t and Gigabit Ethernet products in a single stack allowing customers to migrate their desktops to Gigabit while maintaining the same features and simplified manageability from an ERS 4500 stack. - The need to maintain an “Secure Always On Network" is delivered through support of fail-safe stacking and advanced resiliency technology. The ERS 4500 products provide both the scalability and resilience by enabling customers to add switches or replace switches in a stack while maintaining stack integrity even in the unlikely event of switch or cable failure occurs. - Advances security capabilities enable the ERS4500 switches to provide multi-layered network defence. Security applications such as DHCPsnooping, ARP Inspection and BPDU filtering enable the switches to protect the network against malicious network attacks. Advanced security capabilities enable end user device health assessment, quarantine and remediation through the use of Nortel Secure Network Access.Specification Nortel 4548GT - AL4500A04-E6 Feature Product Features Technical details Source data-sheet ICEcat.biz Connectivity Ports quantity 52 Connectivity technology Wired Ethernet LAN (RJ-45) ports quantity 48 SFP ports quantity 4 I/O ports 2 x HiStack Weight & dimensions Dimensions W x D x H 438.2 x 368.3 x 43.7mm Energy management Power over Ethernet (PoE) Support N Power consumption 150W Heat dissipation 415BTU/h Power requirements AC 100-240V, 50-60Hz Environmental conditions Non-operating relative humidity (non-condensing) 10 - 90% Operating temperature range (T-T) 0 - 55°C Storage temperature range (T-T) -25 - 55°C Endurance Mean time between failures (MTBF) 247641h Networking Address table size 8000entries Flow control support Y Link aggregation Y Sound emission Noise level 39.5dB Data transmission Maximum data transfer rate 1Gbit/s Supported data transfer rates 10/100/1000 Mbit/s Switching (Description excerpted from: Pc Onestopshop)
