Hardware Features of Cisco 4000 Series ISRs
Cisco UCS E-Series Server Modules
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 Cisco 4000 Series Integrated Services
Router. For more information on the E-Series Server Modules, see the
Configuration Guides.
System Flash
Depending on the model that you have purchased, the routers use a CompactFlash or an eUSB flash for
the internal bootflash memory. The CompactFlash and eUSB flash stores the operating system software
image.
The CompactFlash is applicable to only Cisco 4451-X ISR. Each model supports 1 internal
CompactFlash 8-GB, 16-GB, or 32-GB memory card. The CompactFlash is located behind the fan tray
on the router chassis.
Cisco 4431 ISRs have a eMMC flash device. The device supports 8GB, 16GB, or 32 GB.
Cisco 4300 Series ISRs have an onboard flash device or an eMMC flash device. It supports 8GB or
16GB.
For Cisco 4451-X ISR, you must use Cisco-qualified CompactFlash cards. The use of any other cards
Note
during normal network operation can affect system performance or reliability.
Do not run the router without a CompactFlash card installed. Cisco IOS XE software does not boot
Note
without a flash card in the router.
Solid State Drives
The NIM slots in the router support a field-replaceable solid state drive module with a dual-SSD SATA
slot. The NIM can be installed in any bay slot 0. The SSDs are hot-swappable as part of normal
operation. See the "Locate Internal and External Slots for Modules on Cisco 4331 ISR" section on page
6-9 section for more information.
Cisco 4300 ISR platforms support an optional internal SSD mSATA. This device is not hot-swappable
and requires opening the chassis to service or upgrade.
Cisco 4461 ISR platform supports an optional internal M2.SSD with the capacity of 800 G. See the
"Locate Internal and External Slots for Modules on Cisco 44611 ISR" section on page 6-9 section for
more information.
Packet Voice Digital Signal Processor Modules
The Packet Voice Digital Signal Processor Modules (PVDM4s) add additional voice capabilities to the
routers. The PVDM4 is installed inside the chassis of the router. See the "Install PVDM4 on the
Motherboard of Cisco 4400 Series ISRs" section on page 6-33 for installation instructions.
