HPE ProLiant SL4540 Gen8 Rack Options
Rack and console hardware for the HPE ProLiant SL4540 Gen8, new and refurbished. This is a 4.3U chassis weighing up to 220 lb fully populated, in a rack HPE specifies at 1200mm deep — so depth, weight and how the odd 4.3U height is spaced are settled before any console decision, and this category is where the console decision is made.
SL4540 Gen8 Rack Specifications
- Form factor: 4.3U, measuring 7.47 x 17.45 x 35.34in (18.96 x 44.33 x 89.97cm) with the bezel and fan extension kit
- Weight: up to 220 lb (99.8 kg) fully populated — heavy enough that the drive section is usually filled after the chassis is racked
- Rack depth: HPE requires a rack 1200mm deep, for the cable management arm behind the chassis and the rear PDU
- Height options: a 0.66U spacer blank squares the chassis to an even 5U and fits eight in a 42U rack; a 13U rack adapter kit instead groups three chassis into 13U, without the spacer
- Rails: one rail kit per chassis — a documented platform requirement rather than a part listed on this page
- Console hardware listed here: TFT7600 G2 rackmount KVM consoles, analog console switches, G2 switches with virtual media and CAC, IP console switches and the KVM CAT5 USB interface adapter
- Thermal envelope: 50 to 95 degrees F (10 to 35 degrees C) inlet at sea level, derating 1.8 degrees F per 1000ft to a maximum of 10,000ft
The rails are a platform fact, not a part on this page. HPE documents one 4.3U rail kit per chassis, a 0.66U spacer blank to square the height to an even 5U, and a 13U adapter kit for three chassis — while the parts listed here are consoles, switches and interface adapters. Plan the rack first: 1200mm deep, up to 220 lb loaded.
What Does It Take to Rack an SL4540 Gen8?
| Requirement | The platform answer | Worth knowing |
|---|---|---|
| Rails | A 4.3U server rail kit | One per chassis, every chassis in the rack |
| Even rack spacing | A 0.66U spacer blank | Makes 5U per chassis and fits eight in a 42U rack |
| Dense racking | A 13U rack adapter kit | Three chassis in 13U; the spacer is not used with it |
| Rack depth | 1200mm | Holds the cable management arm and the rear PDU |
| Console access | A KVM console or a console switch | What this category actually lists |
The first three rows are the honest caveat on this page: they are documented platform requirements, and they are not what this category stocks. If the chassis is already racked, that costs nothing; if it is not, the rails and any spacer or adapter kit need sourcing alongside it. What remains here is console access.
Choosing the Right SL4540 Gen8 Rack Options
- Decide console access per rack, not per server. A switch pays off across a row of chassis; a rackmount KVM console is simpler where one rack needs a head.
- Analog, virtual media and IP switches are different jobs. Analog switches serve a keyboard and screen in the rack; IP and virtual media switches with CAC add remote access and smart card authentication.
- Count interface adapters separately. CAT5 console switches need one USB interface adapter per attached server, and a multi-node chassis is several servers here.
- Remember iLO is already there. Every node has iLO 4 on a dedicated management port, so the hardware here is for working at the rack itself.

SL4540 Gen8 Rack Options FAQ
How much rack space does an SL4540 Gen8 need?
The chassis is 4.3U. A 0.66U spacer blank makes it an even 5U, which fits eight in a 42U rack, while a 13U rack adapter kit groups three chassis into 13U instead.
How deep a rack does an SL4540 Gen8 need?
HPE specifies 1200mm. The chassis is 35.34 inches (89.97 cm) deep with the bezel, and the extra depth is for the cable management arm behind it and the rear PDU.
How much does an SL4540 Gen8 weigh?
Up to 220 lb (99.8 kg) with all drives, power supplies and processors installed. Populating the drive section after the chassis is racked is the usual approach.
Does this category include rails for the SL4540 Gen8?
No. HPE documents a 4.3U server rail kit, one per chassis, and a 0.66U spacer blank, but the parts listed here are KVM consoles, console switches and interface adapters.
What inlet temperature does the SL4540 Gen8 tolerate?
50 to 95 degrees F (10 to 35 degrees C) at sea level, derating 1.8 degrees F per 1000 ft to 10,000 ft. Performance may be reduced above 86 degrees F or with a fan fault.
Do I need a KVM switch if the server has iLO?
Not for remote management - every node carries iLO 4 on a dedicated port. A console or switch is for working at the rack itself, or for access when the network to iLO is down.
