Access All Your Serial and Network Devices from Anywhere in the World
The B093-008-2E4U-M 8-port console server provides secure in-band (primary network) and out-of-band (alternate channel) remote access to serial- and network-connected routers, network switches, firewalls, PBX systems, UPS systems, PDUs and other devices. It offers reliable network connectivity with dual Gigabit primary and failover Ethernet ports for redundancy. You can use it in a wide variety of applications, including wiring closets, branch offices, point-of-sale and other remote sites where quick resolution of network issues is imperative.
Simple and Flexible Accessibility
Eight serial RS-232 console ports are configured to use standard Cat5e/6 patch cable when connecting to Cisco devices. They integrate with industry-standard directory servers using TACACS+, RADIUS, LDAP and Kerberos authentication. Provides 4Gb of internal NAND flash memory.
Built-In PSTN Modem for Out-of-Band Access
A V.92 serial data/fax modem enables out-of-band (alternate channel) access when remote sites experience a network outage. You can dial into the rack console from anywhere at any time, eliminating the costly need for additional USB modems that can be accidentally disconnected or have compatibility issues.
Each gateway can port forward to an unlimited number of locally networked hosts (computers, routers). This rack console also includes a built-in stateful firewall and embedded DHCP server to host a separate management LAN for critical traffic.
The Utmost in Security to Keep Your Sensitive Data Private
The B093-008-2E4U-M supports the following security features and standards: PCI DSS 3.2, FIPS 140-2, SSL and SSH, stateful firewall, OpenVPN and IPSec VPN support. The embedded FIPS 140-2 OpenSSL cryptographic module is validated to meet FIPS 140-2 standards and has received Certificate #2473.
PowerMan PDU and UPS Support
This 8-port console server uses PowerMan for PDU and RPC management and Network UPS Tools for UPS system monitoring and management. It provides support for Tripp Lite and other power products, so you can remotely manage power to your connected equipment.
USB Console and Digital I/O (DIO) Ports
Four USB 2.0 console ports allow connection to newer devices with USB console ports, such as Tripp Lite’s wide variety of PDUs and UPS systems with WEBCARDLX and LX Platform remote management cards. Two DIO ports are included for connecting compatible devices, such as drive relays and alarms.
Compact Design for Convenient Mounting
The heavy-duty steel housing comes with mounting brackets for easy installation in an EIA-standard 19-inch rack. Its fanless form factor also allows desktop deployment on four included rubber feet that help prevent the unit from sliding.
TAA-Compliant for GSA Schedule Purchases
This serial console server is compliant with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
4-Year Warranty and Environmentally Responsible Design
The B093-008-2E4U-M comes with a 4-year warranty. It’s manufactured in compliance with strict RoHS specifications, reflecting Tripp Lite’s commitment to environmental responsibility.
