Questions & Answers
What is the CR52-P20-12x10/100/1000Base-TX-RJ45 Flexible Card?
The CR52-P20 is a 12-port network interface card offering 10/100/1000 Mbps RJ45 connectivity, designed for high-density switching platforms.
How many ports does the CR52-P20 card provide?
The card provides 12 independent 10/100/1000 Mbps RJ45 ports for copper Ethernet connections.
What speeds are supported on each port?
Each RJ45 port auto-negotiates speeds of 10 Mbps, 100 Mbps, or 1000 Mbps to match connected devices.
Which switch chassis models support the CR52-P20 card?
The CR52-P20 is compatible with CR52-series and P20-series modular switch chassis from the same vendor.
Can I install the CR52-P20 card without powering down the switch?
Yes. The CR52-P20 supports hot-swapping, allowing installation or replacement with minimal network disruption.
What type of cabling is required for the RJ45 ports?
Use Category 5e or higher UTP/STP copper cables terminated in standard 8-pin RJ45 connectors.
Does the CR52-P20 support auto-MDI/MDI-X crossing?
Yes. Auto-MDI/MDI-X eliminates crossover cables by automatically detecting and correcting pinouts.
Is Power over Ethernet (PoE) supported on these ports?
No. The CR52-P20 is data-only and does not provide PoE functionality.
What is the maximum cable length per port?
Each port supports up to 100 meters of copper cabling (Cat 5e or better) at 1 Gbps.
Does the card support jumbo frames?
Yes. It supports jumbo frames up to 9,216 bytes for improved data-throughput efficiency.
What are the power consumption characteristics?
Typical power draw is 8 W, with a maximum of 12 W under full load across all ports.
Which Layer 2 features are supported?
The card supports VLAN tagging (802.1Q), link aggregation (LACP 802.3ad), IGMP snooping, and STP/RSTP.
Can I aggregate multiple ports for higher throughput?
Yes. Up to eight ports can be bundled via LACP to increase bandwidth and provide redundancy.
What operating temperature range is supported?
The card operates reliably between 0 °C and 45 °C (32 °F–113 °F) in standard data-center environments.
What warranty and technical support are included?
The CR52-P20 includes a limited lifetime hardware warranty and 24/7 global technical support via phone and online portal.
How do I monitor port status and traffic?
Use the switch’s built-in management interface (CLI, SNMP, or web GUI) to view link status, traffic counters, and error statistics per port.
