Cabletron Systems TRXI-42, TRXI-22, TRXI-24 Installation Connecting the Trxi to the Power Source

INSTALLATION

3.6CONNECTING THE TRXI TO THE POWER SOURCE

Note: The TRXI has a universal power supply. This allows you to connect the TRXI to power sources from 85 Vac to 264 Vac, 47-63 Hz.

To connect the TRXI to the power source, plug the power cord into a grounded wall outlet. Turn on the power switch at the back panel of the TRXI. Verify that the PWR LED is lit, indicating that the TRXI is receiving power. After the TRXI runs a self test, the CPU LED blinks green indicating normal operation. If the LED remains red, the processor is faulty.

3.7CONNECTING THE NETWORK LOBE PORT CABLING

The TRXI-22/24 network lobe ports consist of unshielded RJ45 connectors that support UTP cabling. To connect a UTP segment from the TRXI to a station supporting STP cabling, you need a Type 3 Media Filter available from Cabletron Systems (TRMF, TRMF-2).

The TRXI-42/44 network lobe ports consist of shielded RJ45 connectors that support STP cabling. Shielded patch cables that adapt a shielded RJ45 to a data connector (MIC) are available from Cabletron Systems (PN 9372057-8). These adapter/patch cables let you connect to an existing patch panel equipped with data connectors. Figure 3-8 shows the TRXI’s network lobe port pinouts.
