The 9H532-24, 9H533-24, 9H531-24, and 9H539-24
Modules
Each module is a 24-port switching module:
•
9H532-24 – 24 10Base-T/100Base-TX ports (RJ45 connectors)
•
9H533-24 – 24 10/100 Ethernet ports (two RJ21 Telco connectors)
•
9H531-24 – 24 100Base-FX ports, multimode fiber (mini MTRJ transceivers)
•
9H539-24 – 24 100Base-FX single mode fiber ports via mini MTRJ transceivers
Each module can operate in either full duplex or half duplex mode. 100Base-FX
supports 100 Mbps speed at both half and full duplex.
Auto-negotiation (available only with the 9H532-24 and 9H533-24 modules)
provides support for 10 Mbps and 100 Mbps speeds at both half and full duplex.
This feature allows the module to automatically use the fastest rate supported by
the device at the other end (either 10 Mbps or 100 Mbps at either half or full
duplex). To negotiate duplex, both the 9H532-24/9H533-24 and the attached
device must be configured for auto-negotiation. If only the 9H532-24/9H533-24 is
configured for auto-negotiation, the module will set the connection to half duplex
at either the 10 Mbps or 100 Mbps rate. This technology is similar to how modems
negotiate transmission speed, finding the highest transmission rate possible.
Similarly, auto-negotiation determines the highest common speed between two
devices and communicates at that speed. If no common speed is detected, the
device will be partitioned.
Module Interface Codes
