I/o connectivity, Redundancy support, Guidelines for installing connectivity modules – Dell POWEREDGE 1855 User Manual
Page 22
Unless your system is configured according to these guidelines, do not perform any of the following actions:
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 version
1.1. If the DRAC/MC module currently in the system is version 1.0, you must upgrade the firmware of the current module to 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.
Guidelines for Installing Connectivity Modules
The following guidelines must be used when populating I/O modules. See
for I/O bay locations.
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.
lists the valid I/O module configurations. See
for I/O bay locations.

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.
