Every port on the rear panel, explained
Click a card to light up those ports on the panel above.
2 LOM network ports2 on the panel
Two 1 GbE RJ45 ports on the optional LAN on Motherboard (LOM) card, at the left of the lower rear I/O.
The link light is green at full speed and amber at a lower speed; the activity light blinks green when data moves.
iDRAC9 management port1 on the panel
The dedicated Ethernet port for iDRAC9. Patch it to your management network to power the server on and off, open the remote console and update firmware from anywhere.
USB 2.0 and USB 3.02 on the panel
Two stacked USB-A ports: the top one is USB 2.0 and the bottom one USB 3.0. The front has another USB 2.0 port plus a micro-USB iDRAC Direct port for a laptop.
VGA video1 on the panel
A 15-pin VGA port driven by the integrated Matrox G200 (up to 1920 x 1200). There is also a VGA port on the front.
Power supplies2 on the panel
PSU 1 sits at the lower left of the rear and PSU 2 at the lower right. See power supplies for the options and the cord each one takes.
Also on the back
- OCP NIC slot: takes an optional OCP 3.0 card with 1 GbE x 4, 10 GbE x 2 or x 4, 25 GbE x 2 or x 4, or 100 GbE x 2. You can run the LOM card, the OCP card or both.
- Risers 1 to 4: riser 1 holds slots 1 and 2, riser 2 slots 3 and 6, riser 3 slots 4 and 5, and riser 4 slots 7 and 8. Some configurations replace slots with rear drive modules or liquid cooling.
- BOSS module: the boot module between risers 1 and 3, holding two M.2 NVMe SSDs.
- System ID button: press to flash the ID light so you can find the server in the rack. Hold more than 5 seconds during a hung POST for BIOS progress mode, or more than 15 seconds to reset the iDRAC.
- Optional serial port: a 9-pin card that installs like an expansion slot bracket.
PowerEdge R660 power supplies
| PSU | Input | Cord | Heat (max) |
|---|---|---|---|
| 700 W Titanium | 200 to 240 V AC or 240 V DC | C13 | 2625 BTU/hr |
| 800 W Platinum | 100 to 240 V AC or 240 V DC | C13 | 3000 BTU/hr |
| 1100 W Titanium | 100 to 240 V AC or 240 V DC | C13 | 4100 BTU/hr |
| 1400 W Platinum or Titanium | 100 to 240 V AC or 240 V DC | C13 | 5250 BTU/hr |
| 1400 W Titanium 277 V | 277 V AC or 336 V HVDC | 277VAC/HVDC | 5250 BTU/hr |
| 1800 W Titanium | 200 to 240 V AC or 240 V DC | C15 | 6750 BTU/hr |
| 2400 W Platinum | 100 to 240 V AC or 240 V DC | C19 | 9000 BTU/hr |
| 2800 W Titanium | 200 to 240 V AC or 240 V DC | C21 | 10500 BTU/hr |
| 3200 W Titanium 277 V | 277 V AC or 336 V HVDC | 277VAC/HVDC | 12000 BTU/hr |
| 1100 W DC | -48 to -60 V DC | C13 | 4265 BTU/hr |
On 100 to 120 V circuits the 2400 W unit drops to 1400 W and the 1100 W and 1400 W units drop to 1050 W. The 1800 W unit can use a C13 cord with a C14 to C15 jumper, and the 2800 W unit a C19 cord with a C20 to C21 jumper.
Both PSUs must be the same type, wattage and label. Older-generation PowerEdge PSUs don't work here even at the same rating. If they mismatch, replace the one that is blinking.
| PSU handle light | What it means |
|---|---|
| Green | Power connected and the PSU is working |
| Blinking amber | Problem with the PSU |
| Off | No power connected |
| Blinking green | PSU firmware updating: don't unplug it |
| Blinks green 5 times, then off | Hot-added PSU doesn't match the other one |
First boot: setup keys and iDRAC
- F2
- System Setup
- F10
- Lifecycle Controller
- F11
- Boot Manager
- F12
- PXE boot
- Patch the iDRAC9 port to your management network.
- If the server has the LCD bezel, open Setup, then iDRAC, and pick DHCP or a static IP. View, then iDRAC IP shows the address.
- No bezel? Plug a laptop into the front iDRAC Direct micro-USB port with a cable no longer than 3 ft.
- Check the information tag on the front for the iDRAC default password if your server shipped with secure default access.
PowerEdge R660 LED codes
| System health / ID light | What it means |
|---|---|
| Solid blue | Powered on and healthy |
| Blinking blue | System ID mode is on |
| Solid amber | Fail-safe mode |
| Blinking amber | A fault: check the System Event Log |
The five status lights on the left control panel (drive, temperature, electrical, memory and PCIe) turn solid amber when that part of the system has an error.
On the optional LCD bezel the backlight is white when everything is normal and amber with an error code when something needs attention, even with the server off.
Memory and drives
| RDIMM (4th Gen Xeon) | Max, one processor | Max, two processors |
|---|---|---|
| 16 GB single rank | 256 GB | 512 GB |
| 32 GB dual rank | 512 GB | 1 TB |
| 64 GB dual rank | 1 TB | 2 TB |
| 128 GB quad rank | 2 TB | 4 TB |
| 256 GB octa rank | 4 TB | 8 TB |
With 5th Gen Xeon, 96 GB RDIMMs are also supported (up to 3 TB with two processors) and memory runs at 5600 or 6400 MT/s. DDR4 is not supported and DIMM slots are not hot-pluggable. Front drives come in 3.5 in., 2.5 in. or EDSFF E3.S layouts, with optional rear drive modules.
Rack and room requirements
- Standard operation is 50 to 95 F (10 to 35 C) out of direct sunlight, with the limit dropping about 1.8 F for every 1,000 ft above 2,950 ft.
- Maximum operating altitude is about 10,000 ft (3,050 m).
- The depth is about 27.6 in. ear to rear wall and about 29 in. to the PSU handles, so check your rack depth.
