missing piece when an existing UPS management setup just won’t talk. £41 ex‑VAT isn’t “cheap”, but for B2B it’s often a reasonable price because you’re not buying power hardware, you’re buying the ability to integrate with your monitoring/management software without faffing about with adapters and converters that may never work reliably. If you’ve got an APC UPS with serial monitoring requirements, and your existing cable is missing, broken, or too short, this will get you back to scheduled status alerts and clean monitoring quickly.

I’d only buy it if you’re sure you need serial signalling specifically—don’t assume it’s interchangeable with USB or newer network monitoring. Also, if your environment is moving toward SNMP/network management, spending this kind of money on a serial cable may be a step backwards. For someone building out a small rack, server room, or a single management workstation for older APC UPS monitoring, it’s a sensible “make it work” purchase; for anyone modernising monitoring, it’s probably better to look at the UPS options that support network management so you don’t keep chasing legacy connectivity.
