Cisco ASA5516-X Series Firewalls - Refurbished, Used, New

Best Selling

The Cisco ASA 5516-X is a 1U rack-mount firewall with eight 1G RJ45 data ports and 1.8 Gbps of stateful inspection throughput, sized for a branch office, a small campus edge or an internet edge at a mid-size site. It runs either classic ASA software or Firepower Threat Defense (FTD), so it fits a shop that still manages firewalls with ASDM and the ASA CLI as well as one that has moved to Firepower Management Center. This collection covers the two appliance versions, ASA5516-FPWR-K9 and ASA5516-FTD-K9, the 120 GB mSATA SSD the FirePOWER and FTD images run from, and the rack mount bracket kit. NetworkTigers sells ASA 5516-X firewalls and parts refurbished, used and new, and every unit is tested before it ships so it works when it arrives.

Which ASA 5516-X do I need?

The two appliance part numbers are the same box; the suffix tells you which software image it was ordered with. Choose ASA5516-FPWR-K9 if you run ASA software with ASDM or the CLI and want the FirePOWER services module available for inspection, or ASA5516-FTD-K9 if you manage the firewall as an FTD device from Firepower Management Center or Firepower Device Manager. Either unit can be reimaged to the other software, so the decision is about which image you want installed when it arrives, not about hardware. Check the SSD: FirePOWER services and FTD both need the mSATA drive installed, and a unit sold without one needs an ASA5516-SSD before those features will run. Check the bracket: the appliance ships from Cisco as a 1U unit with rack ears in the box, but used units often arrive without them, and the ASA5516-BRACKET kit fixes that. If you are pairing a new unit with an existing 5516-X for failover, match the software version on both. Units listed as "No Clock Issue" are from hardware revisions not affected by the clock signal component fault seen on some early units.

Frequently asked questions

Does the ASA 5516-X have a separate management port?
Yes. In addition to the eight data ports there is a dedicated management Ethernet port, a console port and USB. On FTD the management port is how Firepower Management Center reaches the device, so plan a management VLAN or out-of-band network for it.

Can two ASA 5516-X units run in an active/standby pair?
Yes. Both ASA and FTD software support high availability between two 5516-X appliances connected by a dedicated failover link. The two units must run the same software version and have the same SSD and interface configuration.

What does "w/ FirePWR" or "w/ FTD" in a listing title mean?
It tells you which image the unit was ordered or tested with: FirePOWER services alongside ASA software, or the FTD image. It describes the software on the box, not any subscription or support entitlement, which is arranged separately with Cisco.
