ToR and Aggregation Switches
Catalyst 4948E Series
WS-C4948E-E & WS-C4948E-S
Built on the success of the original 4948, the 4948E is Cisco’s premier Top-of-Rack (ToR) platform offera a non-blocking architecture and introduces IPv6 support in hardware. Additionally, the 4948E also offers 4 x uplinks ports which may be used with either SFP+ (10GE) or SFP (GE) modules to provide the desired performance and resiliency. The 4948E continues the tradition of high availability introduced by the original 4948 by offering redundant AC or DC power supplies. The 4948E is offered with either basic L2/L3 (WS-C4948E-S) or advanced L3 (WS-C4948E-E) support.
Catalyst 4948 Series
WS-C4948-S, WS-C4948-E, WS-C4948-10GE-S & WS-C4948-10GE-E
The 4948 series is Cisco’s original Top-of-Rack platform, with a non-blocking switch fabric to support the most demanding forwarding environments and high density 10/100/1000 deployments. It should be noted that the entire 4948 & 4948E series is one of the few 1 RU systems that supports dual, fully redundant, hot swappable power supplies, making it a great choice for those requiring the highest degree of high availability in a compact 1 RU form factor. We are offering both the “-S” and -E” varieties of the 4948 (WS-C4948-S and WS-C4948-E) and 4948-10GE (WS-C4948-10GE-S and WS-C4948-10GE-E) to support either basic L2/L3 or advanced L3 environments, respectively. It should also be noted that the 4948 does not support IPv6 in hardware, this however does not present major concern in most environments. Overall, the 4948 is a great high performance switch and one of the few supporting truly redundant power supplies (in either AC or DC). For those customers requiring support for IPv6, please refer to the 4948E series products above.
Catalyst 4900M Series and 10GE modules
WS-C4900M, WS-X4904-10GE, WS-X4908-10GE, PWR-C49M-1000AC
The 4900M is a 2RU modular switch targeted for high performance 10GE Top-of-Rack (ToR) and aggregation deployments, offering full 10GE support or the flexibility of mixing and matching GE and 10GE interfaces through the addition of modular interface cards and adapters. 8 non-blocking 10GE ports are included in this chassis with two module slots to accommodate a variety of modules including a 1:1 4-port X2-based 10GE module (WS-X4904-10GE) and the 2:1 8-port 10GE module (WS-X4908-10GE), both of which are also on special. The 2:1 module supports the use of the TwingGig converter module (CVR-X2-SFP10G) for those needing the flexibility of both 10GE and GE or those seeking an easy transition from GE to 10GE. All X2-based 10GE ports support the use of the “OneX” converter module (CVR-X2-SFP10G) for those customers requiring SFP+ connectivity.
