Dell POWEREDGE 1855 - Manual (Page 15)

l Upgrade DRAC/MC firmware
l Issue a software reset command for a DRAC/MC, such as racadm racreset
l Reseat a DRAC/MC module
l Cause a DRAC/MC failover event, such as removing the network cable from the primary DRAC/MC
Performing any of these actions will power off and stop traffic on the bay 2 or bay 4 I/O module, resulting in data loss.
When initiated, the DRAC/MC version 1.1 (or later) firmware algorithm must find a module in bay 1 before bay 2 and a module in bay 3 before bay 4.
Otherwise, the module in bay 2 or bay 4 will be powered off if you perform a firmware upgrade procedure on the DRAC/MC, cause a DRAC/MC failover, or reset
the DRAC/MC.
See the current Dell Remote Access Controller/Modular Chassis User's Guide at support.dell.com for more information about configuring your DRAC/MC system.
Redundancy Support
If you are adding a DRAC/MC version 1.1 (or later) module to a system to enable redundancy, the firmware levels of both DRAC/MC modules must be at least
version 1.1. If the DRAC/MC module currently in the system is version 1.0, you must upgrade the firmware of that module to at least version 1.1 prior to
installing the new DRAC/MC version 1.1 (or later) module.
See the latest Dell Remote Access Controller/Modular Chassis User's Guide at support.dell.com for more information about firmware updates and installing
redundant DRAC/MC modules. This guide also provides complete instructions on how to set up and operate that version of the module.
I/O Connectivity
The system offers several options for connectivity through a combination of embedded Ethernet controllers, optional I/O daughter cards on the server module,
and chassis I/O modules in the rear of the chassis. An I/O module's green system/diagnostic indicator is off when the module is properly operating or is off and
blinks when the module is not properly operating.
The following guidelines must be used when populating I/O modules.
l Insert a connectivity module into I/O bay 1 before installing a connectivity module into I/O bay 2.
I/O bays 1 and 2 support only Gb Ethernet switch or pass-through modules.
l Insert a connectivity module into I/O bay 3 before installing a connectivity module into I/O bay 4.
Ensure that the connectivity modules installed in I/O bays 3 and 4 are of the same fabric type.
l I/O bay 3 connects to port 1 on the daughter card (optional) installed in the server module. This bay must be populated if there is a daughter card
installed in the server module. The type of I/O module installed in this bay must match the type of daughter card installed in the server module. For
example, a Fibre Channel I/O module requires that a Fibre Channel daughter card be installed in the server module.
Table 1 -10 lists the valid I/O module configurations. See Figure 1 -5 for I/O bay locations.
Table 1-10. Valid I/O Module Configurations
PowerConnect 5316M Ethernet Switch Module
The PowerConnect 5316M Ethernet switch module is a 16-port switch with 6 uplinks and 10 downlinks (see Figure 1 -12 ). The uplinks connect to the external
Ethernet network and operate at 10/100/1000 Mb. The downlinks connect to the embedded Ethernet controller on the server module and operate at 1000 Mb
only.
NOTE: A DRAC/MC module's firmware version is displayed on its web-based GUI or by typing the command getsysinfo or racadm getsysinfo.
NOTE: DRAC/MC version 1.1 (or later) firmware uses a different MAC address than the MAC address reported by DRAC/MC version 1.0 firmware.
Therefore, a DHCP-assigned dynamic IP address may change after updating to the DRAC/MC version 1.1 firmware.
