Cisco UCS E-Series Server Modules
The Cisco UCS E-Series Servers (E-Series Servers) are the next generation of Cisco UCS Express
servers. E-Series Servers are a family of size, weight, and power efficient blade servers that are housed
within the Generation 2 Cisco Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated
Services Router. These servers provide a general purpose compute platform for branch-office
applications deployed either as bare-metal on operating systems, such as Microsoft Windows or Linux;
or as virtual machines on hypervisors, such as VMware vSphere Hypervisor™, Microsoft Hyper-V, or
Citrix XenServer.
Compact Flash
The Cisco ISR 4451-Xs use a USB to Compact Flash.
Note
Do not run the router without a Compact Flash card installed. Cisco IOS-XE will not come up without
a compact flash card in the router.
Solid State Drives
The NIM slot 3 in the Cisco ISR 4451-X supports a field-replaceable solid state drive module with a
dual-SSD SATA slot.
The SSD slot is always powered up. The SSDs are hot-swappable as part of normal operation. See the
“
Overview of the SSD Carrier Card NIM (NIM-SSD), page 6-6
” section for more information.
