3 online PSUs Two PSUs are connected to Grid A and one PSU is connected to
Grid B; they work in N+1 redundant mode.
2 online PSUs One PSU is connected to Grid A and another PSU is connected
to Grid B; they work in N:N redundant mode.
1 online PSU The PSU is connected to any one grid; it works in
non-redundant mode.
The power supplies in a IBM SAN50C-R Switch work in the following power
modes when FCoE ports are in ADMIN UP state:
3 online PSUs They work in N+1 redundant mode.
2 online PSUs They work in non-redundant mode.
1 online PSU It works in non-redundant mode. In this case, FCoE ports
automatically switch to an error-disabled state to save power for
FC and IP ports.
Supported Transceivers
The IBM SAN50C-R Switch supports the transceivers in the following list.
v 8-Gbps SW/LW, LC Enhanced Small Form-Factor Pluggable (SFP+)
v 10-GbE SR/LR/ER, LC, SFP+
v
16-Gbps SW/LW LC SFP+
v 4/8/16-Gbps Fibre Channel LW SFP+, DWDM, SM, DDM, 13 dB, 40 km
v 4/8/16-Gbps Fibre Channel LW SFP+, CWDM, SM, DDM, 13 dB, 40 km
v 4/8/16-Gbps Fibre Channel/FICON LW SFP+, DWDM, SM, DDM, 1550nm, 13
dB, 40 km
v 2/4/8-Gbps Fibre Channel LW SFP+, DWDM, SM, DDM, 80 km
v 2/4/8-Gbps Fibre Channel LW SFP+, CWDM, SM, DDM, 23dB, 70 km
v 2/4/8-Gbps Fibre Channel LW SFP+, SM, DDM, 80 km
Fibre Channel SFP+ Transceivers
The Fibre Channel SFP+ transceivers are field-replaceable and hot-swappable. You
can use any combination of SFP+ transceivers that are supported by the switch.
The only restrictions are that SWL transceivers must be paired with SWL
transceivers, and LWL transceivers must be paired with LWL transceivers, and the
cable must not exceed the stipulated cable length for reliable communications.
For more information about a specific IBM SFP+ transceiver, see the “Technical
Specifications” section on page B-1. SFP+ transceivers can be ordered separately or
with the IBM SAN50C-R Switch.
Note: Use only IBM-provided transceivers in the IBM SAN50C-R Switch. Each
transceiver is encoded with model information that enables the switch to verify
that the transceiver meets the requirements for the switch.
