The Perle IOLAN SCG R/U Console Servers provide data center managers with secure remote console management of any device with an RS232 RJ45 or USB console port. With an expandable modular hardware platform, advanced security features, and built-in redundancy features, your IT professionals and network operations center (NOC) personnel will have everything they needed to easily perform secure remote data center management and out-of-band management of IT assets from anywhere in the world. The unique design also provides users with a flexible, cost-effective solution to transmit data from mission critical equipment over Copper or Fiber based Ethernet networks.

Modular Hardware Platform enables Console Management for all IT assets

The modular IOLAN SCG R/U Console Server supports both RS232 RJ45 and USB connectivity to console ports on equipment such as Cisco routers, switches, firewalls, servers (Solaris, Windows, Unix and Linux) PBXs, network storage equipment and security appliances through an IP network. For decades the highly reliably RS232 RJ45 port has been the standard for Console Admin port access. Now, IT equipment manufacturers like Cisco, Juniper, Dell, HPE, Huawei and others are delivering devices with USB Console Admin Ports. The modular design of the IOAN SCG R/U provides support for both types of admin ports in one Console Management solution. The interface modules allow the user to swap, upgrade and scale to any “mix-and-match” combination of 16-port USB 3.0 or RS-232 RJ45 interface module cards. You can purchase the IOLAN SCG R/U Console Server fully populated or partially populated so that you can swap and add modules as your needs grow or change.

IOLAN SCG Interface Options

The Perle IOLAN SCG is the only industry solution that can support up to 50 high-density USB 3.0 ports that are compatible with all manufacturers’ USB solutions.

The RS232 RJ45 ports are software configurable to use straight thru or rolled cables to connect your Cisco equipment. In addition, a DCD pin can be configured for 3rd party devices that need this extra signal. The means the Perle IOLAN SCG supports more serial devices than any other Console Server on the market.

Advanced Network Security Features, Authentication and Data Encryption

IT administrators are required to ensure network data transmissions, and all access to remote console admin ports on IT equipment, is secure. When using IOLAN SCG Console Servers, data management information is protected through standard encryption tools such as Secure Shell (SSH) and Secure Sockets Layer (SSL). Support for authentication schemes such as RADIUS, TACACS+, LDAP, Kerberos, NIS and RSA Security’s SecurID tokens ensures access to equipment and data is limited to authorized users.

By using encryption technologies, an IOLAN SCG Console Server protects sensitive and confidential data before being sent across a corporate Intranet or public Internet. For compatibility with peer encryption devices, all the major encryption ciphers such as AES, 3DES, RC4, RC2 and CAST128 are fully supported.

Recognized as the most secure method for communicating to remote private networks over the Internet, the IPSec standard provides robust authentication and encryption of IP packets at the network layer of the OSI model. As a standard it is ideal for multi-vendor interoperation within a network, providing flexibility and the ability to match the right solution for a particular application.

Redundancy features for fault tolerant network access and uptime

Every IOLAN SCG R/U Console Server comes with redundant copper and fiber Ethernet network access support with bonding and IP filtering. Any dual combination of the two 10/100/1000Base-T Copper Ports and two 100/1000Base-X SFP Fiber Ports can be used to meet your unique network access requirements. When connecting to a fiber network, the pluggable SFP ports allow for flexible network configurations using SFP Optical Transceivers supplied by Perle, Cisco or other manufacturers of MSA compliant SFPs. This unique fault tolerant design, with Redundant Path technology, assures availability to Console Management ports through Active Standby or Dual Network Access modes.

Protection against electrostatic discharges and power surges is provided with robust 15Kv ESD protection circuitry on each console port.

In addition, Dual AC Power ensures your IOLAN stays up and running should the primary power source fail.

Easy Set-up, Configuration and Front Panel Display and Keyboard

The IOLAN SCG R/U is incredibly easy to get up and running on the the network. The Front Panel Display and Keyboard allows a user to assign an IP address directly through the display wihtout a direct PC connection. The rest of the unit can then be configured over the network using a variety of configurator options including, Perle Easy Config Wizard, Perle Device Manager, WebManager, CLI, etc.

The Front Panel Display is also a convenient way to monitor and trouble-shoot RS232, USB and Ethernet port activity.

For large scale roll-outs, the Micro SD Card slot can be used to back-up and restore configuration files as well as load new firmware. Perle is committed to eliminating configuration hassles for all IOLAN’s on your IP network.

Flexible and Reliable Serial to Ethernet Connections

An IOLAN SCG Console Server is ideal for connecting serial based COM port, UDP or TCP socket based applications to remote devices. Perle’s TruePort re-director provides fixed TTY or COM ports to serial based applications enabling communication with remote devices connected to Perle IOLAN’s either in encrypted or clear text modes.

TrueSerial® packet technology delivers the most authentic serial connections across Ethernet for serial protocol integrity.

You can also tunnel serial data between devices across an IP network.

By choosing a Perle IOLAN SCG Console Server you can rest assured that virtually any device with a serial COM port will operate in conjunction with your desired application exactly as it did when you had it directly connected. In the unlikely event that the Perle IOLAN Device Server does not enable this out of the box, Perle will make it work with customer installable “Device Plug-ins” .

Advanced IP Technology

With support for IPv6 the IOLAN SCG provides organizations with investment protection to meet this rapidly growing standard.

Demand for IPv6, which is compatible with IPv4 addressing schemes, is driven by the need for more IP address. With the implementation and rollout of advanced cellular networks, a robust method is needed to handle the huge influx of new IP addressable devices on the Internet. In fact, the US Department of Defense has mandated that all equipment purchased be IPv6 compatible. In addition, all major Operating Systems such as Windows, Linux, Unix and Solaris, as well as routers, have built-in support for IPv6.

It is therefore important for end users and integrators to select networking equipment that incorporates the IPv6 standard. The IOLAN line with support for IPv6 already built in, is the best choice in serial to Ethernet technology.

More reasons that make the IOLAN SCSG Console Servers the preferred choice:

  • FIPS 140-2 – Cryptographic modules meet US Government NIST compliancy.
  • Clustering – Provides a single view of all out of band console ports. Ideal for large data centers.
  • Primary/Backup host functionality enables automatic connections to alternate hosts should the primary TCP connection go down.
  • EasyPort Web – Access equipment serial console ports by using your java-enabled Internet browser.
