Transceivers

Are transceivers shipped with the MPX 8005/8015/8200/8400/8600/8800 appliance?
No. Transceivers are available for purchase separately. Contact your Citrix sales representative to order transceivers for your appliance.

Why does the 10G SFP+ transceiver autonegotiate to 1G speed?
Autonegotiation is enabled by default on the 10G SFP+ ports into which you insert your 10G SFP+ transceiver. When a link is established between the port and the network, the speed is autonegotiated. For example, if you connect the port to a 1G network, the speed is autonegotiated to 1G.
Can I insert a 1G transceiver into a 10G slot?

The 10G slot supports copper 1G transceivers, which can operate at up to 1 Gbps in a 10 Gbps slot.

Note that you cannot insert a 10G transceiver into a 1G slot.

The following table shows the compatibility matrix of transceivers and ports available on the NetScaler appliance.

What is QSFP+?

QSFP+ stands for Quad Small Form-factor Pluggable, which is a small, hot-pluggable transceiver for connecting data devices. This transceiver is used for 40G interfaces.

QSFP+ to Four SFP+ Copper Breakout Cables—These cables connect to four SFP+ 10GE ports of a NetScaler appliance on one end and to a QSFP+ 40G port of a Cisco switch on the other end.

Support for 40G connectivity—NetScaler models that have at least four 10G SFP+ ports connect to Cisco 40G interfaces by aggregating four of the 10G SFP+ ports to form a 40G link aggregation channel. QSFP to Four port SFP+ Copper Breakout Cable QSFP-4SFP10G-CU3M (reports as L45593-D178-C30) is used.

Which NetScaler appliances support the QSFP-4SFP10G-CU3M (reports as L45593-D178-C30) Breakout Cable?
NetScaler appliances that have at least four 10G SFP+ ports support this cable. The following appliances have at least four 10G SFP+ ports:
  • MPX 11500/13500/14500/16500/18500/20500
  • MPX 17550/19550/20550/21550
  • MPX 11515/11520/11530/11540/11542
  • MPX 22040/22060/22080/22100/22120
  • MPX 24100/24150
  • MPX 25100T/25160T

QSFP-4SFP10G-CU3M breakout cable is supported by NetScaler release 9.3 build 65.8 or later, and release 10.1 build 122.17 or later.

Power Supplies

Is the power supply on the NetScaler MPX 5500 and MPX 5550/5650 appliances field replaceable?
No. The power supply on the NetScaler MPX 5500 and MPX 5550/5650 appliances is fixed.
Does the MPX 8005/8015/8200/8400/8600/8800 appliance ship with two power supplies?
No. The MPX 8005/8015/8200/8400/8600/8800 appliance supports dual power supplies but ships with one power supply. Contact your Citrix sales representative to order a second power supply.

Are power supplies hot-swappable?
Yes. If the appliance has two power supplies, you can replace one power supply without shutting down the appliance, provided the other power supply is working.

Rack and Rail

Do you have different rail kits for 1U and 2U appliances?
No. All MPX and SDX appliances use the same rail kit. The kit contains two pairs of slide rails, of different lengths, for a 1U and a 2U appliance.
Which rail kit should I buy?

The appliance ships with the standard 4-post rail kit that fits racks from 28-38 inches.

The compact 4-post rail kit for racks from 23-33 inches, or the 2-post rail kit for 2-post racks, has to be purchased separately. Contact your Citrix sales representative to order the appropriate kit.

What are the maximum and the minimum lengths of the outer rack rails?
The length of a standard outer rack rail is from 28 to 38 inches. The length of a shorter outer rack rail is from 23 to 33 inches.
What is the space required between the front post and rear post of the rack?
Standard racks require 28–38 inches between the front and rear posts. Shorter racks require from 23 to 33 inches.
How far can an appliance extend from the front post of the rack?
The chassis can extend up to 1.25 inches from the front post for all NetScaler MPX and SDX appliances.
How much space is required for maintaining the front and rear area of an appliance?
Minimum clearance areas of 36 inches for the front area and 24 inches for the rear area are required for maintenance of all NetScaler MPX and SDX appliances.

Lights Out Management (LOM) Port

Which LOM features are supported on the NetScaler MPX Appliance?
The MPX 8005/8015/8200/8400/8600/8800, MPX 11500/13500/14500/16500/18500/20500, and MPX 17550/19550/20550/21550 have an Intelligent Platform Management Interface (IPMI), also known as the Lights out Management (LOM) port, on the front panel of the appliance. The following three LOM features are supported on those platforms:
  • Configuring the LOM port
  • Power cycling the appliance
  • Performing a core dump
Can the LOM interface be configured to accept only encrypted Virtual Network Computer (VNC) sessions on TCP port 5900?

Yes, customers who enable Transport Layer Security (TLS) on their LOM interface will have their VNC connections delivered over TLS as well.

For more information on LOM security guidelines, see Secure Deployment Guide for NetScaler MPX, VPX, and SDX Appliances.

Can the version of SSH used on the LOM interface be upgraded? Is there a patch available?
Individual components of the LOM cannot be upgraded independently. You must upgrade the entire LOM firmware as a package. The latest available LOM package can be found on the Citrix downloads website under LOM Firmware Upgrade.
Is it possible to add a third-party or self-signed SSL certificate to the LOM interface?
Yes, you can enable SSL on the latest binaries for third-party and self-signed SSL certificates, except on the 88XX models. On those models, the current LOM release does not support third-party certificates.
