100BASE-TX Network
When connecting a 100BASE‐TX segment to one of the fixed ports (1 through 24 on A2H124‐24P, 1 through 48 on A2H124‐48P) use Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 100BASE‐TX Fast Ethernet network requirements for the SecureStack A2 to operate at 100 Mbps.
Note: When using the RJ45 ports on the SecureStack A2 for 100 Mbps operation use
Category 5 UTP cabling with an impedance between 85 and 111 ohms.
The fixed SecureStack A2 ports are capable of operating at 10 and 100 Mbps. This is accomplished by the SecureStack A2 when
1000BASE-FX Network
The Mini‐GBIC port sockets (27 and 28 on A2H124‐24P; 51 and 52 on A2H124‐48P) enable you to vary the type of 1‐Gbps port connection. At the printing of this document there were six supported Mini‐GBICs available, as follows:
•MGBIC‐LC01 for a 1000BASE‐SX compliant LC fiber‐optic multimode connection
•MGBIC‐LC03 for a 1000BASE‐SX Long Haul LC fiber‐optic multimode connection
•MGBIC‐LC09 for a 1000BASE‐LX compliant LC fiber‐optic single‐mode connection
•MGBIC‐MT01 for a 1000BASE‐SX compliant MT‐RJ fiber‐optic single‐mode connection
•MGBIC‐08 for a 1000BASE‐ELX compliant LC fiber‐optic single‐mode connection
•MCBIC‐02 for a 1000BASE‐T compliant RJ45 copper connection
The device at the other end of the fiber connection must meet the same Gigabit Ethernet requirements for the connected devices to operate at 1‐Gigabit speed.
1000BASE-T Network
The RJ45 fixed front panel stacking port connectors support RJ45 copper 1000BASE‐T compliant connections. When connecting a 1000BASE‐T segment to one of the RJ45 fixed ports use Category 5 UTP cabling. In standalone mode, the stack ports may be user configured to serve as a standard switch port, allowing Gigabit uplink to the network. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 1000BASE‐T Gigabit Ethernet network requirements for the devices to operate at
1000 Mbps.
