05 / FREQUENTLY ASKED QUESTIONS
Technical FAQ
❔ Q1. What is the difference between the 100BASE-FX MTRJ ports and mini-GBIC slots on A2H124-24FX P0973BJ?
↳ A: The 24 fixed MTRJ interfaces provide 100 Mbps Fast Ethernet fiber connectivity. The two mini-GBIC slots provide modular expansion options, subject to compatible transceiver selection.
❔ Q2. Can the RJ45 ports on A2H124-24FX P0973BJ be used as uplinks?
↳ A: The two 10/100/1000 Mbps RJ45 ports support uplink or stacking roles. Their actual configuration should match the network topology and switch settings.
❔ Q3. What should be checked before replacing A2H124-24FX P0973BJ?
↳ A: Check MTRJ fiber connections, port count, mini-GBIC requirements, RJ45 uplink arrangement, power input and the existing network configuration. Confirm the product label as well.
❔ Q4. Does A2H124-24FX P0973BJ support Power over Ethernet?
↳ A: PoE is not specified for this model. It should be selected as a fiber-oriented Ethernet switch rather than a PoE access switch.
❔ Q5. How many switches can be connected in an A2H124-24FX P0973BJ stack?
↳ A: The A2 switch family supports a stack of up to eight switches. Confirm the intended stack arrangement and port configuration before expanding an existing installation.
