Cable, CompactFlash and Accessory Specifications

GigabitEthernet Ports

The XSR comes equipped with three GigabitEthernet (LAN) ports that support full-duplex 10, 100, or 1000 Mbps transmission. The ports conform to IEEE 802.3 standards with 8-pin modular RJ-45 connectors. Because these ports have internal MDI crossover capabilities which allow them to detect which mode (DTE or DCE) the link partner is operating at, you can use any cable to attach the XSR with a PC or uplink port as long as a fully populated cable (all four pairs) is connected to take advantage of full gigabit bandwidth.

When GigabitEthernet interface 1 is used, the Mini-GBIC port is unavailable, and vice versa.

Mini-GBIC Fiber, Copper Port

The XSR offers a 1000Base-T GigabitEthernet port that supports full or half-duplex 1000 Mbps transmission. The 20-pin, Mini-GBIC socket accepts all SFP MSA compliant Mini-GBIC modules.

Be aware of the following conditions when using Fiber or Copper ports:

When the Mini-GBIC port is used, GigabitEthernet port 1 is disabled.

When GigabitEthernet port 1 is used, the Mini-GBIC port is disabled.

If both Fiber and Copper ports are plugged in, only Fiber is enabled.

On GigabitEthernet port 1, when the far end of the line is active, the Fiber port takes precedence.

If the Fiber port is connected, speed must be set to auto to achieve 1000 Mbits.

If the fiber port is connected, speed and duplex must be set to auto on both ends of the line otherwise the connection will be unpredictable.

Refer to the XSR CLI Reference Guide for more command details.

Cabling for the Mini- GBIC is supported using an MT-RJ connector with a fiber link or the appropriate connector with a copper link.
