Avaya AL3518001-E6 Ethernet Routing Switch Stack Cable

Avaya AL3518001-E6 Ethernet Routing Switch Stack Cable is a 46 cm SFP-direct-connect cascade cable used to link Avaya ERS 3500 switches into a single stacked system. Designed for the ERS 3500 family, it connects cascade ports on compatible models such as the ERS 3510GT and ERS 3524GT to enable synchronized operation across the stack. Stacking cables are sold separately from the switches, and this particular part is one of several AL351800x-E6 options intended for different installation layouts. In addition to the 46 cm AL3518001-E6, Avaya offers AL3518002-E6 (1.5 m) and AL3518003-E6 (3 m) in the same family to accommodate varying rack depths and cabinet configurations. This cable is a standard component in Avaya's ERS 3500 stacking ecosystem and is commonly referenced in official installation guides as the recommended cascade cable for establishing a multi-switch ERS 3500 stack. According to Avaya installation guides, stacking cables are not included with the base switch and must be ordered separately.
